+Subject: [PATCH] mips: bpf: Add eBPF JIT for 32-bit MIPS
+
+This is an implementation of an eBPF JIT for 32-bit MIPS I-V and MIPS32.
+The implementation supports all 32-bit and 64-bit ALU and JMP operations,
+including the recently-added atomics. 64-bit div/mod and 64-bit atomics
+are implemented using function calls to math64 and atomic64 functions,
+respectively. All 32-bit operations are implemented natively by the JIT,
+except if the CPU lacks ll/sc instructions.
+
+Register mapping
+================
+All 64-bit eBPF registers are mapped to native 32-bit MIPS register pairs,
+and does not use any stack scratch space for register swapping. This means
+that all eBPF register data is kept in CPU registers all the time, and
+this simplifies the register management a lot. It also reduces the JIT's
+pressure on temporary registers since we do not have to move data around.
+
+Native register pairs are ordered according to CPU endiannes, following
+the O32 calling convention for passing 64-bit arguments and return values.
+The eBPF return value, arguments and callee-saved registers are mapped to
+their native MIPS equivalents.
+
+Since the 32 highest bits in the eBPF FP (frame pointer) register are
+always zero, only one general-purpose register is actually needed for the
+mapping. The MIPS fp register is used for this purpose. The high bits are
+mapped to MIPS register r0. This saves us one CPU register, which is much
+needed for temporaries, while still allowing us to treat the R10 (FP)
+register just like any other eBPF register in the JIT.
+
+The MIPS gp (global pointer) and at (assembler temporary) registers are
+used as internal temporary registers for constant blinding. CPU registers
+t6-t9 are used internally by the JIT when constructing more complex 64-bit
+operations. This is precisely what is needed - two registers to store an
+operand value, and two more as scratch registers when performing the
+operation.
+
+The register mapping is shown below.
+
+ R0 - $v1, $v0 return value
+ R1 - $a1, $a0 argument 1, passed in registers
+ R2 - $a3, $a2 argument 2, passed in registers
+ R3 - $t1, $t0 argument 3, passed on stack
+ R4 - $t3, $t2 argument 4, passed on stack
+ R5 - $t4, $t3 argument 5, passed on stack
+ R6 - $s1, $s0 callee-saved
+ R7 - $s3, $s2 callee-saved
+ R8 - $s5, $s4 callee-saved
+ R9 - $s7, $s6 callee-saved
+ FP - $r0, $fp 32-bit frame pointer
+ AX - $gp, $at constant-blinding
+ $t6 - $t9 unallocated, JIT temporaries
+
+Jump offsets
+============
+The JIT tries to map all conditional JMP operations to MIPS conditional
+PC-relative branches. The MIPS branch offset field is 18 bits, in bytes,
+which is equivalent to the eBPF 16-bit instruction offset. However, since
+the JIT may emit more than one CPU instruction per eBPF instruction, the
+field width may overflow. If that happens, the JIT converts the long
+conditional jump to a short PC-relative branch with the condition
+inverted, jumping over a long unconditional absolute jmp (j).
+
+This conversion will change the instruction offset mapping used for jumps,
+and may in turn result in more branch offset overflows. The JIT therefore
+dry-runs the translation until no more branches are converted and the
+offsets do not change anymore. There is an upper bound on this of course,
+and if the JIT hits that limit, the last two iterations are run with all
+branches being converted.
+
+Tail call count
+===============
+The current tail call count is stored in the 16-byte area of the caller's
+stack frame that is reserved for the callee in the o32 ABI. The value is
+initialized in the prologue, and propagated to the tail-callee by skipping
+the initialization instructions when emitting the tail call.

++ * Code overview
++ * =============
++ *
++ * - bpf_jit_comp.h
++ * Common definitions and utilities.
++ *
++ * - bpf_jit_comp.c
++ * Implementation of JIT top-level logic and exported JIT API functions.
++ * Implementation of internal operations shared by 32-bit and 64-bit code.
++ * JMP and ALU JIT control code, register control code, shared ALU and
++ * JMP/JMP32 JIT operations.
++ *
++ * - bpf_jit_comp32.c
++ * Implementation of functions to JIT prologue, epilogue and a single eBPF
++ * instruction for 32-bit MIPS CPUs. The functions use shared operations
++ * where possible, and implement the rest for 32-bit MIPS such as ALU64
++ * operations.
++ *
++ * - bpf_jit_comp64.c
++ * Ditto, for 64-bit MIPS CPUs.
++ *
++ * Zero and sign extension
++ * ========================
++ * 32-bit MIPS instructions on 64-bit MIPS registers use sign extension,
++ * but the eBPF instruction set mandates zero extension. We let the verifier
++ * insert explicit zero-extensions after 32-bit ALU operations, both for
++ * 32-bit and 64-bit MIPS JITs. Conditional JMP32 operations on 64-bit MIPs
++ * are JITed with sign extensions inserted when so expected.
++ *
++ * ALU operations
++ * ==============
++ * ALU operations on 32/64-bit MIPS and ALU64 operations on 64-bit MIPS are
++ * JITed in the following steps. ALU64 operations on 32-bit MIPS are more
++ * complicated and therefore only processed by special implementations in
++ * step (3).
++ *
++ * 1) valid_alu_i:
++ * Determine if an immediate operation can be emitted as such, or if
++ * we must fall back to the register version.
++ *
++ * 2) rewrite_alu_i:
++ * Convert BPF operation and immediate value to a canonical form for
++ * JITing. In some degenerate cases this form may be a no-op.
++ *
++ * 3) emit_alu_{i,i64,r,64}:
++ * Emit instructions for an ALU or ALU64 immediate or register operation.
++ *
++ * JMP operations
++ * ==============
++ * JMP and JMP32 operations require an JIT instruction offset table for
++ * translating the jump offset. This table is computed by dry-running the
++ * JIT without actually emitting anything. However, the computed PC-relative
++ * offset may overflow the 18-bit offset field width of the native MIPS
++ * branch instruction. In such cases, the long jump is converted into the
++ * following sequence.
++ *
++ * <branch> !<cond> +2 Inverted PC-relative branch
++ * nop Delay slot
++ * j <offset> Unconditional absolute long jump
++ * nop Delay slot
++ *
++ * Since this converted sequence alters the offset table, all offsets must
++ * be re-calculated. This may in turn trigger new branch conversions, so
++ * the process is repeated until no further changes are made. Normally it
++ * completes in 1-2 iterations. If JIT_MAX_ITERATIONS should reached, we
++ * fall back to converting every remaining jump operation. The branch
++ * conversion is independent of how the JMP or JMP32 condition is JITed.
++ *
++ * JMP32 and JMP operations are JITed as follows.
++ *
++ * 1) setup_jmp_{i,r}:
++ * Convert jump conditional and offset into a form that can be JITed.
++ * This form may be a no-op, a canonical form, or an inverted PC-relative
++ * jump if branch conversion is necessary.
++ *
++ * 2) valid_jmp_i:
++ * Determine if an immediate operations can be emitted as such, or if
++ * we must fall back to the register version. Applies to JMP32 for 32-bit
++ * MIPS, and both JMP and JMP32 for 64-bit MIPS.
++ *
++ * 3) emit_jmp_{i,i64,r,r64}:
++ * Emit instructions for an JMP or JMP32 immediate or register operation.
++ *
++ * 4) finish_jmp_{i,r}:
++ * Emit any instructions needed to finish the jump. This includes a nop
++ * for the delay slot if a branch was emitted, and a long absolute jump
++ * if the branch was converted.

++ * Mapping of 64-bit eBPF registers to 32-bit native MIPS registers.

++ * 1) Native register pairs are ordered according to CPU endiannes, following
++ * the MIPS convention for passing 64-bit arguments and return values.
++ * 2) The eBPF return value, arguments and callee-saved registers are mapped
++ * to their native MIPS equivalents.
++ * 3) Since the 32 highest bits in the eBPF FP register are always zero,
++ * only one general-purpose register is actually needed for the mapping.
++ * We use the fp register for this purpose, and map the highest bits to
++ * the MIPS register r0 (zero).
++ * 4) We use the MIPS gp and at registers as internal temporary registers
++ * for constant blinding. The gp register is callee-saved.
++ * 5) One 64-bit temporary register is mapped for use when sign-extending
++ * immediate operands. MIPS registers t6-t9 are available to the JIT
++ * for as temporaries when implementing complex 64-bit operations.
++ *
++ * With this scheme all eBPF registers are being mapped to native MIPS
++ * registers without having to use any stack scratch space. The direct
++ * register mapping (2) simplifies the handling of function calls.

+Subject: [PATCH] mips: bpf: Add new eBPF JIT for 64-bit MIPS
+
+This is an implementation on of an eBPF JIT for 64-bit MIPS III-V and
+MIPS64r1-r6. It uses the same framework introduced by the 32-bit JIT.

+Subject: [PATCH] mips: bpf: Add JIT workarounds for CPU errata
+
+This patch adds workarounds for the following CPU errata to the MIPS
+eBPF JIT, if enabled in the kernel configuration.
+
+ - R10000 ll/sc weak ordering
+ - Loongson-3 ll/sc weak ordering
+ - Loongson-2F jump hang
+
+The Loongson-2F nop errata is implemented in uasm, which the JIT uses,
+so no additional mitigations are needed for that.

+Subject: [PATCH] mips: bpf: Enable eBPF JITs
+
+This patch enables the new eBPF JITs for 32-bit and 64-bit MIPS. It also
+disables the old cBPF JIT to so cBPF programs are converted to use the
+new JIT.
+
+Workarounds for R4000 CPU errata are not implemented by the JIT, so the
+JIT is disabled if any of those workarounds are configured.

+Subject: [PATCH 1/2] crypto: arm/chacha-neon - optimize for non-block size
+ multiples
+
+commit 86cd97ec4b943af35562a74688bc4e909b32c3d1 upstream.
+
+The current NEON based ChaCha implementation for ARM is optimized for
+multiples of 4x the ChaCha block size (64 bytes). This makes sense for
+block encryption, but given that ChaCha is also often used in the
+context of networking, it makes sense to consider arbitrary length
+inputs as well.
+
+For example, WireGuard typically uses 1420 byte packets, and performing
+ChaCha encryption involves 5 invocations of chacha_4block_xor_neon()
+and 3 invocations of chacha_block_xor_neon(), where the last one also
+involves a memcpy() using a buffer on the stack to process the final
+chunk of 1420 % 64 == 12 bytes.
+
+Let's optimize for this case as well, by letting chacha_4block_xor_neon()
+deal with any input size between 64 and 256 bytes, using NEON permutation
+instructions and overlapping loads and stores. This way, the 140 byte
+tail of a 1420 byte input buffer can simply be processed in one go.
+
+This results in the following performance improvements for 1420 byte
+blocks, without significant impact on power-of-2 input sizes. (Note
+that Raspberry Pi is widely used in combination with a 32-bit kernel,
+even though the core is 64-bit capable)

+Subject: [PATCH 2/2] crypto: arm/chacha-neon - add missing counter increment
+
+commit fd16931a2f518a32753920ff20895e5cf04c8ff1 upstream.
+
+Commit 86cd97ec4b943af3 ("crypto: arm/chacha-neon - optimize for non-block
+size multiples") refactored the chacha block handling in the glue code in
+a way that may result in the counter increment to be omitted when calling
+chacha_block_xor_neon() to process a full block. This violates the skcipher
+API, which requires that the output IV is suitable for handling more input
+as long as the preceding input has been presented in round multiples of the
+block size. Also, the same code is exposed via the chacha library interface
+whose callers may actually rely on this increment to occur even for final
+blocks that are smaller than the chacha block size.
+
+So increment the counter after calling chacha_block_xor_neon().
+

+
+commit 5a0598695634a6bb4126818902dd9140cd9df8b6 upstream.
+
+The is_dead boolean is checked for every single packet, while the
+internal_id member is used basically only for pr_debug messages. So it
+makes sense to hoist up is_dead into some space formerly unused by a
+struct hole, while demoting internal_api to below the lowest struct
+cache line.

+Subject: [PATCH] MIPS: select CPU_MIPS64 for remaining MIPS64 CPUs
+
+The CPU_MIPS64 and CPU_MIPS32 variables are supposed to be able to
+distinguish broadly between 64-bit and 32-bit MIPS CPUs. However, they
+weren't selected by the specialty CPUs, Octeon and Loongson, which meant
+it was possible to hit a weird state of:
+
+ MIPS=y, CONFIG_64BIT=y, CPU_MIPS64=n
+
+This commit rectifies the issue by having CPU_MIPS64 be selected when
+the missing Octeon or Loongson models are selected.

+-Fixed Partitions
+-================
+-
+-Partitions can be represented by sub-nodes of a flash device. This can be used
+-on platforms which have strong conventions about which portions of a flash are
+-used for what purposes, but which don't use an on-flash partition table such
+-as RedBoot.
+-
+-The partition table should be a subnode of the flash node and should be named
+-'partitions'. This node should have the following property:
+-- compatible : (required) must be "fixed-partitions"
+-Partitions are then defined in subnodes of the partitions node.
++Deprecated: partitions defined in flash node
++============================================
+
+ For backwards compatibility partitions as direct subnodes of the flash device are
+ supported. This use is discouraged.
+ NOTE: also for backwards compatibility, direct subnodes that have a compatible
+ string are not considered partitions, as they may be used for other bindings.
+-
+-#address-cells & #size-cells must both be present in the partitions subnode of the
+-flash device. There are two valid values for both:
+-<1>: for partitions that require a single 32-bit cell to represent their
+- size/address (aka the value is below 4 GiB)
+-<2>: for partitions that require two 32-bit cells to represent their
+- size/address (aka the value is 4 GiB or greater).
+-
+-Required properties:
+-- reg : The partition's offset and size within the flash
+-
+-Optional properties:
+-- label : The label / name for this partition. If omitted, the label is taken
+- from the node name (excluding the unit address).
+-- read-only : This parameter, if present, is a hint to Linux that this
+- partition should only be mounted read-only. This is usually used for flash
+- partitions containing early-boot firmware images or data which should not be
+- clobbered.
+-- lock : Do not unlock the partition at initialization time (not supported on
+- all devices)
+-- slc-mode: This parameter, if present, allows one to emulate SLC mode on a
+- partition attached to an MLC NAND thus making this partition immune to
+- paired-pages corruptions

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Some devices use fixed partitioning with some partitions requiring some
+extra logic. E.g. BCM4908 may have multiple firmware partitions but
+detecting currently used one requires checking bootloader parameters.
+
+To support such cases without duplicating a lot of code (without copying
+most of the ofpart.c code) support for post-parsing callback was added.
+
+BCM4908 support in ofpart can be enabled using config option and results
+in compiling & executing a specific callback. It simply reads offset of
+currently used firmware partition from the DT. Bootloader specifies it
+using the "brcm_blparms" property.

+Subject: [PATCH] mtd: parsers: ofpart: limit parsing of deprecated DT syntax
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+For backward compatibility ofpart still supports the old syntax like:
+spi-flash@0 {
+ compatible = "jedec,spi-nor";
+ reg = <0x0>;
+
+ partition@0 {
+ label = "bootloader";
+ reg = <0x0 0x100000>;
+ };
+};
+(without "partitions" subnode).
+
+There is no reason however to support nested partitions without a clear
+"compatible" string like:
+partitions {
+ compatible = "fixed-partitions";
+ #address-cells = <1>;
+ #size-cells = <1>;
+
+ partition@0 {
+ label = "bootloader";
+ reg = <0x0 0x100000>;
+
+ partition@0 {
+ label = "config";
+ reg = <0x80000 0x80000>;
+ };
+ };
+};
+(we never officially supported or documented that).
+
+Make sure ofpart doesn't attempt to parse above.

++
++description: |
++ Linksys devices based on Broadcom Northstar architecture often use two
++ firmware partitions. One is used for regular booting, the other is treated as
++ fallback.
++
++ This binding allows defining all fixed partitions and marking those containing
++ firmware. System can use that information e.g. for booting or flashing
++ purposes.

+Subject: [PATCH] net: implement threaded-able napi poll loop support
+
+This patch allows running each napi poll loop inside its own
+kernel thread.
+The kthread is created during netif_napi_add() if dev->threaded
+is set. And threaded mode is enabled in napi_enable(). We will
+provide a way to set dev->threaded and enable threaded mode
+without a device up/down in the following patch.
+
+Once that threaded mode is enabled and the kthread is
+started, napi_schedule() will wake-up such thread instead
+of scheduling the softirq.
+
+The threaded poll loop behaves quite likely the net_rx_action,
+but it does not have to manipulate local irqs and uses
+an explicit scheduling point based on netdev_budget.

+Subject: [PATCH] net: add sysfs attribute to control napi threaded mode
+
+This patch adds a new sysfs attribute to the network device class.
+Said attribute provides a per-device control to enable/disable the
+threaded mode for all the napi instances of the given network device,
+without the need for a device up/down.
+User sets it to 1 or 0 to enable or disable threaded mode.
+Note: when switching between threaded and the current softirq based mode
+for a napi instance, it will not immediately take effect if the napi is
+currently being polled. The mode switch will happen for the next time
+napi_schedule() is called.

+Subject: [PATCH] net: fix race between napi kthread mode and busy poll
+
+Currently, napi_thread_wait() checks for NAPI_STATE_SCHED bit to
+determine if the kthread owns this napi and could call napi->poll() on
+it. However, if socket busy poll is enabled, it is possible that the
+busy poll thread grabs this SCHED bit (after the previous napi->poll()
+invokes napi_complete_done() and clears SCHED bit) and tries to poll
+on the same napi. napi_disable() could grab the SCHED bit as well.
+This patch tries to fix this race by adding a new bit
+NAPI_STATE_SCHED_THREADED in napi->state. This bit gets set in
+____napi_schedule() if the threaded mode is enabled, and gets cleared
+in napi_complete_done(), and we only poll the napi in kthread if this
+bit is set. This helps distinguish the ownership of the napi between
+kthread and other scenarios and fixes the race issue.

+Subject: [PATCH] net: fix hangup on napi_disable for threaded napi
+
+napi_disable() is subject to an hangup, when the threaded
+mode is enabled and the napi is under heavy traffic.
+
+If the relevant napi has been scheduled and the napi_disable()
+kicks in before the next napi_threaded_wait() completes - so
+that the latter quits due to the napi_disable_pending() condition,
+the existing code leaves the NAPI_STATE_SCHED bit set and the
+napi_disable() loop waiting for such bit will hang.
+
+This patch addresses the issue by dropping the NAPI_STATE_DISABLE
+bit test in napi_thread_wait(). The later napi_threaded_poll()
+iteration will take care of clearing the NAPI_STATE_SCHED.
+
+This also addresses a related problem reported by Jakub:
+before this patch a napi_disable()/napi_enable() pair killed
+the napi thread, effectively disabling the threaded mode.
+On the patched kernel napi_disable() simply stops scheduling
+the relevant thread.
+
+v1 -> v2:
+ - let the main napi_thread_poll() loop clear the SCHED bit

+Subject: [PATCH] netfilter: flowtable: separate replace, destroy and
+ stats to different workqueues
+
+Currently the flow table offload replace, destroy and stats work items are
+executed on a single workqueue. As such, DESTROY and STATS commands may
+be backloged after a burst of REPLACE work items. This scenario can bloat
+up memory and may cause active connections to age.
+
+Instatiate add, del and stats workqueues to avoid backlogs of non-dependent
+actions. Provide sysfs control over the workqueue attributes, allowing
+userspace applications to control the workqueue cpumask.

+Subject: [PATCH] net: resolve forwarding path from virtual netdevice and
+ HW destination address
+
+This patch adds dev_fill_forward_path() which resolves the path to reach
+the real netdevice from the IP forwarding side. This function takes as
+input the netdevice and the destination hardware address and it walks
+down the devices calling .ndo_fill_forward_path() for each device until
+the real device is found.
+
+For instance, assuming the following topology:
+
+ IP forwarding
+ / \
+ br0 eth0
+ / \
+ eth1 eth2
+ .
+ .
+ .
+ ethX
+ ab:cd:ef:ab:cd:ef
+
+where eth1 and eth2 are bridge ports and eth0 provides WAN connectivity.
+ethX is the interface in another box which is connected to the eth1
+bridge port.
+
+For packets going through IP forwarding to br0 whose destination MAC
+address is ab:cd:ef:ab:cd:ef, dev_fill_forward_path() provides the
+following path:
+
+ br0 -> eth1
+
+.ndo_fill_forward_path for br0 looks up at the FDB for the bridge port
+from the destination MAC address to get the bridge port eth1.

+ actions in bridge devices
+
+Depending on the VLAN settings of the bridge and the port, the bridge can
+either add or remove a tag. When vlan filtering is enabled, the fdb lookup
+also needs to know the VLAN tag/proto for the destination address
+To provide this, keep track of the stack of VLAN tags for the path in the
+lookup context

+
+Obtain the ingress device in the tuple from the route in the reply

+
+Fall back to use the ingress device that the IP forwarding route
+provides if:
+
+- dev_fill_forward_path() finds no real ingress device.
+- the ingress device that is obtained is not part of the flowtable

+- this route has a xfrm policy.

+Subject: [PATCH] netfilter: flowtable: use dev_fill_forward_path() to
+ obtain egress device
+
+The egress device in the tuple is obtained from route. Use
+dev_fill_forward_path() instead to provide the real egress device for
+this flow whenever this is available.
+
+The new FLOW_OFFLOAD_XMIT_DIRECT type uses dev_queue_xmit() to transmit
+ethernet frames. Cache the source and destination hardware address to
+use dev_queue_xmit() to transfer packets.
+
+The FLOW_OFFLOAD_XMIT_DIRECT replaces FLOW_OFFLOAD_XMIT_NEIGH if
+dev_fill_forward_path() finds a direct transmit path.
+
+In case of topology updates, if peer is moved to different bridge port,
+the connection will time out, reconnect will result in a new entry with
+the correct path. Snooping fdb updates would allow for cleaning up stale
+flowtable entries.

+Subject: [PATCH] netfilter: flowtable: add vlan support
+
+Add the vlan id and protocol to the flow tuple to uniquely identify
+flows from the receive path. For the transmit path, dev_hard_header() on
+the vlan device push the headers. This patch includes support for two
+vlan headers (QinQ) from the ingress path.
+
+Add a generic encap field to the flowtable entry which stores the
+protocol and the tag id. This allows to reuse these fields in the PPPoE
+support coming in a later patch.

+This patch adds two new tests to cover bridge and vlan support:
+
+- Add a bridge device to the Router1 (nsr1) container and attach the
+ veth0 device to the bridge. Set the IP address to the bridge device
+ to exercise the bridge forwarding path.
+
+- Add vlan encapsulation between to the bridge device in the Router1 and
+ one of the sender containers (ns1).

+
+When the flow tuple xmit_type is set to FLOW_OFFLOAD_XMIT_DIRECT, the
+dst_cache pointer is not valid, and the h_source/h_dest/ifidx out fields
+need to be used.
+
+This patch also adds the FLOW_ACTION_VLAN_PUSH action to pass the VLAN
+tag to the driver.

+ hardware offload is enabled
+
+If there is a forward path to reach an ethernet device and hardware
+offload is enabled, then use the direct xmit path.
+
+Moreover, store the real device in the direct xmit path info since
+software datapath uses dev_hard_header() to push the layer encapsulation
+headers while hardware offload refers to the real device.

+The dsa infrastructure provides a well-defined hierarchy of devices,
+pass up the call to set up the flow block to the master device. From the

+Similarly, the flowtable definition in the ruleset refers to the dsa

+ Netfilter's flowtable infrastructure
+ ====================================
+
+-This documentation describes the software flowtable infrastructure available in
+-Netfilter since Linux kernel 4.16.
++This documentation describes the Netfilter flowtable infrastructure which allows
++you to define a fastpath through the flowtable datapath. This infrastructure
++also provides hardware offload support. The flowtable supports for the layer 3
++IPv4 and IPv6 and the layer 4 TCP and UDP protocols.
+
+ Overview
+ --------
+
+-Initial packets follow the classic forwarding path, once the flow enters the
+-established state according to the conntrack semantics (ie. we have seen traffic
+-in both directions), then you can decide to offload the flow to the flowtable
+-from the forward chain via the 'flow offload' action available in nftables.
+-
+-Packets that find an entry in the flowtable (ie. flowtable hit) are sent to the
+-output netdevice via neigh_xmit(), hence, they bypass the classic forwarding
+-path (the visible effect is that you do not see these packets from any of the
+-netfilter hooks coming after the ingress). In case of flowtable miss, the packet
+-follows the classic forward path.
+-
+-The flowtable uses a resizable hashtable, lookups are based on the following
+-7-tuple selectors: source, destination, layer 3 and layer 4 protocols, source
+-and destination ports and the input interface (useful in case there are several
+-conntrack zones in place).
+-
+-Flowtables are populated via the 'flow offload' nftables action, so the user can
+-selectively specify what flows are placed into the flow table. Hence, packets
+-follow the classic forwarding path unless the user explicitly instruct packets
+-to use this new alternative forwarding path via nftables policy.
++Once the first packet of the flow successfully goes through the IP forwarding
++path, from the second packet on, you might decide to offload the flow to the
++flowtable through your ruleset. The flowtable infrastructure provides a rule
++action that allows you to specify when to add a flow to the flowtable.
++
++A packet that finds a matching entry in the flowtable (ie. flowtable hit) is
++transmitted to the output netdevice via neigh_xmit(), hence, packets bypass the
++classic IP forwarding path (the visible effect is that you do not see these
++packets from any of the Netfilter hooks coming after ingress). In case that
++there is no matching entry in the flowtable (ie. flowtable miss), the packet
++follows the classic IP forwarding path.
++
++The flowtable uses a resizable hashtable. Lookups are based on the following
++n-tuple selectors: layer 2 protocol encapsulation (VLAN and PPPoE), layer 3
++source and destination, layer 4 source and destination ports and the input
++interface (useful in case there are several conntrack zones in place).
++
++The 'flow add' action allows you to populate the flowtable, the user selectively
++specifies what flows are placed into the flowtable. Hence, packets follow the
++classic IP forwarding path unless the user explicitly instruct flows to use this
++new alternative forwarding path via policy.
+
+-This is represented in Fig.1, which describes the classic forwarding path
+-including the Netfilter hooks and the flowtable fastpath bypass.

+ The flowtable entry also stores the NAT configuration, so all packets are
+-mangled according to the NAT policy that matches the initial packets that went

+-path given that the transport selectors are missing, therefore flowtable lookup

++
++
++Layer 2 encapsulation
++---------------------
++
++Since Linux kernel 5.13, the flowtable infrastructure discovers the real
++netdevice behind VLAN and PPPoE netdevices. The flowtable software datapath
++parses the VLAN and PPPoE layer 2 headers to extract the ethertype and the
++VLAN ID / PPPoE session ID which are used for the flowtable lookups. The
++flowtable datapath also deals with layer 2 decapsulation.
++
++You do not need to add the PPPoE and the VLAN devices to your flowtable,
++instead the real device is sufficient for the flowtable to track your flows.
++
++Bridge and IP forwarding
++------------------------
++
++Since Linux kernel 5.13, you can add bridge ports to the flowtable. The
++flowtable infrastructure discovers the topology behind the bridge device. This
++allows the flowtable to define a fastpath bypass between the bridge ports
++(represented as eth1 and eth2 in the example figure below) and the gateway
++device (represented as eth0) in your switch/router.
++
++::
++ fastpath bypass
++ .-------------------------.
++ / \
++ | IP forwarding |
++ | / \ \/
++ | br0 eth0 ..... eth0
++ . / \ *host B*
++ -> eth1 eth2
++ . *switch/router*
++ .
++ .
++ eth0
++ *host A*
++
++The flowtable infrastructure also supports for bridge VLAN filtering actions
++such as PVID and untagged. You can also stack a classic VLAN device on top of
++your bridge port.
++
++If you would like that your flowtable defines a fastpath between your bridge
++ports and your IP forwarding path, you have to add your bridge ports (as
++represented by the real netdevice) to your flowtable definition.
++
++Counters
++--------
++
++The flowtable can synchronize packet and byte counters with the existing
++connection tracking entry by specifying the counter statement in your flowtable
++definition, e.g.
++
++::
++ table inet x {
++ flowtable f {
++ hook ingress priority 0; devices = { eth0, eth1 };
++ counter
++ }
++ ...
++ }
++
++Counter support is available since Linux kernel 5.7.
++
++Hardware offload
++----------------
++
++If your network device provides hardware offload support, you can turn it on by
++means of the 'offload' flag in your flowtable definition, e.g.
++
++::
++ table inet x {
++ flowtable f {
++ hook ingress priority 0; devices = { eth0, eth1 };
++ flags offload;
++ }
++ ...
++ }
++
++There is a workqueue that adds the flows to the hardware. Note that a few
++packets might still run over the flowtable software path until the workqueue has
++a chance to offload the flow to the network device.
++
++You can identify hardware offloaded flows through the [HW_OFFLOAD] tag when
++listing your connection tracking table. Please, note that the [OFFLOAD] tag
++refers to the software offload mode, so there is a distinction between [OFFLOAD]
++which refers to the software flowtable fastpath and [HW_OFFLOAD] which refers
++to the hardware offload datapath being used by the flow.
++
++The flowtable hardware offload infrastructure also supports for the DSA
++(Distributed Switch Architecture).
++
++Limitations
++-----------
++
++The flowtable behaves like a cache. The flowtable entries might get stale if
++either the destination MAC address or the egress netdevice that is used for
++transmission changes.
++
++This might be a problem if:
++
++- You run the flowtable in software mode and you combine bridge and IP
++ forwarding in your setup.
++- Hardware offload is enabled.

+
+The intention is for the loop to timeout if the body does not succeed.
+The current logic calls time_is_before_jiffies(timeout) which is false
+until after the timeout, so the loop body never executes.
+
+Fix by using readl_poll_timeout as a more standard and less error-prone
+solution.

+
+Issue was traffic problems after a while with increased ping times if
+flow offload is active. It turns out that key_offset with cookie is
+needed in rhashtable_params but was re-assigned to head_offset.
+Fix the assignment.

+usleep_range often ends up sleeping much longer than the 10-20us provided

+
+Move dst_check() to the garbage collector path. Stale routes trigger the
+flow entry teardown state which makes affected flows go back to the
+classic forwarding path to re-evaluate flow offloading.
+
+IPv6 requires the dst cookie to work, store it in the flow_tuple,

+Subject: [PATCH] net: phy: at803x: select correct page on config init
+
+The Atheros AR8031 and AR8033 expose different registers for SGMII/Fiber
+as well as the copper side of the PHY depending on the BT_BX_REG_SEL bit
+in the chip configure register.
+
+The driver assumes the copper side is selected on probe, but this might
+not be the case depending which page was last selected by the
+bootloader. Notably, Ubiquiti UniFi bootloaders show this behavior.
+
+Select the copper page when probing to circumvent this.

+Subject: [PATCH] net: phy: at803x: fix probe error if copper page is selected
+
+The commit c329e5afb42f ("net: phy: at803x: select correct page on
+config init") selects the copper page during probe. This fails if the
+copper page was already selected. In this case, the value of the copper
+page (which is 1) is propagated through phy_restore_page() and is
+finally returned for at803x_probe(). Fix it, by just using the
+at803x_page_write() directly.
+
+Also in case of an error, the regulator is not disabled and leads to a
+WARN_ON() when the probe fails. This couldn't happen before, because
+at803x_parse_dt() was the last call in at803x_probe(). It is hard to
+see, that the parse_dt() actually enables the regulator. Thus move the
+regulator_enable() to the probe function and undo it in case of an
+error.

+From: Ivan Bornyakov <i.bornyakov@metrotek.ru>
+Date: Thu, 12 Aug 2021 16:42:56 +0300
+Subject: [PATCH] net: phy: marvell: add SFP support for 88E1510
+
+Add support for SFP cages connected to the Marvell 88E1512 transceiver.
+88E1512 supports for SGMII/1000Base-X/100Base-FX media type with RGMII
+on system interface. Configure PHY to appropriate mode depending on the
+type of SFP inserted. On SFP removal configure PHY to the RGMII-copper
+mode so RJ-45 port can still work.

+Subject: [PATCH] net: dsa: automatically bring up DSA master when opening user
+ port
+
+DSA wants the master interface to be open before the user port is due to
+historical reasons. The promiscuity of interfaces that are down used to
+have issues, as referenced Lennert Buytenhek in commit df02c6ff2e39
+("dsa: fix master interface allmulti/promisc handling").
+
+The bugfix mentioned there, commit b6c40d68ff64 ("net: only invoke
+dev->change_rx_flags when device is UP"), was basically a "don't do
+that" approach to working around the promiscuity while down issue.
+
+Further work done by Vlad Yasevich in commit d2615bf45069 ("net: core:
+Always propagate flag changes to interfaces") has resolved the
+underlying issue, and it is strictly up to the DSA and 8021q drivers
+now, it is no longer mandated by the networking core that the master
+interface must be up when changing its promiscuity.
+
+From DSA's point of view, deciding to error out in dsa_slave_open
+because the master isn't up is
+(a) a bad user experience and
+(b) knocking at an open door.
+Even if there still was an issue with promiscuity while down, DSA could
+still just open the master and avoid it.
+
+Doing it this way has the additional benefit that user space can now
+remove DSA-specific workarounds, like systemd-networkd with BindCarrier:
+https://github.com/systemd/systemd/issues/7478
+
+And we can finally remove one of the 2 bullets in the "Common pitfalls
+using DSA setups" chapter.
+
+Tested with two cascaded DSA switches:

+Subject: [PATCH] net: bridge: notify switchdev of disappearance of old FDB
+ entry upon migration
+
+Currently the bridge emits atomic switchdev notifications for
+dynamically learnt FDB entries. Monitoring these notifications works
+wonders for switchdev drivers that want to keep their hardware FDB in
+sync with the bridge's FDB.
+
+For example station A wants to talk to station B in the diagram below,
+and we are concerned with the behavior of the bridge on the DUT device:
+
+ DUT
+ +-------------------------------------+
+ | br0 |
+ | +------+ +------+ +------+ +------+ |
+ | | | | | | | | | |
+ | | swp0 | | swp1 | | swp2 | | eth0 | |
+ +-------------------------------------+
+ | | |
+ Station A | |
+ | |
+ +--+------+--+ +--+------+--+
+ | | | | | | | |
+ | | swp0 | | | | swp0 | |
+ Another | +------+ | | +------+ | Another
+ switch | br0 | | br0 | switch
+ | +------+ | | +------+ |
+ | | | | | | | |
+ | | swp1 | | | | swp1 | |
+ +--+------+--+ +--+------+--+
+ |
+ Station B
+
+Interfaces swp0, swp1, swp2 are handled by a switchdev driver that has
+the following property: frames injected from its control interface bypass
+the internal address analyzer logic, and therefore, this hardware does
+not learn from the source address of packets transmitted by the network
+stack through it. So, since bridging between eth0 (where Station B is
+attached) and swp0 (where Station A is attached) is done in software,
+the switchdev hardware will never learn the source address of Station B.
+So the traffic towards that destination will be treated as unknown, i.e.
+flooded.
+
+This is where the bridge notifications come in handy. When br0 on the
+DUT sees frames with Station B's MAC address on eth0, the switchdev
+driver gets these notifications and can install a rule to send frames
+towards Station B's address that are incoming from swp0, swp1, swp2,
+only towards the control interface. This is all switchdev driver private
+business, which the notification makes possible.
+
+All is fine until someone unplugs Station B's cable and moves it to the
+other switch:
+
+ DUT
+ +-------------------------------------+
+ | br0 |
+ | +------+ +------+ +------+ +------+ |
+ | | | | | | | | | |
+ | | swp0 | | swp1 | | swp2 | | eth0 | |
+ +-------------------------------------+
+ | | |
+ Station A | |
+ | |
+ +--+------+--+ +--+------+--+
+ | | | | | | | |
+ | | swp0 | | | | swp0 | |
+ Another | +------+ | | +------+ | Another
+ switch | br0 | | br0 | switch
+ | +------+ | | +------+ |
+ | | | | | | | |
+ | | swp1 | | | | swp1 | |
+ +--+------+--+ +--+------+--+
+ |
+ Station B
+
+Luckily for the use cases we care about, Station B is noisy enough that
+the DUT hears it (on swp1 this time). swp1 receives the frames and
+delivers them to the bridge, who enters the unlikely path in br_fdb_update
+of updating an existing entry. It moves the entry in the software bridge
+to swp1 and emits an addition notification towards that.
+
+As far as the switchdev driver is concerned, all that it needs to ensure
+is that traffic between Station A and Station B is not forever broken.
+If it does nothing, then the stale rule to send frames for Station B
+towards the control interface remains in place. But Station B is no
+longer reachable via the control interface, but via a port that can
+offload the bridge port learning attribute. It's just that the port is
+prevented from learning this address, since the rule overrides FDB
+updates. So the rule needs to go. The question is via what mechanism.
+
+It sure would be possible for this switchdev driver to keep track of all
+addresses which are sent to the control interface, and then also listen
+for bridge notifier events on its own ports, searching for the ones that
+have a MAC address which was previously sent to the control interface.
+But this is cumbersome and inefficient. Instead, with one small change,
+the bridge could notify of the address deletion from the old port, in a
+symmetrical manner with how it did for the insertion. Then the switchdev
+driver would not be required to monitor learn/forget events for its own
+ports. It could just delete the rule towards the control interface upon
+bridge entry migration. This would make hardware address learning be
+possible again. Then it would take a few more packets until the hardware
+and software FDB would be in sync again.

+Subject: [PATCH] net: dsa: don't use switchdev_notifier_fdb_info in
+ dsa_switchdev_event_work
+
+Currently DSA doesn't add FDB entries on the CPU port, because it only
+does so through switchdev, which is associated with a net_device, and
+there are none of those for the CPU port.
+
+But actually FDB addresses on the CPU port have some use cases of their
+own, if the switchdev operations are initiated from within the DSA
+layer. There is just one problem with the existing code: it passes a
+structure in dsa_switchdev_event_work which was retrieved directly from
+switchdev, so it contains a net_device. We need to generalize the
+contents to something that covers the CPU port as well: the "ds, port"
+tuple is fine for that.
+
+Note that the new procedure for notifying the successful FDB offload is
+inspired from the rocker model.
+
+Also, nothing was being done if added_by_user was false. Let's check for
+that a lot earlier, and don't actually bother to schedule the worker
+for nothing.

+
+Right now, the following would happen for a switch driver that does not

+
+dsa_slave_switchdev_event returns NOTIFY_OK and schedules:
+-> dsa_slave_switchdev_event_work
+ -> dsa_port_fdb_add
+ -> dsa_port_notify(DSA_NOTIFIER_FDB_ADD)
+ -> dsa_switch_fdb_add
+ -> if (!ds->ops->port_fdb_add) return -EOPNOTSUPP;
+ -> an error is printed with dev_dbg, and
+ dsa_fdb_offload_notify(switchdev_work) is not called.
+
+We can avoid scheduling the worker for nothing and say NOTIFY_DONE.
+Because we don't call dsa_fdb_offload_notify, the static FDB entry will
+remain just in the software bridge.

+Subject: [PATCH] net: dsa: listen for SWITCHDEV_{FDB,DEL}_ADD_TO_DEVICE on
+ foreign bridge neighbors
+
+Some DSA switches (and not only) cannot learn source MAC addresses from
+packets injected from the CPU. They only perform hardware address
+learning from inbound traffic.
+
+This can be problematic when we have a bridge spanning some DSA switch
+ports and some non-DSA ports (which we'll call "foreign interfaces" from
+DSA's perspective).
+
+There are 2 classes of problems created by the lack of learning on
+CPU-injected traffic:
+- excessive flooding, due to the fact that DSA treats those addresses as
+ unknown
+- the risk of stale routes, which can lead to temporary packet loss
+
+To illustrate the second class, consider the following situation, which
+is common in production equipment (wireless access points, where there
+is a WLAN interface and an Ethernet switch, and these form a single
+bridging domain).
+
+ AP 1:
+ +------------------------------------------------------------------------+
+ | br0 |
+ +------------------------------------------------------------------------+
+ +------------+ +------------+ +------------+ +------------+ +------------+
+ | swp0 | | swp1 | | swp2 | | swp3 | | wlan0 |
+ +------------+ +------------+ +------------+ +------------+ +------------+
+ | ^ ^
+ | | |
+ | | |
+ | Client A Client B
+ |
+ |
+ |
+ +------------+ +------------+ +------------+ +------------+ +------------+
+ | swp0 | | swp1 | | swp2 | | swp3 | | wlan0 |
+ +------------+ +------------+ +------------+ +------------+ +------------+
+ +------------------------------------------------------------------------+
+ | br0 |
+ +------------------------------------------------------------------------+
+ AP 2
+
+- br0 of AP 1 will know that Clients A and B are reachable via wlan0
+- the hardware fdb of a DSA switch driver today is not kept in sync with
+ the software entries on other bridge ports, so it will not know that
+ clients A and B are reachable via the CPU port UNLESS the hardware
+ switch itself performs SA learning from traffic injected from the CPU.
+ Nonetheless, a substantial number of switches don't.
+- the hardware fdb of the DSA switch on AP 2 may autonomously learn that
+ Client A and B are reachable through swp0. Therefore, the software br0
+ of AP 2 also may or may not learn this. In the example we're
+ illustrating, some Ethernet traffic has been going on, and br0 from AP
+ 2 has indeed learnt that it can reach Client B through swp0.
+
+One of the wireless clients, say Client B, disconnects from AP 1 and
+roams to AP 2. The topology now looks like this:
+
+ AP 1:
+ +------------------------------------------------------------------------+
+ | br0 |
+ +------------------------------------------------------------------------+
+ +------------+ +------------+ +------------+ +------------+ +------------+
+ | swp0 | | swp1 | | swp2 | | swp3 | | wlan0 |
+ +------------+ +------------+ +------------+ +------------+ +------------+
+ | ^
+ | |
+ | Client A
+ |
+ |
+ | Client B
+ | |
+ | v
+ +------------+ +------------+ +------------+ +------------+ +------------+
+ | swp0 | | swp1 | | swp2 | | swp3 | | wlan0 |
+ +------------+ +------------+ +------------+ +------------+ +------------+
+ +------------------------------------------------------------------------+
+ | br0 |
+ +------------------------------------------------------------------------+
+ AP 2
+
+- br0 of AP 1 still knows that Client A is reachable via wlan0 (no change)
+- br0 of AP 1 will (possibly) know that Client B has left wlan0. There
+ are cases where it might never find out though. Either way, DSA today
+ does not process that notification in any way.
+- the hardware FDB of the DSA switch on AP 1 may learn autonomously that
+ Client B can be reached via swp0, if it receives any packet with
+ Client 1's source MAC address over Ethernet.
+- the hardware FDB of the DSA switch on AP 2 still thinks that Client B
+ can be reached via swp0. It does not know that it has roamed to wlan0,
+ because it doesn't perform SA learning from the CPU port.
+
+Now Client A contacts Client B.
+AP 1 routes the packet fine towards swp0 and delivers it on the Ethernet
+segment.
+AP 2 sees a frame on swp0 and its fdb says that the destination is swp0.
+Hairpinning is disabled => drop.
+
+This problem comes from the fact that these switches have a 'blind spot'
+for addresses coming from software bridging. The generic solution is not
+to assume that hardware learning can be enabled somehow, but to listen
+to more bridge learning events. It turns out that the bridge driver does
+learn in software from all inbound frames, in __br_handle_local_finish.
+A proper SWITCHDEV_FDB_ADD_TO_DEVICE notification is emitted for the
+addresses serviced by the bridge on 'foreign' interfaces. The software
+bridge also does the right thing on migration, by notifying that the old
+entry is deleted, so that does not need to be special-cased in DSA. When
+it is deleted, we just need to delete our static FDB entry towards the
+CPU too, and wait.
+
+The problem is that DSA currently only cares about SWITCHDEV_FDB_ADD_TO_DEVICE
+events received on its own interfaces, such as static FDB entries.
+
+Luckily we can change that, and DSA can listen to all switchdev FDB
+add/del events in the system and figure out if those events were emitted
+by a bridge that spans at least one of DSA's own ports. In case that is
+true, DSA will also offload that address towards its own CPU port, in
+the eventuality that there might be bridge clients attached to the DSA
+switch who want to talk to the station connected to the foreign
+interface.
+
+In terms of implementation, we need to keep the fdb_info->added_by_user
+check for the case where the switchdev event was targeted directly at a
+DSA switch port. But we don't need to look at that flag for snooped
+events. So the check is currently too late, we need to move it earlier.
+This also simplifies the code a bit, since we avoid uselessly allocating
+and freeing switchdev_work.
+
+We could probably do some improvements in the future. For example,
+multi-bridge support is rudimentary at the moment. If there are two
+bridges spanning a DSA switch's ports, and both of them need to service
+the same MAC address, then what will happen is that the migration of one
+of those stations will trigger the deletion of the FDB entry from the
+CPU port while it is still used by other bridge. That could be improved
+with reference counting but is left for another time.
+
+This behavior needs to be enabled at driver level by setting
+ds->assisted_learning_on_cpu_port = true. This is because we don't want
+to inflict a potential performance penalty (accesses through
+MDIO/I2C/SPI are expensive) to hardware that really doesn't need it
+because address learning on the CPU port works there.

+
+A recent change to MIPS ralink reset logic made it so mt7530 actually
+resets the switch on platforms such as mt7621 (where bit 2 is the reset
+line for the switch). That exposed an issue where the switch would not
+function properly in TRGMII mode after a reset.
+
+Reconfigure core clock in TRGMII mode to fix the issue.
+
+Tested on Ubiquiti ER-X (MT7621) with TRGMII mode enabled.

+Subject: of: net: pass the dst buffer to of_get_mac_address()
+
+of_get_mac_address() returns a "const void*" pointer to a MAC address.
+Lately, support to fetch the MAC address by an NVMEM provider was added.
+But this will only work with platform devices. It will not work with
+PCI devices (e.g. of an integrated root complex) and esp. not with DSA
+ports.
+
+There is an of_* variant of the nvmem binding which works without
+devices. The returned data of a nvmem_cell_read() has to be freed after
+use. On the other hand the return of_get_mac_address() points to some
+static data without a lifetime. The trick for now, was to allocate a
+device resource managed buffer which is then returned. This will only
+work if we have an actual device.
+
+Change it, so that the caller of of_get_mac_address() has to supply a
+buffer where the MAC address is written to. Unfortunately, this will
+touch all drivers which use the of_get_mac_address().
+
+Usually the code looks like:
+
+ const char *addr;
+ addr = of_get_mac_address(np);
+ if (!IS_ERR(addr))
+ ether_addr_copy(ndev->dev_addr, addr);
+
+This can then be simply rewritten as:
+
+ of_get_mac_address(np, ndev->dev_addr);
+
+Sometimes is_valid_ether_addr() is used to test the MAC address.
+of_get_mac_address() already makes sure, it just returns a valid MAC
+address. Thus we can just test its return code. But we have to be
+careful if there are still other sources for the MAC address before the
+of_get_mac_address(). In this case we have to keep the
+is_valid_ether_addr() call.
+
+The following coccinelle patch was used to convert common cases to the
+new style. Afterwards, I've manually gone over the drivers and fixed the
+return code variable: either used a new one or if one was already
+available use that. Mansour Moufid, thanks for that coccinelle patch!

+From: Michael Walle <michael@walle.cc>
+Date: Mon, 12 Apr 2021 19:47:18 +0200
+Subject: of: net: fix of_get_mac_addr_nvmem() for non-platform devices
+
+of_get_mac_address() already supports fetching the MAC address by an
+nvmem provider. But until now, it was just working for platform devices.
+Esp. it was not working for DSA ports and PCI devices. It gets more
+common that PCI devices have a device tree binding since SoCs contain
+integrated root complexes.
+
+Use the nvmem of_* binding to fetch the nvmem cells by a struct
+device_node. We still have to try to read the cell by device first
+because there might be a nvmem_cell_lookup associated with that device.

+Subject: [PATCH] net: bgmac-bcma: handle deferred probe error due to
+ mac-address
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Due to the inclusion of nvmem handling into the mac-address getter
+function of_get_mac_address() by
+commit d01f449c008a ("of_net: add NVMEM support to of_get_mac_address")
+it is now possible to get a -EPROBE_DEFER return code. Which did cause
+bgmac to assign a random ethernet address.
+
+This exact issue happened on my Meraki MR32. The nvmem provider is
+an EEPROM (at24c64) which gets instantiated once the module
+driver is loaded... This happens once the filesystem becomes available.
+
+With this patch, bgmac_probe() will propagate the -EPROBE_DEFER error.
+Then the driver subsystem will reschedule the probe at a later time.

+Subject: [PATCH] net: bgmac-platform: handle mac-address deferral
+
+This patch is a replication of Christian Lamparter's "net: bgmac-bcma:
+handle deferred probe error due to mac-address" patch for the
+bgmac-platform driver [1].
+
+As is the case with the bgmac-bcma driver, this change is to cover the
+scenario where the MAC address cannot yet be discovered due to reliance
+on an nvmem provider which is yet to be instantiated, resulting in a
+random address being assigned that has to be manually overridden.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+1. Use info from DT if available
+
+It allows describing for example a fixed link. It's more accurate than
+just guessing there may be one (depending on a chipset).
+
+2. Verify PHY ID before trying to connect PHY
+
+PHY addr 0x1e (30) is special in Broadcom routers and means a switch
+connected as MDIO devices instead of a real PHY. Don't try connecting to
+it.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Check ethernet controller DT node for "mdio" subnode and use it with
+of_mdiobus_register() when present. That allows specifying MDIO and its
+PHY devices in a standard DT based way.
+
+This is required for BCM53573 SoC support. That family is sometimes
+called Northstar (by marketing?) but is quite different from it. It uses
+different CPU(s) and many different hw blocks.
+
+One of shared blocks in BCM53573 is Ethernet controller. Switch however
+is not SRAB accessible (as it Northstar) but is MDIO attached.

+
+qca8k_rmw can fail. Rework any user to handle error values and
+correctly return. Change qca8k_rmw to return the error code or 0 instead
+of the reg value. The reg returned by qca8k_rmw wasn't used anywhere,
+so this doesn't cause any functional change.

+Subject: [PATCH] net: dsa: qca8k: make rgmii delay configurable
+
+The legacy qsdk code used a different delay instead of the max value.
+Qsdk use 1 ns for rx and 2 ns for tx. Make these values configurable
+using the standard rx/tx-internal-delay-ps ethernet binding and apply
+qsdk values by default. The connected gmac doesn't add any delay so no
+additional delay is added to tx/rx.
+On this switch the delay is actually in ns so value should be in the
+1000 order. Any value converted from ps to ns by dividing it by 1000
+as the switch max value for delay is 3ns.

+
+Clear MDIO_MASTER_EN bit from MDIO_MASTER_CTRL after read/write
+operation. The MDIO_MASTER_EN bit is not reset after read/write
+operation and the next operation can be wrongly interpreted by the
+switch as a mdio operation. This cause a production of wrong/garbage
+data from the switch and underfined bheavior. (random port drop,
+unplugged port flagged with link up, wrong port speed)
+Also on driver remove the MASTER_CTRL can be left set and cause the
+malfunction of any next driver using the mdio device.

+
+The witch require some extra delay after setting page or the next
+read/write can use still use the old page. Add a delay after the
+set_page function to address this as it's done in QSDK legacy driver.
+Some timeouts were notice with VLAN and phy function, enlarge the
+mdio busy wait timeout to fix these problems.

+Subject: [PATCH] net: dsa: qca8k: add support for internal phy and internal
+ mdio
+
+Add support to setup_mdio_bus for internal phy declaration. Introduce a
+flag to use the legacy port phy mapping by default and use the direct
+mapping if a mdio node is detected in the switch node. Register a
+dedicated mdio internal mdio bus to address the different mapping
+between port and phy if the mdio node is detected.

+Subject: [PATCH] net: phy: add support for qca8k switch internal PHY in at803x
+
+Since the at803x share the same regs, it's assumed they are based on the
+same implementation. Make it part of the at803x PHY driver to skip
+having redudant code.
+Add initial support for qca8k internal PHYs. The internal PHYs requires
+special mmd and debug values to be set based on the switch revision
+passwd using the dev_flags. Supports output of idle, receive and eee_wake
+errors stats.
+Some debug values sets can't be translated as the documentation lacks any
+reference about them.

+
+Current return type of qca8k_mii_read32() and qca8k_read() are
+unsigned, it can't be negative, so the return value check is
+unuseful. For check the return value correctly, change return
+type of the read functions and add a output parameter to store

+Subject: [PATCH] net: dsa: qca8k: fix an endian bug in
+ qca8k_get_ethtool_stats()
+
+The "hi" variable is a u64 but the qca8k_read() writes to the top 32
+bits of it. That will work on little endian systems but it's a bit
+subtle. It's cleaner to make declare "hi" as a u32. We will still need
+to cast it when we shift it later on in the function but that's fine.

+Subject: [PATCH] net: dsa: b53: Do not force CPU to be always tagged
+
+Commit ca8931948344 ("net: dsa: b53: Keep CPU port as tagged in all
+VLANs") forced the CPU port to be always tagged in any VLAN membership.
+This was necessary back then because we did not support Broadcom tags
+for all configurations so the only way to differentiate tagged and
+untagged traffic while DSA_TAG_PROTO_NONE was used was to force the CPU
+port into being always tagged.
+
+With most configurations enabling Broadcom tags, especially after
+8fab459e69ab ("net: dsa: b53: Enable Broadcom tags for 531x5/539x
+families") we do not need to apply this unconditional force tagging of
+the CPU port in all VLANs.
+
+A helper function is introduced to faciliate the encapsulation of the
+specific condition requiring the CPU port to be tagged in all VLANs and
+the dsa_switch_ops::untag_bridge_pvid boolean is moved to when
+dsa_switch_ops::setup is called when we have already determined the
+tagging protocol we will be using.

+ port
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+On BCM5301x port 8 requires a fixed link when used.
+
+Years ago when b53 was an OpenWrt downstream driver (with configuration
+based on sometimes bugged NVRAM) there was a need for a fixup. In case
+of forcing fixed link for (incorrectly specified) port 5 the code had to
+actually setup port 8 link.
+
+For upstream b53 driver with setup based on DT there is no need for that
+workaround. In DT we have and require correct ports setup.

+Content-Type: text/plain; charset=UTF-8

+According to the Broadcom's reference driver flow control needs to be

+used). Current code makes it work only for the port 5. Use
+dsa_is_cpu_port() which solved that problem.

+Subject: [PATCH] net: dsa: don't set skb->offload_fwd_mark when not offloading
+ the bridge
+
+DSA has gained the recent ability to deal gracefully with upper
+interfaces it cannot offload, such as the bridge, bonding or team
+drivers. When such uppers exist, the ports are still in standalone mode
+as far as the hardware is concerned.
+
+But when we deliver packets to the software bridge in order for that to
+do the forwarding, there is an unpleasant surprise in that the bridge
+will refuse to forward them. This is because we unconditionally set
+skb->offload_fwd_mark = true, meaning that the bridge thinks the frames
+were already forwarded in hardware by us.
+
+Since dp->bridge_dev is populated only when there is hardware offload
+for it, but not in the software fallback case, let's introduce a new
+helper that can be called from the tagger data path which sets the
+skb->offload_fwd_mark accordingly to zero when there is no hardware
+offload for bridging. This lets the bridge forward packets back to other
+interfaces of our switch, if needed.

+Subject: net: phy: at803x: fix resume for QCA8327 phy
+
+From Documentation phy resume triggers phy reset and restart
+auto-negotiation. Add a dedicated function to wait reset to finish as
+it was notice a regression where port sometime are not reliable after a
+suspend/resume session. The reset wait logic is copied from phy_poll_reset.
+Add dedicated suspend function to use genphy_suspend only with QCA8337
+phy and set only additional debug settings for QCA8327. With more test
+it was reported that QCA8327 doesn't proprely support this mode and
+using this cause the unreliability of the switch ports, especially the
+malfunction of the port0.

+Subject: net: dsa: qca8k: add support for cpu port 6
+
+Currently CPU port is always hardcoded to port 0. This switch have 2 CPU
+ports. The original intention of this driver seems to be use the
+mac06_exchange bit to swap MAC0 with MAC6 in the strange configuration
+where device have connected only the CPU port 6. To skip the
+introduction of a new binding, rework the driver to address the
+secondary CPU port as primary and drop any reference of hardcoded port.
+With configuration of mac06 exchange, just skip the definition of port0
+and define the CPU port as a secondary. The driver will autoconfigure
+the switch to use that as the primary CPU port.

+Subject: net: dsa: qca8k: rework rgmii delay logic and scan for cpu port 6
+
+Future proof commit. This switch have 2 CPU ports and one valid
+configuration is first CPU port set to sgmii and second CPU port set to
+rgmii-id. The current implementation detects delay only for CPU port
+zero set to rgmii and doesn't count any delay set in a secondary CPU
+port. Drop the current delay scan function and move it to the sgmii
+parser function to generalize and implicitly add support for secondary
+CPU port set to rgmii-id. Introduce new logic where delay is enabled
+also with internal delay binding declared and rgmii set as PHY mode.

+QCA8328 switch is the bigger brother of the qca8327. Same regs different
+chip. Change the function to set the correct pin layout and introduce a
+new match_data to differentiate the 2 switch as they have the same ID
+and their internal PHY have the same ID.

+- "qca,qca8327": referenced as AR8327(N)-AL1A DR-QFN 148 pin package

+-
+-Optional properties:
+-
+-- reset-gpios: GPIO to be used to reset the whole device
+-- qca,ignore-power-on-sel: Ignore power on pin strapping to configure led open
+- drain or eeprom presence. This is needed for broken
+- devices that have wrong configuration or when the oem
+- decided to not use pin strapping and fallback to sw
+- regs.
+-- qca,led-open-drain: Set leds to open-drain mode. This requires the
+- qca,ignore-power-on-sel to be set or the driver will fail
+- to probe. This is needed if the oem doesn't use pin
+- strapping to set this mode and prefers to set it using sw
+- regs. The pin strapping related to led open drain mode is
+- the pin B68 for QCA832x and B49 for QCA833x
+-
+-Subnodes:
+-
+-The integrated switch subnode should be specified according to the binding
+-described in dsa/dsa.txt. If the QCA8K switch is connect to a SoC's external
+-mdio-bus each subnode describing a port needs to have a valid phandle
+-referencing the internal PHY it is connected to. This is because there's no
+-N:N mapping of port and PHY id.
+-To declare the internal mdio-bus configuration, declare a mdio node in the
+-switch node and declare the phandle for the port referencing the internal
+-PHY is connected to. In this config a internal mdio-bus is registered and
+-the mdio MASTER is used as communication.
+-
+-Don't use mixed external and internal mdio-bus configurations, as this is
+-not supported by the hardware.
+-
+-This switch support 2 CPU port. Normally and advised configuration is with
+-CPU port set to port 0. It is also possible to set the CPU port to port 6
+-if the device requires it. The driver will configure the switch to the defined
+-port. With both CPU port declared the first CPU port is selected as primary
+-and the secondary CPU ignored.
+-
+-A CPU port node has the following optional node:
+-
+-- fixed-link : Fixed-link subnode describing a link to a non-MDIO
+- managed entity. See
+- Documentation/devicetree/bindings/net/fixed-link.txt
+- for details.
+-- qca,sgmii-rxclk-falling-edge: Set the receive clock phase to falling edge.
+- Mostly used in qca8327 with CPU port 0 set to
+- sgmii.
+-- qca,sgmii-txclk-falling-edge: Set the transmit clock phase to falling edge.
+-- qca,sgmii-enable-pll : For SGMII CPU port, explicitly enable PLL, TX and RX
+- chain along with Signal Detection.
+- This should NOT be enabled for qca8327. If enabled with
+- qca8327 the sgmii port won't correctly init and an err
+- is printed.
+- This can be required for qca8337 switch with revision 2.
+- A warning is displayed when used with revision greater
+- 2.
+- With CPU port set to sgmii and qca8337 it is advised
+- to set this unless a communication problem is observed.
+-
+-For QCA8K the 'fixed-link' sub-node supports only the following properties:
+-
+-- 'speed' (integer, mandatory), to indicate the link speed. Accepted
+- values are 10, 100 and 1000
+-- 'full-duplex' (boolean, optional), to indicate that full duplex is
+- used. When absent, half duplex is assumed.

++description:
++ If the QCA8K switch is connect to an SoC's external mdio-bus, each subnode
++ describing a port needs to have a valid phandle referencing the internal PHY
++ it is connected to. This is because there is no N:N mapping of port and PHY
++ ID. To declare the internal mdio-bus configuration, declare an MDIO node in
++ the switch node and declare the phandle for the port, referencing the internal
++ PHY it is connected to. In this config, an internal mdio-bus is registered and
++ the MDIO master is used for communication. Mixed external and internal
++ mdio-bus configurations are not supported by the hardware.

+
+Fix delay settings applied to wrong cpu in parse_port_config. The delay
+values is set to the wrong index as the cpu_port_index is incremented
+too early. Start the cpu_port_index to -1 so the correct value is
+applied to address also the case with invalid phy mode and not available
+port.

+Some device set MAC06 exchange in the bootloader. This cause some
+problem as we don't support this strange mode and we just set the port6
+as the primary CPU port. With MAC06 exchange, PAD0 reg configure port6
+instead of port0. Add an extra check and explicitly disable MAC06 exchange
+to correctly configure the port PAD config.

+Subject: [PATCH] net: dsa: qca8k: fix internal delay applied to the wrong PAD
+ config
+
+With SGMII phy the internal delay is always applied to the PAD0 config.
+This is caused by the falling edge configuration that hardcode the reg
+to PAD0 (as the falling edge bits are present only in PAD0 reg)
+Move the delay configuration before the reg overwrite to correctly apply
+the delay.

+Subject: [PATCH] net: dsa: qca8k: fix MTU calculation
+
+qca8k has a global MTU, so its tracking the MTU per port to make sure
+that the largest MTU gets applied.
+Since it uses the frame size instead of MTU the driver MTU change function
+will then add the size of Ethernet header and checksum on top of MTU.
+
+The driver currently populates the per port MTU size as Ethernet frame
+length + checksum which equals 1518.
+
+The issue is that then MTU change function will go through all of the
+ports, find the largest MTU and apply the Ethernet header + checksum on
+top of it again, so for a desired MTU of 1500 you will end up with 1536.
+
+This is obviously incorrect, so to correct it populate the per port struct
+MTU with just the MTU and not include the Ethernet header + checksum size
+as those will be added by the MTU change function.

+Subject: net: dsa: qca8k: initial conversion to regmap helper
+
+Convert any qca8k set/clear/pool to regmap helper and add
+missing config to regmap_config struct.
+Read/write/rmw operation are reworked to use the regmap helper
+internally to keep the delta of this patch low. These additional
+function will then be dropped when the code split will be proposed.
+
+Ipq40xx SoC have the internal switch based on the qca8k regmap but use
+mmio for read/write/rmw operation instead of mdio.
+In preparation for the support of this internal switch, convert the
+driver to regmap API to later split the driver to common and specific

+Subject: [PATCH] net: dsa: mt7530: enable assisted learning on CPU port
+
+Consider the following bridge configuration, where bond0 is not
+offloaded:
+
+ +-- br0 --+
+ / / | \
+ / / | \
+ / | | bond0
+ / | | / \
+ swp0 swp1 swp2 swp3 swp4
+ . . .
+ . . .
+ A B C
+
+Address learning is enabled on offloaded ports (swp0~2) and the CPU
+port, so when client A sends a packet to C, the following will happen:
+
+1. The switch learns that client A can be reached at swp0.
+2. The switch probably already knows that client C can be reached at the
+ CPU port, so it forwards the packet to the CPU.
+3. The bridge core knows client C can be reached at bond0, so it
+ forwards the packet back to the switch.
+4. The switch learns that client A can be reached at the CPU port.
+5. The switch forwards the packet to either swp3 or swp4, according to
+ the packet's tag.
+
+That makes client A's MAC address flap between swp0 and the CPU port. If
+client B sends a packet to A, it is possible that the packet is
+forwarded to the CPU. With offload_fwd_mark = 1, the bridge core won't
+forward it back to the switch, resulting in packet loss.
+
+As we have the assisted_learning_on_cpu_port in DSA core now, enable
+that and disable hardware learning on the CPU port.

+Subject: [PATCH] net: dsa: mt7530: use independent VLAN learning on
+ VLAN-unaware bridges
+
+Consider the following bridge configuration, where bond0 is not
+offloaded:
+
+ +-- br0 --+
+ / / | \
+ / / | \
+ / | | bond0
+ / | | / \
+ swp0 swp1 swp2 swp3 swp4
+ . . .
+ . . .
+ A B C
+
+Ideally, when the switch receives a packet from swp3 or swp4, it should
+forward the packet to the CPU, according to the port matrix and unknown
+unicast flood settings.
+
+But packet loss will happen if the destination address is at one of the
+offloaded ports (swp0~2). For example, when client C sends a packet to
+A, the FDB lookup will indicate that it should be forwarded to swp0, but
+the port matrix of swp3 and swp4 is configured to only allow the CPU to
+be its destination, so it is dropped.
+
+However, this issue does not happen if the bridge is VLAN-aware. That is
+because VLAN-aware bridges use independent VLAN learning, i.e. use VID
+for FDB lookup, on offloaded ports. As swp3 and swp4 are not offloaded,
+shared VLAN learning with default filter ID of 0 is used instead. So the
+lookup for A with filter ID 0 never hits and the packet can be forwarded
+to the CPU.
+
+In the current code, only two combinations were used to toggle user
+ports' VLAN awareness: one is PCR.PORT_VLAN set to port matrix mode with
+PVC.VLAN_ATTR set to transparent port, the other is PCR.PORT_VLAN set to
+security mode with PVC.VLAN_ATTR set to user port.
+
+It turns out that only PVC.VLAN_ATTR contributes to VLAN awareness, and
+port matrix mode just skips the VLAN table lookup. The reference manual
+is somehow misleading when describing PORT_VLAN modes. It states that
+PORT_MEM (VLAN port member) is used for destination if the VLAN table
+lookup hits, but actually **PORT_MEM & PORT_MATRIX** (bitwise AND of
+VLAN port member and port matrix) is used instead, which means we can
+have two or more separate VLAN-aware bridges with the same PVID and
+traffic won't leak between them.
+
+Therefore, to solve this, enable independent VLAN learning with PVID 0
+on VLAN-unaware bridges, by setting their PCR.PORT_VLAN to fallback
+mode, while leaving standalone ports in port matrix mode. The CPU port
+is always set to fallback mode to serve those bridges.
+
+During testing, it is found that FDB lookup with filter ID of 0 will
+also hit entries with VID 0 even with independent VLAN learning. To
+avoid that, install all VLANs with filter ID of 1.

+Subject: [PATCH] net: dsa: mt7530: always install FDB entries with IVL and FID
+ 1
+
+This reverts commit 7e777021780e ("mt7530 mt7530_fdb_write only set ivl
+bit vid larger than 1").
+
+Before this series, the default value of all ports' PVID is 1, which is
+copied into the FDB entry, even if the ports are VLAN unaware. So
+`bridge fdb show` will show entries like `dev swp0 vlan 1 self` even on
+a VLAN-unaware bridge.
+
+The blamed commit does not solve that issue completely, instead it may
+cause a new issue that FDB is inaccessible in a VLAN-aware bridge with
+PVID 1.
+
+This series sets PVID to 0 on VLAN-unaware ports, so `bridge fdb show`
+will no longer print `vlan 1` on VLAN-unaware bridges, and that special
+case in fdb_write is not required anymore.
+
+Set FDB entries' filter ID to 1 to match the VLAN table.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+commit 381a730182f1d174e1950cd4e63e885b1c302051 upstream.
+
+Most of dsa_switch_bridge_leave was, in fact, dealing with the syncing
+of VLAN filtering for switches on which that is a global
+setting. Separate the two phases to prepare for the cross-chip related
+bugfix in the following commit.

+Subject: [PATCH 5.10 2/2] net: dsa: Avoid cross-chip syncing of VLAN filtering
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+commit 108dc8741c203e9d6ce4e973367f1bac20c7192b upstream.
+
+Changes to VLAN filtering are not applicable to cross-chip
+notifications.
+
+On a system like this:
+
+.-----. .-----. .-----.
+| sw1 +---+ sw2 +---+ sw3 |
+'-1-2-' '-1-2-' '-1-2-'
+
+Before this change, upon sw1p1 leaving a bridge, a call to
+dsa_port_vlan_filtering would also be made to sw2p1 and sw3p1.
+
+In this scenario:
+
+.---------. .-----. .-----.
+| sw1 +---+ sw2 +---+ sw3 |
+'-1-2-3-4-' '-1-2-' '-1-2-'
+
+When sw1p4 would leave a bridge, dsa_port_vlan_filtering would be
+called for sw2 and sw3 with a non-existing port - leading to array
+out-of-bounds accesses and crashes on mv88e6xxx.
+

+
+commit c1aedf015ebdd0232757a66e2daccf1246bd609c upstream.
+
+Support ECM mode based on cdc_ether with relative mii functions,
+when CONFIG_USB_RTL8152 is not set, or the device is not supported
+by r8152 driver.
+
+Both r8152 and r8153_ecm would check the return value of
+rtl8152_get_version() in porbe(). If rtl8152_get_version()
+return none zero value, the r8152 is used for the device
+with vendor mode. Otherwise, the r8153_ecm is used for the
+device with ECM mode.

+Subject: [PATCH] r8152: replace several functions about phy patch
+ request
+
+commit a08c0d309d8c078d22717d815cf9853f6f2c07bd upstream.
+
+Replace r8153_patch_request() with rtl_phy_patch_request().
+Replace r8153_pre_ram_code() with rtl_pre_ram_code().
+Replace r8153_post_ram_code() with rtl_post_ram_code().
+Add rtl_patch_key_set().
+
+The new functions have an additional parameter. It is used to wait
+the patch request command finished. When the PHY is resumed from
+the state of power cut, the PHY is at a safe mode and the
+OCP_PHY_PATCH_STAT wouldn't be updated. For this situation, it is
+safe to set patch request command without waiting OCP_PHY_PATCH_STAT.

+
+commit 80fd850b31f09263ad175b2f640d5c5c6f76ed41 upstream.
+
+For runtime resuming, the RTL8153B may be resumed from the state
+of power cut, when enabling the feature of UPS. Then, the PHY
+would be reset, so it is necessary to be initailized again.
+
+Besides, the USB_U1U2_TIMER also has to be set again, so I move
+it from r8153b_init() to r8153b_hw_phy_cfg().

+Subject: [PATCH] r8152: set inter fram gap time depending on speed
+
+commit 5133bcc7481528e36fff0a3b056601efb704fb32 upstream.
+
+Set the maximum inter frame gap time (144ns) for speed 10M/half and
+100M/half. It improves the performance for those speeds. And, there
+is no effect for the other speeds.
+
+For 10M/half and 100M/half, the fast inter frame gap time let the
+device couldn't use the feature of the aggregation effectively,
+because the transfer would be completed fastly. Therefore, use the
+maximum value to improve the effect of the aggregation. However, you
+may not feel the improvement for fast CPUs, because they compensate
+for the effect of the aggregation.

+
+The different chips may have different requests when changing mtu.
+Therefore, add a new help function of rtl_ops to change mtu. Besides,
+reset the tx/rx after changing mtu.
+
+Additionally, add mtu_to_size() and size_to_mtu() macros to simplify
+the code.

+
+commit c2198943e33b100ed21dfb636c8fa6baef841e9d upstream.
+
+The vendor mode is not always at config #1, so it is necessary to
+set the correct configuration number.

+
+The generic PCI host driver relies on MSI domains for MSIs to
+be provided to its end-points. Make this dependency explicit.
+
+This cures the warnings occuring on arm/arm64 VMs when booted
+with PCI virtio devices and no MSI controller (no GICv3 ITS,
+for example).
+
+It is likely that other drivers will need to express the same

+
+There is a whole class of host bridges that cannot know whether
+MSIs will be provided or not, as they rely on other blocks
+to provide the MSI functionnality, using MSI domains. This is
+the case for example on systems that use the ARM GIC architecture.

+Introduce a new attribute ('msi_domain') indicating that implicit

+
+Some Mediatek host bridges cannot handle MSIs, which is sad.
+This also results in an ugly warning at device probe time,
+as the core PCI code wasn't told that MSIs were not available.
+
+Advertise this fact to the rest of the core PCI code by
+using the 'msi_domain' attribute, which still opens the possibility
+for another block to provide the MSI functionnality.
+
+[maz: commit message, switched over to msi_domain attribute]

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8

+
+Comphy phy mode 0x3 is incorrectly named. It is not SGMII but rather
+2500Base-X mode which runs at 3.125 Gbps speed.
+
+Rename macro names and comments to 2500Base-X.

+Subject: MIPS: ath79: drop _machine_restart again
+
+Commit 81424d0ad0d4 ("MIPS: ath79: Use the reset controller to restart
+OF machines") removed setup of _machine_restart on OF machines to use
+reset handler in reset controller driver.
+While removing remnants of non-OF machines in commit 3a77e0d75eed
+("MIPS: ath79: drop machfiles"), this was introduced again, making it
+impossible to use additional restart handlers registered through device
+tree. Drop setting _machine_restart altogether, and ath79_restart
+function, which is no longer used after this.

+Subject: hwmon: (lm70) Add ti,tmp125 support
+
+The TMP125 is a 2 degree Celsius accurate Digital
+Temperature Sensor with a SPI interface.
+
+The temperature register is a 16-bit, read-only register.
+The MSB (Bit 15) is a leading zero and never set. Bits 14
+to 5 are the 1+9 temperature data bits in a two's
+complement format. Bits 4 to 0 are useless copies of
+Bit 5 value and therefore ignored.

+
+Upstream GCC uses a libgcc function for saving/restoring registers. This
+makes the code bigger, and upstream kernels need to carry that function
+for every single kernel module. Our GCC is patched to avoid those
+references, so we can drop the extra bloat for modules.

+Subject: [PATCH] drivers: mtd: parsers: add nvmem support to cmdlinepart
+
+Assuming cmdlinepart is only one level deep partition scheme and that
+static partition are also defined in DTS, we can assign an of_node for
+partition declared from bootargs. cmdlinepart have priority than
+fiexed-partition parser so in this specific case the parser doesn't
+assign an of_node. Fix this by searching a defined of_node using a
+similar fixed_partition parser and if a partition is found with the same
+label, check that it has the same offset and size and return the DT
+of_node to correctly use NVMEM cells.

+Subject: [PATCH] netfilter: connmark: introduce set-dscpmark
+
+set-dscpmark is a method of storing the DSCP of an ip packet into
+conntrack mark. In combination with a suitable tc filter action
+(act_ctinfo) DSCP values are able to be stored in the mark on egress and
+restored on ingress across links that otherwise alter or bleach DSCP.
+
+This is useful for qdiscs such as CAKE which are able to shape according
+to policies based on DSCP.
+
+Ingress classification is traditionally a challenging task since
+iptables rules haven't yet run and tc filter/eBPF programs are pre-NAT
+lookups, hence are unable to see internal IPv4 addresses as used on the
+typical home masquerading gateway.
+
+x_tables CONNMARK set-dscpmark target solves the problem of storing the
+DSCP to the conntrack mark in a way suitable for the new act_ctinfo tc
+action to restore.
+
+The set-dscpmark option accepts 2 parameters, a 32bit 'dscpmask' and a
+32bit 'statemask'. The dscp mask must be 6 contiguous bits and
+represents the area where the DSCP will be stored in the connmark. The
+state mask is a minimum 1 bit length mask that must not overlap with the
+dscpmask. It represents a flag which is set when the DSCP has been
+stored in the conntrack mark. This is useful to implement a 'one shot'
+iptables based classification where the 'complicated' iptables rules are
+only run once to classify the connection on initial (egress) packet and
+subsequent packets are all marked/restored with the same DSCP. A state
+mask of zero disables the setting of a status bit/s.
+
+example syntax with a suitably modified iptables user space application:
+
+iptables -A QOS_MARK_eth0 -t mangle -j CONNMARK --set-dscpmark 0xfc000000/0x01000000
+
+Would store the DSCP in the top 6 bits of the 32bit mark field, and use
+the LSB of the top byte as the 'DSCP has been stored' marker.
+
+|----0xFC----conntrack mark----000000---|
+| Bits 31-26 | bit 25 | bit24 |~~~ Bit 0|
+| DSCP | unused | flag |unused |
+|-----------------------0x01---000000---|
+ ^ ^
+ | |
+ ---| Conditional flag
+ | set this when dscp
+|-ip diffserv-| stored in mark
+| 6 bits |
+|-------------|
+
+an identically configured tc action to restore looks like:
+
+tc filter show dev eth0 ingress
+filter parent ffff: protocol all pref 10 u32 chain 0
+filter parent ffff: protocol all pref 10 u32 chain 0 fh 800: ht divisor 1
+filter parent ffff: protocol all pref 10 u32 chain 0 fh 800::800 order 2048 key ht 800 bkt 0 flowid 1: not_in_hw
+ match 00000000/00000000 at 0
+ action order 1: ctinfo zone 0 pipe
+ index 2 ref 1 bind 1 dscp 0xfc000000/0x1000000
+
+ action order 2: mirred (Egress Redirect to device ifb4eth0) stolen
+ index 1 ref 1 bind 1

+
+This fix for ARM does not account ARCH_PFN_OFFSET for mem_map as later used by
+page_to_pfn anymore.
+
+The following output was generated with two hacked in printk statements:
+
+printk("before %p vs. %p or %p\n", mem_map, mem_map - offset, mem_map -
+(pgdat->node_start_pfn - ARCH_PFN_OFFSET));
+ if (page_to_pfn(mem_map) != pgdat->node_start_pfn)
+ mem_map -= offset + (pgdat->node_start_pfn - ARCH_PFN_OFFSET);
+printk("after %p\n", mem_map);
+
+Output:
+
+[ 0.000000] before 8861b280 vs. 8861b280 or 8851b280
+[ 0.000000] after 8851b280
+
+As seen in the first line mem_map with subtraction of offset does not equal the
+mem_map after subtraction of ARCH_PFN_OFFSET.
+
+After adding the offset of ARCH_PFN_OFFSET as well to mem_map as the
+previously calculated offset is zero for the named platform it is able to boot
+4.4 and 4.9-rc7 again.

+
+Many MIPS CPUs have optional CPU features which are not activates for
+all CPU cores. Print the CPU options which are implemented in the core
+in /proc/cpuinfo. This makes it possible to see what features are
+supported and which are not supported. This should cover all standard
+MIPS extensions, before it only printed information about the main MIPS
+ASEs.

+Do not prevent writing to mtd partitions where a partition boundary sits
+on a minor erasesize boundary.
+This addresses a FIXME that has been present since the start of the
+linux git history:
+/* Doesn't start on a boundary of major erase size */
+/* FIXME: Let it be writable if it is on a boundary of
+ * _minor_ erase size though */
+
+Allow a uniform erase region spi-nor device to be configured
+to use the non-uniform erase regions code path for an erase with:
+CONFIG_MTD_SPI_NOR_USE_VARIABLE_ERASE=y
+
+On supporting hardware (SECT_4K: majority of current SPI-NOR device)
+provide the facility for an erase to use the least number
+of SPI-NOR operations, as well as access to 4K erase without
+requiring CONFIG_MTD_SPI_NOR_USE_4K_SECTORS
+
+Introduce erasesize_minor to the mtd struct,
+the smallest erasesize supported by the device
+
+On existing devices, this is useful where write support is wanted
+for data on a 4K partition, such as some u-boot-env partitions,
+or RouterBoot soft_config, while still netting the performance
+benefits of using 64K sectors
+
+Performance:
+time mtd erase firmware

+Subject: [PATCH] mtd: parsers: ofpart: fix parsing subpartitions
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+ofpart was recently patched to not scan random partition nodes as
+subpartitions. That change unfortunately broke scanning valid
+subpartitions like:
+
+partitions {
+ compatible = "fixed-partitions";
+ #address-cells = <1>;
+ #size-cells = <1>;
+
+ partition@0 {
+ compatible = "fixed-partitions";
+ label = "bootloader";
+ reg = <0x0 0x100000>;
+
+ partition@0 {
+ label = "config";
+ reg = <0x80000 0x80000>;
+ };
+ };
+};
+
+Fix that regression by adding 1 more code path. We actually need 3
+conditional blocks to support 3 possible cases. This change also makes
+code easier to understand & follow.

+Subject: [PATCH] mtd: spi-nor: support limiting 4K sectors support based on
+ flash size
+
+Some devices need 4K sectors to be able to deal with small flash chips.
+For instance, w25x05 is 64 KiB in size, and without 4K sectors, the
+entire chip is just one erase block.
+On bigger flash chip sizes, using 4K sectors can significantly slow down
+many operations, including using a writable filesystem. There are several
+platforms where it makes sense to use a single kernel on both kinds of
+devices.
+
+To support this properly, allow configuring an upper flash chip size
+limit for 4K sectors support.

+Subject: [PATCH 497/497] mtd: mtdconcat: add dt driver for concat devices
+
+Some mtd drivers like physmap variants have support for concatenating
+multiple mtd devices, but there is no generic way to define such a
+concat device from within the device tree.
+
+This is useful for some SoC boards that use multiple flash chips as
+memory banks of a single mtd device, with partitions spanning chip
+borders.
+
+This commit adds a driver for creating virtual mtd-concat devices. They
+must have a compatible = "mtd-concat" line, and define a list of devices
+to concat in the 'devices' property, for example:
+
+flash {
+ compatible = "mtd-concat";
+
+ devices = <&flash0 &flash1>;
+
+ partitions {
+ ...
+ };
+};
+
+The driver is added to the very end of the mtd Makefile to increase the
+likelyhood of all child devices already being loaded at the time of
+probing, preventing unnecessary deferred probes.

+
+Macronix MX25L6405D supports locking with four block-protection bits.
+Currently, the driver only sets three bits. If the bootloader does not
+sustain the flash chip in an unlocked state, the flash might be
+non-writeable. Add the corresponding flag to enable locking support with
+four bits in the status register.
+
+Tested on Nanostation M2 XM.

+Subject: [PATCH] net_sched/codel: do not defer queue length update
+
+When codel wants to drop last packet in ->dequeue() it cannot call
+qdisc_tree_reduce_backlog() right away - it will notify parent qdisc
+about zero qlen and HTB/HFSC will deactivate class. The same class will
+be deactivated second time by caller of ->dequeue(). Currently codel and
+fq_codel defer update. This triggers warning in HFSC when it's qlen != 0
+but there is no active classes.
+
+This patch update parent queue length immediately: just temporary increase
+qlen around qdisc_tree_reduce_backlog() to prevent first class deactivation
+if we have skb to return.
+
+This might open another problem in HFSC - now operation peek could fail and
+deactivate parent class.

+
+MAP-E FMRs (draft-ietf-softwire-map-10) are rules for IPv4-communication
+between MAP CEs (mesh mode) without the need to forward such data to a
+border relay. This is similar to how 6rd works but for IPv4 over IPv6.

+Subject: [PATCH] of_net: add mac-address-increment support
+
+Lots of embedded devices use the mac-address of other interface
+extracted from nvmem cells and increments it by one or two. Add two
+bindings to integrate this and directly use the right mac-address for
+the interface. Some example are some routers that use the gmac
+mac-address stored in the art partition and increments it by one for the
+wifi. mac-address-increment-byte bindings is used to tell what byte of
+the mac-address has to be increased (if not defined the last byte is
+increased) and mac-address-increment tells how much the byte decided
+early has to be increased.

+Subject: [PATCH] bridge: add knob for filtering rx/tx BPDU packets on a port
+
+Some devices (e.g. wireless APs) can't have devices behind them be part of
+a bridge topology with redundant links, due to address limitations.
+Additionally, broadcast traffic on these devices is somewhat expensive, due to
+the low data rate and wakeups of clients in powersave mode.
+This knob can be used to ensure that BPDU packets are never sent or forwarded
+to/from these devices

+Subject: [PATCH] net: bridge: switchdev: Include local flag in FDB
+ notifications
+
+Some switchdev drivers, notably DSA, ignore all dynamically learned
+address notifications (!added_by_user) as these are autonomously added
+by the switch. Previously, such a notification was indistinguishable
+from a local address notification. Include a local bit in the
+notification so that the two classes can be discriminated.
+
+This allows DSA-like devices to add local addresses to the hardware
+FDB (with the CPU as the destination), thereby avoiding flows towards
+the CPU being flooded by the switch as unknown unicast.

+Subject: [PATCH] bcma: get SoC device struct & copy its DMA params to the
+ subdevices
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+For bus devices to be fully usable it's required to set their DMA
+parameters.
+
+For years it has been missing and remained unnoticed because of
+mips_dma_alloc_coherent() silently handling the empty coherent_dma_mask.
+Kernel 4.19 came with a lot of DMA changes and caused a regression on
+the bcm47xx. Starting with the commit f8c55dc6e828 ("MIPS: use generic
+dma noncoherent ops for simple noncoherent platforms") DMA coherent
+allocations just fail. Example:
+[ 1.114914] bgmac_bcma bcma0:2: Allocation of TX ring 0x200 failed
+[ 1.121215] bgmac_bcma bcma0:2: Unable to alloc memory for DMA
+[ 1.127626] bgmac_bcma: probe of bcma0:2 failed with error -12
+[ 1.133838] bgmac_bcma: Broadcom 47xx GBit MAC driver loaded
+
+This change fixes above regression in addition to the MIPS bcm47xx
+commit 321c46b91550 ("MIPS: BCM47XX: Setup struct device for the SoC").
+
+It also fixes another *old* GPIO regression caused by a parent pointing
+to the NULL:
+[ 0.157054] missing gpiochip .dev parent pointer
+[ 0.157287] bcma: bus0: Error registering GPIO driver: -22
+introduced by the commit 74f4e0cc6108 ("bcma: switch GPIO portions to
+use GPIOLIB_IRQCHIP").

+Subject: [PATCH 2/2] gpio: gpio-cascade: add generic GPIO cascade
+
+Adds support for building cascades of GPIO lines. That is, it allows
+setups when there is one upstream line and multiple cascaded lines, out
+of which one can be chosen at a time. The status of the upstream line
+can be conveyed to the selected cascaded line or, vice versa, the status
+of the cascaded line can be conveyed to the upstream line.
+
+A multiplexer is being used to select, which cascaded GPIO line is being
+used at any given time.
+
+At the moment only input direction is supported. In future it should be
+possible to add support for output direction, too.

+---
+v7 -> v8:
+ - rearrange members in struct gpio_cascade
+ - cosmetic changes in file header and in one function declaration
+ - added Reviewed-by tags by Linus and Andy
+v6 -> v7:
+ - In Kconfig add info about module name
+ - adhere to new convention that allows lines longer than 80 chars
+ - use dev_probe_err with upstream gpio line too
+ - refactor for cleaner exit of probe function.
+v5 -> v6:
+ - In Kconfig, remove dependency to OF_GPIO and select only MULTIPLEXER
+ - refactor code preferring one-liners
+ - clean up prints, removing them from success-path.
+ - don't explicitly set gpio_chip.of_node as it's done in the GPIO library
+ - use devm_gpiochip_add_data instead of gpiochip_add
+v4 -> v5:
+ - renamed gpio-mux-input -> gpio-cascade. refactored code accordingly
+ here and there and changed to use new bindings and compatible string
+ - ambigious and vague 'pin' was rename to 'upstream_line'
+ - dropped Tested-by and Reviewed-by due to changes in bindings
+ - dropped Reported-by suggested by an automatic bot as it was not really
+ appropriate to begin with
+ - functionally it's the same as v4
+v3 -> v4:
+ - Changed author email
+ - Included Tested-by and Reviewed-by from Drew
+v2 -> v3:
+ - use managed device resources
+ - update Kconfig description
+v1 -> v2:
+ - removed .owner from platform_driver as per test bot's instruction
+ - added MODULE_AUTHOR, MODULE_DESCRIPTION, MODULE_LICENSE
+ - added gpio_mux_input_get_direction as it's recommended for all chips
+ - removed because this is input only chip: gpio_mux_input_set_value
+ - removed because they are not needed for input/output only chips:
+ gpio_mux_input_direction_input
+ gpio_mux_input_direction_output
+ - fixed typo in an error message
+ - added info message about successful registration
+ - removed can_sleep flag as this does not sleep while getting GPIO value
+ like I2C or SPI do
+ - Updated description in Kconfig

+Subject: [PATCH] PCI: aardvark: Fix reading MSI interrupt number
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+In advk_pcie_handle_msi() the authors expect that when bit i in the W1C
+register PCIE_MSI_STATUS_REG is cleared, the PCIE_MSI_PAYLOAD_REG is
+updated to contain the MSI number corresponding to index i.
+
+Experiments show that this is not so, and instead PCIE_MSI_PAYLOAD_REG
+always contains the number of the last received MSI, overall.
+
+Do not read PCIE_MSI_PAYLOAD_REG register for determining MSI interrupt
+number. Since Aardvark already forbids more than 32 interrupts and uses
+own allocated hwirq numbers, the msi_idx already corresponds to the
+received MSI number.

+Subject: [PATCH] PCI: aardvark: Fix support for MSI interrupts
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Aardvark hardware supports Multi-MSI and MSI_FLAG_MULTI_PCI_MSI is already
+set for the MSI chip. But when allocating MSI interrupt numbers for
+Multi-MSI, the numbers need to be properly aligned, otherwise endpoint
+devices send MSI interrupt with incorrect numbers.
+
+Fix this issue by using function bitmap_find_free_region() instead of
+bitmap_find_next_zero_area().
+
+To ensure that aligned MSI interrupt numbers are used by endpoint devices,
+we cannot use Linux virtual irq numbers (as they are random and not
+properly aligned). Instead we need to use the aligned hwirq numbers.
+
+This change fixes receiving MSI interrupts on Armada 3720 boards and
+allows using NVMe disks which use Multi-MSI feature with 3 interrupts.
+
+Without this NVMe disks freeze booting as linux nvme-core.c is waiting
+60s for an interrupt.

+Rewrite the code to use irq_set_chained_handler_and_data() handler with

+devm_request_irq().
+
+advk_pcie_irq_handler() reads IRQ status bits and calls other functions

+bits and calls other aardvark functions based on these bits. Finally
+generic_handle_domain_irq() with translated linux IRQ numbers are called.

+
+Marc Zyngier says [1] that we should use struct irq_chip as a global
+static struct in the driver. Even though the structure currently
+contains a dynamic member (parent_device), Marc says [2] that he plans
+to kill it and make the structure completely static.
+
+Convert Aardvark's priv->msi_bottom_irq_chip and priv->msi_irq_chip to
+static driver structure.

+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+MSI address for receiving MSI interrupts needs to be correctly set before
+enabling processing of MSI interrupts.
+
+Move code for setting PCIE_MSI_ADDR_LOW_REG and PCIE_MSI_ADDR_HIGH_REG
+from advk_pcie_init_msi_irq_domain() to advk_pcie_setup_hw(), before
+enabling PCIE_CORE_CTRL2_MSI_ENABLE.
+
+After this we can remove the now unused member msi_msg, which was used
+only for MSI doorbell address. MSI address can be any address which cannot
+be used to DMA to. So change it to the address of the main struct advk_pcie.

+Subject: [PATCH] PCI: aardvark: Enable MSI-X support
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+According to PCI 3.0 specification, sending both MSI and MSI-X interrupts
+is done by DWORD memory write operation to doorbell message address. The
+write operation for MSI has zero upper 16 bits and the MSI interrupt number
+in the lower 16 bits, while the write operation for MSI-X contains a 32-bit
+value from MSI-X table.
+
+Since the driver only uses interrupt numbers from range 0..31, the upper
+16 bits of the DWORD memory write operation to doorbell message address
+are zero even for MSI-X interrupts. Thus we can enable MSI-X interrupts.
+
+Testing proves that kernel can correctly receive MSI-X interrupts from PCIe
+cards which supports both MSI and MSI-X interrupts.

+Subject: [PATCH] PCI: aardvark: Add support for ERR interrupt on emulated
+ bridge
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+ERR interrupt is triggered when corresponding bit is unmasked in both ISR0
+and PCI_EXP_DEVCTL registers. Unmasking ERR bits in PCI_EXP_DEVCTL register
+is not enough. This means that currently the ERR interrupt is never
+triggered.
+
+Unmask ERR bits in ISR0 register at driver probe time. ERR interrupt is not
+triggered until ERR bits are unmasked also in PCI_EXP_DEVCTL register,
+which is done by AER driver. So it is safe to unconditionally unmask all
+ERR bits in aardvark probe.

+Aardvark HW sets PCI_ERR_ROOT_AER_IRQ to zero and when corresponding bits

+on GIC. Chain this interrupt to PCIe interrupt 0 with
+generic_handle_domain_irq() to allow processing of ERR interrupts.

+
+The emulated bridge returns incorrect value for PCI_EXP_RTSTA register
+during readout in advk_pci_bridge_emul_pcie_conf_read() function: the
+correct bit is BIT(16), but we are setting BIT(23), because the code
+does
+ *value = (isr0 & PCIE_MSG_PM_PME_MASK) << 16
+where
+ PCIE_MSG_PM_PME_MASK
+is
+ BIT(7).
+
+The code should probably have been something like
+ *value = (!!(isr0 & PCIE_MSG_PM_PME_MASK)) << 16,
+but we are better of using an if() and using the proper macro for this
+bit.

+Subject: [PATCH] PCI: aardvark: Add support for PME interrupts
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Currently enabling PCI_EXP_RTSTA_PME bit in PCI_EXP_RTCTL register does
+nothing. This is because PCIe PME driver expects to receive PCIe interrupt
+defined in PCI_EXP_FLAGS_IRQ register, but aardvark hardware does not
+trigger PCIe INTx/MSI interrupt for PME event, rather it triggers custom
+aardvark interrupt which this driver is not processing yet.
+
+Fix this issue by handling PME interrupt in advk_pcie_handle_int() and
+chaining it to PCIe interrupt 0 with generic_handle_domain_irq() (since
+aardvark sets PCI_EXP_FLAGS_IRQ to zero). With this change PCIe PME driver
+finally starts receiving PME interrupt.

+Subject: [PATCH] PCI: aardvark: Fix support for PME requester on emulated
+ bridge
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Enable aardvark PME interrupt unconditionally by unmasking it and read PME
+requester ID to emulated bridge config space immediately after receiving
+interrupt.
+
+PME requester ID is stored in the PCIE_MSG_LOG_REG register, which contains
+the last inbound message. So when new inbound message is received by HW
+(including non-PM), the content in PCIE_MSG_LOG_REG register is replaced by
+a new value.
+
+PCIe specification mandates that subsequent PMEs are kept pending until the
+PME Status Register bit is cleared by software by writing a 1b.
+
+Support for masking/unmasking PME interrupt on emulated bridge via
+PCI_EXP_RTCTL_PMEIE bit is now implemented only in emulated bridge config
+space, to ensure that we do not miss any aardvark PME interrupt.
+
+Reading of PCI_EXP_RTCAP and PCI_EXP_RTSTA registers is simplified as final
+value is now always stored into emulated bridge config space by the
+interrupt handler, so there is no need to implement support for these
+registers in read_pcie callback.
+
+Clearing of W1C bit PCI_EXP_RTSTA_PME is now also simplified as it is done
+by pci-bridge-emul.c code for emulated bridge config space. So there is no
+need to implement support for clearing this bit in write_pcie callback.

+Subject: [PATCH] PCI: aardvark: Use separate INTA interrupt for emulated root
+ bridge
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Emulated root bridge currently provides only one Legacy INTA interrupt
+which is used for reporting PCIe PME and ERR events and handled by kernel
+PCIe PME and AER drivers.
+
+Aardvark HW reports these PME and ERR events separately, so there is no
+need to mix real INTA interrupt and emulated INTA interrupt for PCIe PME
+and AER drivers.
+
+Register a new advk-RP (as in Root Port) irq chip and a new irq domain
+for emulated root bridge and use this new separate irq domain for
+providing INTA interrupt from emulated root bridge for PME and ERR events.
+
+The real INTA interrupt from real devices is now separate.
+
+A custom map_irq callback function on PCI host bridge structure is used to
+allocate IRQ mapping for emulated root bridge from new irq domain. Original
+callback of_irq_parse_and_map_pci() is used for all other devices as before.

+Subject: [PATCH] PCI: aardvark: Make main irq_chip structure a static driver
+ structure
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Marc Zyngier says [1] that we should use struct irq_chip as a global
+static struct in the driver. Even though the structure currently
+contains a dynamic member (parent_device), Marc says [2] that he plans
+to kill it and make the structure completely static.
+
+We have already converted others irq_chip structures in this driver in
+this way, but we omitted this one because the .name member is
+dynamically created from device's name, and the name is displayed in
+sysfs, so changing it would break sysfs ABI.
+
+The rationale for changing the name (to "advk-INT") in spite of sysfs
+ABI, and thus allowing to convert to a static structure, is that after
+the other changes we made in this series, the IRQ chip is basically
+something different: it no logner generates ERR and PME interrupts (they
+are generated by emulated bridge's rp_irq_chip).

+Subject: [PATCH] phy: marvell: phy-mvebu-a3700-comphy: Remove port from driver
+ configuration
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Port number is encoded into argument for SMC call. It is zero for SATA,
+PCIe and also both USB 3.0 PHYs. It is non-zero only for Ethernet PHY
+(incorrectly called SGMII) on lane 0. Ethernet PHY on lane 1 also uses zero
+port number.
+
+So construct "port" bits for SMC call argument can be constructed directly
+from PHY type and lane number.
+
+Change driver code to always pass zero port number for non-ethernet PHYs
+and for ethernet PHYs determinate port number from lane number. This
+simplifies the driver.
+
+As port number from DT PHY configuration is not used anymore, remove whole
+driver code which parses it. This also simplifies the driver.

+Subject: [PATCH] phy: marvell: phy-mvebu-a3700-comphy: Add native kernel
+ implementation
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Remove old RPC implementation and add a new native kernel implementation.
+
+The old implementation uses ARM SMC API to issue RPC calls to ARM Trusted
+Firmware which provides real implementation of PHY configuration.
+
+But older versions of ARM Trusted Firmware do not provide this PHY
+configuration functionality, simply returning: operation not supported; or
+worse, some versions provide the configuration functionality incorrectly.
+
+For example the firmware shipped in ESPRESSObin board has this older
+version of ARM Trusted Firmware and therefore SATA, USB 3.0 and PCIe
+functionality do not work with newer versions of Linux kernel.
+
+Due to the above reasons, the following commits were introduced into Linux,
+to workaround these issues by ignoring -EOPNOTSUPP error code from
+phy-mvebu-a3700-comphy driver function phy_power_on():
+
+commit 45aefe3d2251 ("ata: ahci: mvebu: Make SATA PHY optional for Armada
+3720")
+commit 3241929b67d2 ("usb: host: xhci: mvebu: make USB 3.0 PHY optional for
+Armada 3720")
+commit b0c6ae0f8948 ("PCI: aardvark: Fix initialization with old Marvell's
+Arm Trusted Firmware")
+
+Replace this RPC implementation with proper native kernel implementation,
+which is independent on the firmware. Never return -EOPNOTSUPP for proper
+arguments.
+
+This should solve multiple issues with real-world boards, where it is not
+possible or really inconvenient to change the firmware. Let's eliminate
+these issues.
+
+This implementation is ported directly from Armada 3720 comphy driver found
+in newest version of ARM Trusted Firmware source code, but with various
+fixes of register names, some added comments, some refactoring due to the
+original code not conforming to kernel standards. Also PCIe mode poweroff
+support was added here, and PHY reset support. These changes are also going
+to be sent to ARM Trusted Firmware.

+[ Pali did the porting from ATF.
+ I (Marek) then fixed some register names, some various other things,
+ added some comments and refactored the code to kernel standards. Also
+ fixed PHY poweroff and added PHY reset. ]

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Kernel driver phy-mvebu-a3700-comphy.c needs to know the rate of the
+reference xtal clock. So add missing xtal clock source into comphy device
+tree node. If the property is not present, the driver defaults to 25 MHz
+xtal rate (which, as far as we know, is used by all the existing boards).

+Armada 3720 PHY driver (phy-mvebu-a3700-comphy.c) does not return

+So remove AHCI_HFLAG_IGN_NOTSUPP_POWER_ON flag from Armada 3720 plat data.
+
+AHCI_HFLAG_IGN_NOTSUPP_POWER_ON is not used by any other ahci driver, so
+remove this flag completely.
