+Subject: [PATCH 01/15] mtd: nand: ecc: Add infrastructure to support hardware
+ engines
+
+Add the necessary helpers to register/unregister hardware ECC engines
+that will be called from ECC engine drivers.
+
+Also add helpers to get the right engine from the user
+perspective. Keep a reference of the in use ECC engine in order to
+prevent modules to be unloaded. Put the reference when the engine gets
+retired.
+
+A static list of hardware (only) ECC engines is setup to keep track of
+the registered engines.

+Subject: [PATCH 03/15] mtd: nand: ecc: Provide a helper to retrieve a
+ pilelined engine device
+
+In a pipelined engine situation, we might either have the host which
+internally has support for error correction, or have it using an
+external hardware block for this purpose. In the former case, the host
+is also the ECC engine. In the latter case, it is not. In order to get
+the right pointers on the right devices (for example: in order to devm_*
+allocate variables), let's introduce this helper which can safely be
+called by pipelined ECC engines in order to retrieve the right device
+structure.

+Create a spi_controller_mem_caps structure and put it within the

+
+Controllers can now provide a spi-mem capabilities structure. Let's make
+use of it in spi_mem_controller_default_supports_op(). As we want to
+check for DTR operations as well as normal operations in a single

+for now.
+
+However, because no controller provide these extra capabilities, this

+
+Now that spi_mem_default_supports_op() has access to the static
+controller capabilities (relating to memory operations), and now that
+these capabilities have been filled by the relevant controllers, there
+is no need for a specific helper checking only DTR operations, so let's

+spi_mem_default_supports_op() instead.

+Soon the SPI-NAND core will need a way to request a SPI controller to

+
+Introduce a spi_mem_op additional field for this purpose: ecc.

+Subject: [PATCH 09/15] mtd: spinand: Create direct mapping descriptors for ECC
+ operations
+
+In order for pipelined ECC engines to be able to enable/disable the ECC
+engine only when needed and avoid races when future parallel-operations
+will be supported, we need to provide the information about the use of
+the ECC engine in the direct mapping hooks. As direct mapping
+configurations are meant to be static, it is best to create two new
+mappings: one for regular 'raw' accesses and one for accesses involving
+correction. It is up to the driver to use or not the new ECC enable
+boolean contained in the spi-mem operation.
+
+As dirmaps are not free (they consume a few pages of MMIO address space)
+and because these extra entries are only meant to be used by pipelined
+engines, let's limit their use to this specific type of engine and save
+a bit of memory with all the other setups.

+Subject: [PATCH v6 2/5] spi: add driver for MTK SPI NAND Flash Interface
+
+This driver implements support for the SPI-NAND mode of MTK NAND Flash
+Interface as a SPI-MEM controller with pipelined ECC capability.
+
+Signed-off-by: Chuanhong Guo <gch981213@gmail.com>
+Tested-by: Daniel Golle <daniel@makrotopia.org>
+---
+Change since v1:
+ fix CI warnings
+
+Changes since v2:
+ use streamed DMA api to avoid an extra memory copy during read
+ make ECC engine config a per-nand context
+ take user-requested ECC strength into account
+
+Change since v3: none
+Changes since v4:
+ fix missing OOB write
+ print page format with dev_dbg
+ replace uint*_t copied from vendor driver with u*
+
+Changes since v5:
+ add missing nfi mode register configuration in probe
+ fix an off-by-one bug in mtk_snand_mac_io

++// This controller organize the page data as several interleaved sectors
++// like the following: (sizeof(FDM + ECC) = snf->nfi_cfg.spare_size)
++// +---------+------+------+---------+------+------+-----+
++// | Sector1 | FDM1 | ECC1 | Sector2 | FDM2 | ECC2 | ... |
++// +---------+------+------+---------+------+------+-----+
++// With auto-format turned on, DMA only returns this part:
++// +---------+---------+-----+
++// | Sector1 | Sector2 | ... |
++// +---------+---------+-----+
++// The FDM data will be filled to the registers, and ECC parity data isn't
++// accessible.
++// With auto-format off, all ((Sector+FDM+ECC)*nsectors) will be read over DMA
++// in it's original order shown in the first table. ECC can't be turned on when
++// auto-format is off.
++//
++// However, Linux SPI-NAND driver expects the data returned as:
++// +------+-----+
++// | Page | OOB |
++// +------+-----+
++// where the page data is continuously stored instead of interleaved.
++// So we assume all instructions matching the page_op template between ECC
++// prepare_io_req and finish_io_req are for page cache r/w.
++// Here's how this spi-mem driver operates when reading:
++// 1. Always set snf->autofmt = true in prepare_io_req (even when ECC is off).
++// 2. Perform page ops and let the controller fill the DMA bounce buffer with
++// de-interleaved sector data and set FDM registers.
++// 3. Return the data as:
++// +---------+---------+-----+------+------+-----+
++// | Sector1 | Sector2 | ... | FDM1 | FDM2 | ... |
++// +---------+---------+-----+------+------+-----+
++// 4. For other matching spi_mem ops outside a prepare/finish_io_req pair,
++// read the data with auto-format off into the bounce buffer and copy
++// needed data to the buffer specified in the request.
++//
++// Write requests operates in a similar manner.
++// As a limitation of this strategy, we won't be able to access any ECC parity
++// data at all in Linux.
++//
++// Here's the bad block mark situation on MTK chips:
++// In older chips like mt7622, MTK uses the first FDM byte in the first sector
++// as the bad block mark. After de-interleaving, this byte appears at [pagesize]
++// in the returned data, which is the BBM position expected by kernel. However,
++// the conventional bad block mark is the first byte of the OOB, which is part
++// of the last sector data in the interleaved layout. Instead of fixing their
++// hardware, MTK decided to address this inconsistency in software. On these
++// later chips, the BootROM expects the following:
++// 1. The [pagesize] byte on a nand page is used as BBM, which will appear at
++// (page_size - (nsectors - 1) * spare_size) in the DMA buffer.
++// 2. The original byte stored at that position in the DMA buffer will be stored
++// as the first byte of the FDM section in the last sector.
++// We can't disagree with the BootROM, so after de-interleaving, we need to
++// perform the following swaps in read:
++// 1. Store the BBM at [page_size - (nsectors - 1) * spare_size] to [page_size],
++// which is the expected BBM position by kernel.
++// 2. Store the page data byte at [pagesize + (nsectors-1) * fdm] back to
++// [page_size - (nsectors - 1) * spare_size]
++// Similarly, when writing, we need to perform swaps in the other direction.

+
+With the current range specified for the CPU interface there is an
+error message at boot:
+
+GIC: GICv2 detected, but range too small and irqchip.gicv2_force_probe not set
+
+Setting irqchip.gicv2_force_probe=1 in bootargs results in:
+
+GIC: Aliased GICv2 at 0x0000000010320000, trying to find the canonical range over 128kB
+GIC: Adjusting CPU interface base to 0x000000001032f000
+GIC: Using split EOI/Deactivate mode
+
+Using the adjusted CPU interface base and 8K size results in only the
+final line remaining and fully working system as well as /proc/interrupts
+showing additional IPI3,4,5,6:
+
+IPI3: 0 0 CPU stop (for crash dump) interrupts
+IPI4: 0 0 Timer broadcast interrupts
+IPI5: 0 0 IRQ work interrupts
+IPI6: 0 0 CPU wake-up interrupts

+On an MT7622 system, the kernel complains of not being able to detect the cache
+hierarchy of CPU 0. Specify the shared L2 cache node in the device tree, in

+The MT7622 device tree never bothered to specify the number of virtual DMA
+channels for the HSDMA controller, always falling back to the default value of
+3. Make this value explicit, in order to avoid the following dmesg notification:

+Subject: [PATCH] mediatek: mt7623: fix thermal zone
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Raising the temperatures for passive and active trips. @VA1DER
+proposed at issue 9396 to remove passive trip. This commit relates to
+his suggestion.
+
+Without this patch. the CPU will be throttled all the way down to 98MHz
+if the temperature rises even a degree above the trip point, and it was
+further discovered that if the internal temperature of the device is
+above the first trip point temperature when it boots then it will start
+in a throttled state and even
+$ echo disabled > /sys/class/thermal/thermal_zone0/mode
+will have no effect.
+
+The patch increases the passive trip point and active cooling map. The
+throttling temperature will then be at 77°C and 82°C, which is still a
+low enough temperature for ARM devices to not be in the real danger
+zone, and gives some operational headroom.

+Subject: [PATCH 10/21] cpufreq: mediatek: Refine
+ mtk_cpufreq_voltage_tracking()
+
+Because the difference of sram and proc should in a range of min_volt_shift
+and max_volt_shift. We need to adjust the sram and proc step by step.
+
+We replace VOLT_TOL (voltage tolerance) with the platform data and update the
+logic to determine the voltage boundary and invoking regulator_set_voltage.
+
+- Use 'sram_min_volt' and 'sram_max_volt' to determine the voltage boundary
+ of sram regulator.
+- Use (sram_min_volt - min_volt_shift) and 'proc_max_volt' to determine the
+ voltage boundary of vproc regulator.
+
+Moreover, to prevent infinite loop when tracking voltage, we calculate the
+maximum value for each platform data.
+We assume min voltage is 0 and tracking target voltage using
+min_volt_shift for each iteration.
+The retry_max is 3 times of expeted iteration count.

+Subject: [PATCH 13/21] cpufreq: mediatek: Link CCI device to CPU
+
+In some MediaTek SoCs, like MT8183, CPU and CCI share the same power
+supplies. Cpufreq needs to check if CCI devfreq exists and wait until
+CCI devfreq ready before scaling frequency.
+
+Before CCI devfreq is ready, we record the voltage when booting to
+kernel and use the max(cpu target voltage, booting voltage) to
+prevent cpufreq adjust to the lower voltage which will cause the CCI
+crash because of high frequency and low voltage.
+
+- Add is_ccifreq_ready() to link CCI device to CPI, and CPU will start
+ DVFS when CCI is ready.
+- Add platform data for MT8183.

+ MT8516
+
+Since the upper boundary of proc/sram voltage of MT8516 is 1300 mV,
+which is greater than the value of MT2701 1150 mV, we fix it by adding
+the corresponding platform data and specify proc/sram_max_volt to
+support MT8516.

+Subject: [PATCH 20/21] cpufreq: mediatek: Raise proc and sram max voltage for
+ MT7622/7623
+
+During the addition of SRAM voltage tracking for CCI scaling, this
+driver got some voltage limits set for the vtrack algorithm: these
+were moved to platform data first, then enforced in a later commit
+6a17b3876bc8 ("cpufreq: mediatek: Refine mtk_cpufreq_voltage_tracking()")
+using these as max values for the regulator_set_voltage() calls.
+
+In this case, the vsram/vproc constraints for MT7622 and MT7623
+were supposed to be the same as MT2701 (and a number of other SoCs),
+but that turned out to be a mistake because the aforementioned two
+SoCs' maximum voltage for both VPROC and VPROC_SRAM is 1.36V.
+
+Fix that by adding new platform data for MT7622/7623 declaring the
+right {proc,sram}_max_volt parameter.
+
+Fixes: ead858bd128d ("cpufreq: mediatek: Move voltage limits to platform data")

+Subject: [PATCH] cpufreq: mediatek: correct voltages for MT7622 and MT7623
+
+The MT6380 regulator typically used together with MT7622 does not
+support the current maximum processor and SRAM voltage in the cpufreq
+driver (1360000uV).
+For MT7622 limit processor and SRAM supply voltages to 1350000uV to
+avoid having the tracking algorithm request unsupported voltages from
+the regulator.
+
+On MT7623 there is no separate SRAM supply and the maximum voltage used
+is 1300000uV. Create dedicated platform data for MT7623 to cover that
+case as well.
+
+Fixes: 0883426fd07e3 ("cpufreq: mediatek: Raise proc and sram max voltage for MT7622/7623")

+Subject: [PATCH] arm64: dts: mediatek: Split PCIe node for MT2712 and MT7622
+
+There are two independent PCIe controllers in MT2712 and MT7622
+platform. Each of them should contain an independent MSI domain.
+
+In old dts architecture, MSI domain will be inherited from the root
+bridge, and all of the devices will share the same MSI domain.
+Hence that, the PCIe devices will not work properly if the irq number
+which required is more than 32.
+
+Split the PCIe node for MT2712 and MT7622 platform to comply with
+the hardware design and fix MSI issue.

+
+The lowest frequency should be 300MHz, since that is the label
+assigned to the OPP in the mt7622.dtsi device tree, while there is one
+missing zero in the actual value.
+
+To be clear, the lowest frequency should be 300MHz instead of 30MHz.
+
+As mentioned @dangowrt on the OpenWrt forum there is no benefit in

+Subject: [PATCH] net: phy: add driver for MediaTek SoC built-in GE PHYs
+
+Some of MediaTek's Filogic SoCs come with built-in gigabit Ethernet
+PHYs which require calibration data from the SoC's efuse.
+Despite the similar design the driver doesn't share any code with the
+existing mediatek-ge.c, so add support for these PHYs by introducing a
+new driver for only MediaTek's ARM64 SoCs.

+Subject: [PATCH] pinctrl: mediatek: Fix EINT pins input debounce time
+ configuration
+
+The External Interrupt Controller (EINTC) on all of the supported
+MediaTek SoCs does support input debouncing, but not all of them
+index the debounce time values (DBNC_SETTING registers) the same way.
+
+Before this change, in some cases, as an example, requesting a debounce
+time of 16 milliseconds would mistakenly set the relative DBNC_SETTING
+register to 0x2, resulting in a way shorter debounce time of 500uS.
+
+To fix the aforementioned issue, define three different debounce_time
+arrays, reflecting the correct register index for each value and for
+each register index variant, and make sure that each SoC pinctrl
+driver uses the right one.

++ The RT5190A integrates 1 channel buck controller, 3 channels high efficiency
++ synchronous buck converters, 1 LDO, I2C control interface and peripherial
++ logical control.
++
++ It also supports mute AC OFF depop sound and quick setting storage while
++ input power is removed.

++ The mute function uses 'mutein', 'muteout', and 'vdet' pins as the control
++ signal. When enabled, The normal behavior is to bypass the 'mutein' signal
++ 'muteout'. But if the power source removal is detected from 'vdet',
++ whatever the 'mutein' signal is, it will pull down the 'muteout' to force
++ speakers mute. this function is commonly used to prevent the speaker pop
++ noise during AC power turned off in the modern TV system design.

+Subject: [PATCH 02/16] i2c: mediatek: Dump i2c/dma register when a timeout
+ occurs
+
+When a timeout error occurs in i2c transter, it is usually related
+to the i2c/dma IP hardware configuration. Therefore, the purpose of
+this patch is to dump the key register values of i2c/dma when a
+timeout occurs in i2c for debugging.

+Subject: [PATCH 06/16] i2c: mt65xx: Simplify with clk-bulk
+
+Since depending on the SoC or specific bus functionality some clocks
+may be optional, we cannot get the benefit of using devm_clk_bulk_get()
+but, by migrating to clk-bulk, we are able to remove the custom functions
+mtk_i2c_clock_enable() and mtk_i2c_clock_disable(), increasing common
+APIs usage, hence (lightly) decreasing kernel footprint.

+Subject: [PATCH 08/16] i2c: mediatek: Optimize master_xfer() and avoid
+ circular locking
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Especially (but not only) during probe, it may happen that multiple
+devices are communicating via i2c (or multiple i2c busses) and
+sometimes while others are probing asynchronously.
+For example, a Cr50 TPM may be filling entropy (or userspace may be
+reading random data) while the rt5682 (i2c) codec driver reads/sets
+some registers, like while getting/setting a clock's rate, which
+happens both during probe and during system operation.
+
+In this driver, the mtk_i2c_transfer() function (which is the i2c
+.master_xfer() callback) was granularly managing the clocks by
+performing a clk_bulk_prepare_enable() to start them and its inverse.
+This is not only creating possible circular locking dependencies in
+the some cases (like former explanation), but it's also suboptimal,
+as clk_core prepare/unprepare operations are using mutex locking,
+which creates a bit of unwanted overhead (for example, i2c trackpads
+will call master_xfer() every few milliseconds!).
+
+With this commit, we avoid both the circular locking and additional
+overhead by changing how we handle the clocks in this driver:
+- Prepare the clocks during probe (and PM resume)
+- Enable/disable clocks in mtk_i2c_transfer()
+- Unprepare the clocks only for driver removal (and PM suspend)
+
+For the sake of providing a full explanation: during probe, the
+clocks are not only prepared but also enabled, as this is needed
+for some hardware initialization but, after that, we are disabling
+but not unpreparing them, leaving an expected state for the
+aforementioned clock handling strategy.

+Subject: [PATCH 11/16] i2c: move drivers from strlcpy to strscpy
+
+Follow the advice of the below link and prefer 'strscpy'. Conversion is
+easy because no driver used the return value and has been done with a
+simple sed invocation.

+
+In some cases, we may need watchdog just to trigger an
+internal soc reset without sending any output signal.
+
+Provide a disable_wdt_extrst parameter for configuration.
+We can disable or enable it just by configuring dts.

+Subject: [PATCH net-next 3/3] net: ethernet: mtk_wed: move dlm a dedicated dts
+ node
+
+Since the dlm memory region is not part of the RAM SoC, move dlm in a
+deidicated syscon node.
+This patch helps to keep backward-compatibility with older version of
+uboot codebase where we have a limit of 8 reserved-memory dts child
+nodes.
+Keep backward-compatibility with older dts version where dlm was defined
+as reserved-memory child node.
