+Subject: [PATCH 01/69] dtbindings: qcom_adm: Fix channel specifiers
+
+Original patch from Andy Gross.
+
+This patch removes the crci information from the dma
+channel property. At least one client device requires
+using more than one CRCI value for a channel. This does
+not match the current binding and the crci information
+needs to be removed.
+
+Instead, the client device will provide this information
+via other means.

+Subject: [PATCH 33/69] ARM: qcom: automatically select PCI_DOMAINS if PCI is
+ enabled
+
+If multiple PCIe devices are present in the system, the kernel will
+panic at boot time when trying to scan the PCI buses. This happens on
+IPQ806x based platforms, which has 3 PCIe ports.
+
+Enabling this option allows the kernel to assign the pci-domains

+Subject: [PATCH 60/69] HACK: arch: arm: force ZRELADDR on arch-qcom
+
+ARCH_QCOM is using the ARCH_MULTIPLATFORM option, as now recommended
+on most ARM architectures. This automatically calculate ZRELADDR by
+masking PHYS_OFFSET with 0xf8000000.
+
+However, on IPQ806x, the first ~20MB of RAM is reserved for the hardware
+network accelerators, and the bootloader removes this section from the
+layout passed from the ATAGS (when used).
+
+For newer bootloader, when DT is used, this is not a problem, we just
+reserve this memory in the device tree. But if the bootloader doesn't
+have DT support, then ATAGS have to be used. In this case, the ARM
+decompressor will position the kernel in this low mem, which will not be
+in the RAM section mapped by the bootloader, which means the kernel will
+freeze in the middle of the boot process trying to map the memory.
+
+As a work around, this patch allows disabling AUTO_ZRELADDR when
+ARCH_QCOM is selected. It makes the zImage usage possible on bootloaders
+which don't support device-tree, which is the case on certain early
+IPQ806x based designs.

+Subject: [PATCH 1/4] ipq806x: gcc: add missing clk flag
+
+Some flag are missing from the original code.
+These clk can't be set using the protected-clock proprities as they
+cause the malfunction of the serial interface.
+These clks are needed for the rpm interface to work proprely or the
+cpu regulators starts to fail as soon as they are disabled by the
+kernel.

+Subject: [PATCH 1/8] cpufreq: add Krait dedicated scaling driver
+
+This new driver is based on generic cpufreq-dt driver.
+Krait SoCs have 2-4 cpu and one shared L2 cache that can
+operate at different frequency based on the maximum cpu clk
+across all core.
+L2 frequency and voltage are scaled on every frequency change
+if needed. On Krait SoCs is present a bug that can cause
+transition problem between frequency bin, to workaround this
+on more than one transition, the L2 frequency is first set to the
+base rate and then to the target rate.
+The L2 frequency use the OPP framework and use the opp-level
+bindings to link the l2 freq to different cpu freq. This is needed
+as the Krait l2 clk are note mapped 1:1 to the core clks and some
+of the l2 clk is set based on a range of the cpu clks. If the driver
+find a broken config (for example no opp-level set) the l2 scaling is
+skipped.

++title: CPU Frequency scaling driver for Krait SoCs
++
++maintainers:
++ - Ansuel Smith <ansuelsmth@gmail.com>
++
++description: |
++ The krait cpufreq driver is a dedicated frequency scaling driver
++ based on cpufreq-dt generic driver that scale L2 cache and the
++ cores. TEST
++
++ The L2 cache is scaled based on the max clk across all cores and
++ the clock is decided based on the opp-level set in the device tree.
++
++ Different core freq can be linked to a specific l2 freq and the driver
++ on frequency change will scale the core and the l2 clk based of the
++ linked freq.
++
++ On Krait SoC is present a bug and on every L2 clk change the driver
++ needs to set the clk to the idle freq before changing it to the new value.
++
++ This requires the qcom cpufreq nvmem driver to parse the different opp
++ core clk and an additional opp table for the l2 scaling.
++
++ If the driver detect broken config (for example missing opp-level) the
++ cpufreq driver skips the l2 scaling
++
++ Referring to this example opp-level can be used to link a range of cpu freq
++ to a specific l2 freq:
++ cpu opp freq 384000000 has opp-level 0
++ l2 opp freq 384000000 has opp-level 0
++ The driver will scale l2 to 384000000
++
++ cpu opp freq 600000000-1000000000 has opp-level 1
++ l2 opp freq 1000000000 has opp-level 1
++ The driver will scale l2 to 1000000000

+
+ipq806x nand have a special ecc configuration for the boot pages. The
+use of the non-boot pages configuration on boot pages cause I/O error
+and can cause broken data written to the nand. Add support for this
+special configuration if the page to be read/write is in the size of the
+boot pages set by the dts.

+Subject: dmaengine: qcom: Add ADM driver
+
+Add the DMA engine driver for the QCOM Application Data Mover (ADM) DMA
+controller found in the MSM8x60 and IPQ/APQ8064 platforms.
+
+The ADM supports both memory to memory transactions and memory
+to/from peripheral device transactions. The controller also provides
+flow control capabilities for transactions to/from peripheral devices.
+
+The initial release of this driver supports slave transfers to/from
+peripherals and also incorporates CRCI (client rate control interface)
+flow control.
+
+The hardware only supports a 32 bit physical address, so specifying
+!PHYS_ADDR_T_64BIT gives maximum COMPILE_TEST coverage without having to
+spend effort on kludging things in the code that will never actually be
+needed on real hardware.

+Subject: [PATCH] ARM: dts: qcom: reduce pci IO size to 64K
+
+The current value is probably a typo and is actually uncommon to find
+1MB IO space even on a x86 arch. Also with recent changes to the pci
+driver, pci1 and pci2 now fails to function as any connected device
+fails any reg read/write. Reduce this to 64K as it should be more than
+enough and 3 * 64K of total IO space doesn't exceed the IO_SPACE_LIMIT
+hardcoded for the ARM arch.

+Subject: [PATCH 01/10] drivers: thermal: tsens: Add VER_0 tsens version
+
+VER_0 is used to describe device based on tsens version before v0.1.
+These device are devices based on msm8960 for example apq8064 or
+ipq806x.

+Function compute_intercept_slope hardcode the sensor slope to
+SLOPE_DEFAULT. Change this and use the default value only if a slope is

+Subject: net: stmmac: explicitly deassert GMAC_AHB_RESET
+
+We are currently assuming that GMAC_AHB_RESET will already be deasserted
+by the bootloader. However if this has not been done, probing of the GMAC
+will fail. To remedy this we must ensure GMAC_AHB_RESET has been deasserted
+prior to probing.
+
+v2 changes:
+ - remove NULL condition check for stmmac_ahb_rst in stmmac_main.c
+ - unwrap dev_err() message in stmmac_main.c
+ - add PTR_ERR() around plat->stmmac_ahb_rst in stmmac_platform.c
+
+v3 changes:
+ - add error pointer to dev_err() output
+ - add reset_control_assert(stmmac_ahb_rst) in stmmac_dvr_remove
+ - revert PTR_ERR() around plat->stmmac_ahb_rst since this is performed
+ on the returned value of ret by the calling function
