+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 02/69] dmaengine: Add ADM driver
+
+Original patch by Andy Gross.
+
+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.

+Subject: [PATCH 31/69] mtd: add SMEM parser for QCOM platforms
+
+On QCOM platforms using MTD devices storage (such as IPQ806x), SMEM is
+used to store partition layout. This new parser can now be used to read
+SMEM and use it to register an MTD layout according to its content.

+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
+according to the device-tree content. This allows multiple PCIe
+controllers to coexist in the system.

+
+Krait CPUs have a handful of L2 cache controller registers that
+live behind a cp15 based indirection register. First you program
+the indirection register (l2cpselr) to point the L2 'window'
+register (l2cpdr) at what you want to read/write. Then you
+read/write the 'window' register to do what you want. The
+l2cpselr register is not banked per-cpu so we must lock around
+accesses to it to prevent other CPUs from re-pointing l2cpdr
+underneath us.

+We want to reuse the logic in clk-mux.c for other clock drivers
+that don't use readl as register accessors. Fortunately, there
+really isn't much to the mux code besides the table indirection
+and quirk flags if you assume any bit shifting and masking has
+been done already. Pull that logic out into reusable functions
+that operate on an optional table and some flags so that other
+drivers can use the same logic.

+
+On some devices (MSM8974 for example), the HFPLLs are
+instantiated within the Krait processor subsystem as separate
+register regions. Add a driver for these PLLs so that we can
+provide HFPLL clocks for use by the system.

+
+The Krait clocks are made up of a series of muxes and a divider
+that choose between a fixed rate clock and dedicated HFPLLs for
+each CPU. Instead of using mmio accesses to remux parents, the
+Krait implementation exposes the remux control via cp15
+registers. Support these clocks.

+
+The Krait CPU clocks are made up of a primary mux and secondary
+mux for each CPU and the L2, controlled via cp15 accessors. For
+Kraits within KPSSv1 each secondary mux accepts a different aux
+source, but on KPSSv2 each secondary mux accepts the same aux
+source.

+
+When the Hfplls are reprogrammed during the rate change,
+the primary muxes which are sourced from the same hfpll
+for higher frequencies, needs to be switched to the 'safe
+secondary mux' as the parent for that small window. This
+is done by registering a clk notifier for the muxes and
+switching to the safe parent in the PRE_RATE_CHANGE notifier
+and back to the original parent in the POST_RATE_CHANGE notifier.

+The Platform data was removed earlier by,
+'commit eb96924acddc ("cpufreq: dt: Kill platform-data")'
+since there were no users at that time.
+Now this is required when the each of the cpu clocks
+can be scaled independently, which is the case
+for krait cores. So reintroduce it.

+Subject: [PATCH 47/69] mtd: nand: Create a BBT flag to access bad block
+ markers in raw mode
+
+Some controllers can access the factory bad block marker from OOB only
+when they read it in raw mode. When ECC is enabled, these controllers
+discard reading/writing bad block markers, preventing access to them
+altogether.
+
+The bbt driver assumes MTD_OPS_PLACE_OOB when scanning for bad blocks.
+This results in the nand driver's ecc->read_oob() op to be called, which
+works with ECC enabled.
+
+Create a new BBT option flag that tells nand_bbt to force the mode to
+MTD_OPS_RAW. This would result in the correct op being called for the
+underlying nand controller driver.

+Subject: [PATCH 49/69] PM / OPP: Support adjusting OPP voltages at runtime
+
+On some SoCs the Adaptive Voltage Scaling (AVS) technique is
+employed to optimize the operating voltage of a device. At a
+given frequency, the hardware monitors dynamic factors and either
+makes a suggestion for how much to adjust a voltage for the
+current frequency, or it automatically adjusts the voltage
+without software intervention. Add an API to the OPP library for
+the former case, so that AVS type devices can update the voltages
+for an OPP when the hardware determines the voltage should
+change. The assumption is that drivers like CPUfreq or devfreq
+will register for the OPP notifiers and adjust the voltage
+according to suggestions that AVS makes.

+
+When the voltage is adjusted, the voltage tolerance is not updated.
+This can lead to situations where the voltage min value is greater

+in the regulator core.
+Fix this by updating the voltage tolerance values too.

+Subject: [PATCH 54/69] cpufreq-dt: Handle OPP voltage adjust events
+
+On some SoCs the Adaptive Voltage Scaling (AVS) technique is
+employed to optimize the operating voltage of a device. At a
+given frequency, the hardware monitors dynamic factors and either
+makes a suggestion for how much to adjust a voltage for the
+current frequency, or it automatically adjusts the voltage
+without software intervention.
+
+In the former case, an AVS driver will call
+dev_pm_opp_modify_voltage() and update the voltage for the
+particular OPP the CPUs are using. Add an OPP notifier to
+cpufreq-dt so that we can adjust the voltage of the CPU when AVS
+updates the OPP.

+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.

+
+ipq8064: tsens: TSENS driver support for IPQ8064
+
+Support for IPQ8064 tsens driver. The driver works
+with the thermal framework. The driver overrides the
+following fucntionalities:
+
+1. Get current temperature.
+2. Get/Set trip temperatures.
+3. Enabled/Disable trip points.
+4. ISR for threshold generated interrupt.
+5. Notify userspace when trip points are hit.

+Subject: [PATCH] ipq8064: tsens: Support for configurable interrupts
+
+Provide support for adding configurable high and
+configurable low trip temperatures. An interrupts is
+also triggerred when these trip points are hit. The
+interrupts can be activated or deactivated from sysfs.
+This functionality is made available only if
+CONFIG_THERMAL_WRITABLE_TRIPS is defined.

+The command-line arguments provided by the boot loader will be

+If there is a property "append-rootblock" in DT under /chosen
+and a root= option in bootloaders command line it will be parsed

+ (dw_pcie_host_init) from [] (qcom_pcie_probe+0x20c/0x2e4)
+
+pcie_phy_clk is generated for PCIe controller itself and the
+GCC controls its branch operation. This error is coming since
+the assert operations turn off the parent clock before branch
+clock. Now this patch moves clk_disable_unprepare before assert
+operations.
+
+Similarly, during probe function, the clock branch operation
+should be done after dessert operation. Currently, it does not
+generate any error since bootloader enables the pcie_phy_clk
+but the same error is coming during probe, if bootloader
+disables pcie_phy_clk.

+Subject: pinctrl: qcom: use scm_call to route GPIO irq to Apps
+
+For IPQ806x targets, TZ protects the registers that are used to
+configure the routing of interrupts to a target processor.
+To resolve this, this patch uses scm call to route GPIO interrupts
+to application processor. Also the scm call interface is changed.

+Subject: [PATCH] mtd: nand: add Winbond manufacturer and chip
+
+This patch adds the W25N01GV NAND to the table of
+known devices. Without this patch the device gets detected:
+
+nand: device found, Manufacturer ID: 0xef, Chip ID: 0xaa
+nand: Unknown NAND 256MiB 1,8V 8-bit
+nand: 256 MiB, SLC, erase size: 64 KiB, page size: 1024, OOB size : 16
+
+Whereas the u-boot identifies it as:
+spi_nand: spi_nand_flash_probe SF NAND ID 00:ef:aa:21
+SF: Detected W25N01GV with page size 2 KiB, total 128 MiB
+
+Due to the page size discrepancy, it's impossible to attach
+ubi volumes on the device.

+Subject: mtd: spi-nor: add mx25l25635f with SECT_4K
+
+This patch fixes an issue with the creation of the
+ubi volume on the AVM FRITZ!Box 4040. The mx25l25635f
+and mx25l25635e support SECT_4K which will set the
+erase size to 4K. This is used by ubi to calculate
+VID header offsets. Without this, uboot and linux
+disagrees about the layout and refuse to attach
+the ubi volume created by the other.
