-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.

-
-This patch fixes a few issues with the DMA mode. The QUP needs to be
-placed in the run mode before the DMA transactions are executed. The
-conditions for being able to DMA vary between revisions of the QUP.
-This is due to v1.1.1 using ADM DMA and later revisions using BAM.

-Subject: [PATCH 07/69] spi: qup: properly detect extra interrupts
-
-It's possible for a SPI transaction to complete and get another
-interrupt and have it processed on the same spi_transfer before the
-transfer_one can set it to NULL.
-
-This masks unexpected interrupts, so let's set the spi_transfer to
-NULL in the interrupt once the transaction is done. So we can
-properly detect these bad interrupts and print warning messages.

-From: Matthew McClintock <mmcclint@codeaurora.org>
-Date: Tue, 26 Apr 2016 15:46:24 -0500
-Subject: [PATCH 11/69] spi: qup: allow block mode to generate multiple
- transactions
-
-This let's you write more to the SPI bus than 64K-1 which is important
-if the block size of a SPI device is >= 64K or some other device wants
-to something larger.
-
-This has the benefit of completly removing spi_message from the spi-qup
-transactions

-Subject: [PATCH 14/69] spi: qup: Fix sg nents calculation
-
-lib/scatterlist.c:sg_nents_for_len() returns the number of SG
-entries that total up to greater than or equal to the given
-length. However, the spi-qup driver assumed that the returned
-nents is for a total less than or equal to the given length. The
-spi-qup driver requests nents for SPI_MAX_XFER, however the API
-returns nents for SPI_MAX_XFER+delta (actually SZ_64K).
-
-Based on this, spi_qup_do_dma() calculates n_words and programs
-that into QUP_MX_{IN|OUT}PUT_CNT register. The calculated
-n_words value is more than the maximum value that can fit in the
-the 16-bit COUNT field of the QUP_MX_{IN|OUT}PUT_CNT register.
-And, the field gets programmed to zero. Since the COUNT field is
-zero, the i/o doesn't start eventually resulting in the i/o
-timing out.

-
-This adds initial support for clocks controlled by the Resource

-Such platforms are msm8916, apq8084 and msm8974.

-The RPM is a dedicated hardware engine for managing the shared
-SoC resources in order to keep the lowest power profile. It

-and accepts clock requests, aggregates the requests and turns
-the clocks on/off or scales them on demand.
-
-This driver is based on the codeaurora.org driver:

-Subject: [PATCH 28/69] clk: qcom: Add support for RPM Clocks
-
-This adds initial support for clocks controlled by the Resource
-Power Manager (RPM) processor on some Qualcomm SoCs, which use
-the qcom_rpm driver to communicate with RPM.
-Such platforms are apq8064 and msm8960.

-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.

-On some devices (MSM8974 for example), the HFPLLs are

-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.

-Subject: [PATCH 50/69] OPP: Allow notifiers to call dev_pm_opp_get_{voltage,
- freq} RCU-free
-
-We pass the dev_pm_opp structure to OPP notifiers but the users
-of the notifier need to surround calls to dev_pm_opp_get_*() with
-RCU read locks to avoid lockdep warnings. The notifier is already
-called with the dev_opp's srcu lock held, so it should be safe to
-assume the devm_pm_opp structure is already protected inside the
-notifier. Update the lockdep check for this.

-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.

-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
-appended to a new device tree property: bootloader-args.
-If there is a property "append-rootblock" in DT under /chosen
-and a root= option in bootloaders command line it will be parsed
-and added to DT bootargs with the form: <append-rootblock>XX.
-Only command line ATAG will be processed, the rest of the ATAGs
-sent by bootloader will be ignored.
-This is usefull in dual boot systems, to get the current root partition
-without afecting the rest of the system.

- (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.

-
-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.
