-From: Kumar Gala <galak@codeaurora.org>
-Date: Thu, 23 Jan 2014 14:09:54 -0600
-Subject: [PATCH 001/182] ARM: dts: msm: split out msm8660 and msm8960 soc
- into dts include
-
-Pull the SoC device tree bits into their own files so other boards based
-on these SoCs can include them and reduce duplication across a number of
-boards.

-pen_release is no longer required as the synchronization
-is now managed by generic arm code.
-This is done as suggested in https://lkml.org/lkml/2013/6/4/184

-Subject: [PATCH 005/182] ARM: qcom: Split Qualcomm support into legacy and
- multiplatform
-
-Introduce a new mach-qcom that will support SoCs that intend to be
-multiplatform compatible while keeping mach-msm to legacy SoC/board
-support that will not transition over to multiplatform.
-
-As part of this, we move support for MSM8X60, MSM8960 and MSM8974 over
-to mach-qcom.

-Subject: [PATCH 008/182] ARM: Introduce CPU_METHOD_OF_DECLARE() for cpu
- hotplug/smp
-
-The goal of multi-platform kernels is to remove the need for mach
-directories and machine descriptors. To further that goal,
-introduce CPU_METHOD_OF_DECLARE() to allow cpu hotplug/smp
-support to be separated from the machine descriptors.
-Implementers should specify an enable-method property in their
-cpus node and then implement a matching set of smp_ops in their
-hotplug/smp code, wiring it up with the CPU_METHOD_OF_DECLARE()
-macro. When the kernel is compiled we'll collect all the
-enable-method smp_ops into one section for use at boot.
-
-At boot time we'll look for an enable-method in each cpu node and
-try to match that against all known CPU enable methods in the
-kernel. If there are no enable-methods in the cpu nodes we
-fallback to the cpus node and try to use any enable-method found
-there. If that doesn't work we fall back to the old way of using
-the machine descriptor.

-
-Currently, the wake_irqs bitmap is used to track whether there are any
-gpio's which are configured as wake irqs, and uses this to determine
-whether or not to call enable_irq_wake()/disable_irq_wake() on the
-summary interrupt.
-
-However, the genirq core already handles this case, by maintaining a
-'wake_count' per irq_desc, and only calling into the controlling
-irq_chip when wake_count transitions 0 <-> 1.
-
-Drop this bitmap, and unconditionally call irq_set_irq_wake() on the
-summary interrupt.

-
-=============================================
-[ INFO: possible recursive locking detected ]
-3.14.0-rc3 #2 Not tainted
----------------------------------------------
-modprobe/52 is trying to acquire lock:
- (&irq_desc_lock_class){-.....}, at: [<c026aea0>] __irq_get_desc_lock+0x48/0x88

-but task is already holding lock:
- (&irq_desc_lock_class){-.....}, at: [<c026aea0>] __irq_get_desc_lock+0x48/0x88
-
-other info that might help us debug this:
- Possible unsafe locking scenario:
-
- CPU0
- ----
- lock(&irq_desc_lock_class);
- lock(&irq_desc_lock_class);
-
- *** DEADLOCK ***
-
- May be due to missing lock nesting notation
-

-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-This driver is only useful on MSM8x74, so let the driver depend on
-ARCH_QCOM but allow compile coverage testing.
-The main benefit is that the driver isn't available to be selected for
-machines that don't have the matching hardware.

-+Qualcomm IPQ8064 TLMM block
-+
-+Required properties:
-+- compatible: "qcom,ipq8064-pinctrl"
-+- reg: Should be the base address and length of the TLMM block.
-+- interrupts: Should be the parent IRQ of the TLMM block.
-+- interrupt-controller: Marks the device node as an interrupt controller.
-+- #interrupt-cells: Should be two.
-+- gpio-controller: Marks the device node as a GPIO controller.
-+- #gpio-cells : Should be two.
-+ The first cell is the gpio pin number and the
-+ second cell is used for optional parameters.
-+
-+Please refer to ../gpio/gpio.txt and ../interrupt-controller/interrupts.txt for
-+a general description of GPIO and interrupt bindings.
-+
-+Please refer to pinctrl-bindings.txt in this directory for details of the
-+common pinctrl bindings used by client devices, including the meaning of the
-+phrase "pin configuration node".
-+
-+Qualcomm's pin configuration nodes act as a container for an abitrary number of
-+subnodes. Each of these subnodes represents some desired configuration for a
-+pin, a group, or a list of pins or groups. This configuration can include the
-+mux function to select on those pin(s)/group(s), and various pin configuration
-+parameters, such as pull-up, drive strength, etc.
-+
-+The name of each subnode is not important; all subnodes should be enumerated
-+and processed purely based on their content.
-+
-+Each subnode only affects those parameters that are explicitly listed. In
-+other words, a subnode that lists a mux function but no pin configuration
-+parameters implies no information about any pin configuration parameters.
-+Similarly, a pin subnode that describes a pullup parameter implies no
-+information about e.g. the mux function.
-+
-+
-+The following generic properties as defined in pinctrl-bindings.txt are valid
-+to specify in a pin configuration subnode:
-+
-+ pins, function, bias-disable, bias-pull-down, bias-pull,up, drive-strength,
-+ output-low, output-high.
-+
-+Non-empty subnodes must specify the 'pins' property.
-+
-+Valid values for qcom,pins are:
-+ gpio0-gpio68
-+ Supports mux, bias, and drive-strength
-+
-+ sdc3_clk, sdc3_cmd, sdc3_data
-+ Supports bias and drive-strength
-+
-+
-+Valid values for function are:
-+ mdio, mi2s, pdm, ssbi, spmi, audio_pcm, gsbi1, gsbi2, gsbi4, gsbi5,
-+ gsbi5_spi_cs1, gsbi5_spi_cs2, gsbi5_spi_cs3, gsbi6, gsbi7, nss_spi, sdc1,
-+ spdif, nand, tsif1, tsif2, usb_fs_n, usb_fs, usb2_hsic, rgmii2, sata,
-+ pcie1_rst, pcie1_prsnt, pcie1_pwren_n, pcie1_pwren, pcie1_pwrflt,

-+QCOM BAM DMA controller
-+
-+Required properties:
-+- compatible: must contain "qcom,bam-v1.4.0" for MSM8974
-+- reg: Address range for DMA registers
-+- interrupts: Should contain the one interrupt shared by all channels
-+- #dma-cells: must be <1>, the cell in the dmas property of the client device
-+ represents the channel number
-+- clocks: required clock
-+- clock-names: must contain "bam_clk" entry
-+- qcom,ee : indicates the active Execution Environment identifier (0-7) used in
-+ the secure world.
-+
-+Example:
-+
-+ uart-bam: dma@f9984000 = {
-+ compatible = "qcom,bam-v1.4.0";
-+ reg = <0xf9984000 0x15000>;
-+ interrupts = <0 94 0>;
-+ clocks = <&gcc GCC_BAM_DMA_AHB_CLK>;
-+ clock-names = "bam_clk";
-+ #dma-cells = <1>;
-+ qcom,ee = <0>;
-+ };
-+
-+DMA clients must use the format described in the dma.txt file, using a two cell
-+specifier for each channel.
-+
-+Example:
-+ serial@f991e000 {
-+ compatible = "qcom,msm-uart";
-+ reg = <0xf991e000 0x1000>
-+ <0xf9944000 0x19000>;

-Subject: [PATCH 045/182] dmaengine: add Qualcomm BAM dma driver
-
-Add the DMA engine driver for the QCOM Bus Access Manager (BAM) DMA controller
-found in the MSM 8x74 platforms.
-
-Each BAM DMA device is associated with a specific on-chip peripheral. Each
-channel provides a uni-directional data transfer engine that is capable of
-transferring data between the peripheral and system memory (System mode), or
-between two peripherals (BAM2BAM).
-
-The initial release of this driver only supports slave transfers between
-peripherals and system memory.

-+ * QCOM BAM DMA engine driver
-+ *
-+ * QCOM BAM DMA blocks are distributed amongst a number of the on-chip
-+ * peripherals on the MSM 8x74. The configuration of the channels are dependent
-+ * on the way they are hard wired to that specific peripheral. The peripheral
-+ * device tree entries specify the configuration of each channel.
-+ *
-+ * The DMA controller requires the use of external memory for storage of the
-+ * hardware descriptors for each channel. The descriptor FIFO is accessed as a
-+ * circular buffer and operations are managed according to the offset within the
-+ * FIFO. After pipe/channel reset, all of the pipe registers and internal state
-+ * are back to defaults.
-+ *
-+ * During DMA operations, we write descriptors to the FIFO, being careful to
-+ * handle wrapping and then write the last FIFO offset to that channel's
-+ * P_EVNT_REG register to kick off the transaction. The P_SW_OFSTS register
-+ * indicates the current FIFO offset that is being processed, so there is some
-+ * indication of where the hardware is currently working.

-+* Qualcomm SDHCI controller (sdhci-msm)
-+
-+This file documents differences between the core properties in mmc.txt
-+and the properties used by the sdhci-msm driver.
-+
-+Required properties:
-+- compatible: Should contain "qcom,sdhci-msm-v4".
-+- reg: Base address and length of the register in the following order:
-+ - Host controller register map (required)
-+ - SD Core register map (required)
-+- interrupts: Should contain an interrupt-specifiers for the interrupts:
-+ - Host controller interrupt (required)
-+- pinctrl-names: Should contain only one value - "default".
-+- pinctrl-0: Should specify pin control groups used for this controller.
-+- clocks: A list of phandle + clock-specifier pairs for the clocks listed in clock-names.
-+- clock-names: Should contain the following:
-+ "iface" - Main peripheral bus clock (PCLK/HCLK - AHB Bus clock) (required)
-+ "core" - SDC MMC clock (MCLK) (required)
-+ "bus" - SDCC bus voter clock (optional)
-+
-+Example:
-+
-+ sdhc_1: sdhci@f9824900 {
-+ compatible = "qcom,sdhci-msm-v4";
-+ reg = <0xf9824900 0x11c>, <0xf9824000 0x800>;
-+ interrupts = <0 123 0>;
-+ bus-width = <8>;
-+ non-removable;
-+
-+ vmmc = <&pm8941_l20>;
-+ vqmmc = <&pm8941_s3>;
-+
-+ pinctrl-names = "default";
-+ pinctrl-0 = <&sdc1_clk &sdc1_cmd &sdc1_data>;
-+
-+ clocks = <&gcc GCC_SDCC1_APPS_CLK>, <&gcc GCC_SDCC1_AHB_CLK>;
-+ clock-names = "core", "iface";
-+ };
-+
-+ sdhc_2: sdhci@f98a4900 {
-+ compatible = "qcom,sdhci-msm-v4";
-+ reg = <0xf98a4900 0x11c>, <0xf98a4000 0x800>;
-+ interrupts = <0 125 0>;
-+ bus-width = <4>;
-+ cd-gpios = <&msmgpio 62 0x1>;
-+
-+ vmmc = <&pm8941_l21>;
-+ vqmmc = <&pm8941_l13>;
-+
-+ pinctrl-names = "default";
-+ pinctrl-0 = <&sdc2_clk &sdc2_cmd &sdc2_data>;
-+
-+ clocks = <&gcc GCC_SDCC2_APPS_CLK>, <&gcc GCC_SDCC2_AHB_CLK>;

-Subject: [PATCH 049/182] drivers: of: add initialization code for static
- reserved memory
-
-This patch adds support for static (defined by 'reg' property) reserved
-memory regions declared in device tree.
-
-Memory blocks can be reliably reserved only during early boot. This must
-happen before the whole memory management subsystem is initialized,
-because we need to ensure that the given contiguous blocks are not yet
-allocated by kernel. Also it must happen before kernel mappings for the
-whole low memory are created, to ensure that there will be no mappings
-(for reserved blocks). Typically, all this happens before device tree
-structures are unflattened, so we need to get reserved memory layout
-directly from fdt.

-+*** Reserved memory regions ***
-+
-+Reserved memory is specified as a node under the /reserved-memory node.
-+The operating system shall exclude reserved memory from normal usage
-+one can create child nodes describing particular reserved (excluded from
-+normal use) memory regions. Such memory regions are usually designed for
-+the special usage by various device drivers.
-+
-+Parameters for each memory region can be encoded into the device tree
-+with the following nodes:
-+
-+/reserved-memory node
-+---------------------
-+#address-cells, #size-cells (required) - standard definition
-+ - Should use the same values as the root node
-+ranges (required) - standard definition
-+ - Should be empty
-+
-+/reserved-memory/ child nodes
-+-----------------------------
-+Each child of the reserved-memory node specifies one or more regions of
-+reserved memory. Each child node may either use a 'reg' property to
-+specify a specific range of reserved memory, or a 'size' property with
-+optional constraints to request a dynamically allocated block of memory.
-+
-+Following the generic-names recommended practice, node names should
-+reflect the purpose of the node (ie. "framebuffer" or "dma-pool"). Unit
-+address (@<address>) should be appended to the name if the node is a
-+static allocation.
-+
-+Properties:
-+Requires either a) or b) below.
-+a) static allocation
-+ reg (required) - standard definition
-+b) dynamic allocation
-+ size (required) - length based on parent's #size-cells
-+ - Size in bytes of memory to reserve.
-+ alignment (optional) - length based on parent's #size-cells
-+ - Address boundary for alignment of allocation.
-+ alloc-ranges (optional) - prop-encoded-array (address, length pairs).
-+ - Specifies regions of memory that are
-+ acceptable to allocate from.
-+
-+If both reg and size are present, then the reg property takes precedence
-+and size is ignored.
-+
-+Additional properties:
-+compatible (optional) - standard definition
-+ - may contain the following strings:
-+ - shared-dma-pool: This indicates a region of memory meant to be
-+ used as a shared pool of DMA buffers for a set of devices. It can
-+ be used by an operating system to instanciate the necessary pool
-+ management subsystem if necessary.
-+ - vendor specific string in the form <vendor>,[<device>-]<usage>
-+no-map (optional) - empty property
-+ - Indicates the operating system must not create a virtual mapping
-+ of the region as part of its standard mapping of system memory,
-+ nor permit speculative access to it under any circumstances other
-+ than under the control of the device driver using the region.
-+reusable (optional) - empty property
-+ - The operating system can use the memory in this region with the
-+ limitation that the device driver(s) owning the region need to be
-+ able to reclaim it back. Typically that means that the operating
-+ system can use that region to store volatile or cached data that
-+ can be otherwise regenerated or migrated elsewhere.
-+
-+Linux implementation note:
-+- If a "linux,cma-default" property is present, then Linux will use the
-+ region for the default pool of the contiguous memory allocator.
-+
-+Device node references to reserved memory
-+-----------------------------------------
-+Regions in the /reserved-memory node may be referenced by other device
-+nodes by adding a memory-region property to the device node.
-+
-+memory-region (optional) - phandle, specifier pairs to children of /reserved-memory
-+
-+Example
-+-------
-+This example defines 3 contiguous regions are defined for Linux kernel:
-+one default of all device drivers (named linux,cma@72000000 and 64MiB in size),
-+one dedicated to the framebuffer device (named framebuffer@78000000, 8MiB), and
-+one for multimedia processing (named multimedia-memory@77000000, 64MiB).
-+
-+/ {
-+ #address-cells = <1>;
-+ #size-cells = <1>;
-+
-+ memory {
-+ reg = <0x40000000 0x40000000>;
-+ };
-+
-+ reserved-memory {
-+ #address-cells = <1>;
-+ #size-cells = <1>;
-+ ranges;
-+
-+ /* global autoconfigured region for contiguous allocations */

-+ reusable;
-+ size = <0x4000000>;

-Subject: [PATCH 056/182] spmi: Add MSM PMIC Arbiter SPMI controller
-
-Qualcomm's PMIC Arbiter SPMI controller functions as a bus master and
-is used to communication with one or more PMIC (slave) devices on the
-SPMI bus. The PMIC Arbiter is actually a hardware wrapper around the
-SPMI controller that provides concurrent and autonomous PMIC access
-to various entities that need to communicate with the PMIC.
-
-The SPMI controller hardware handles all of the SPMI bus activity (bus
-arbitration, sequence start condition, transmission of frames, etc).
-This software driver uses the PMIC Arbiter register interface to
-initiate command sequences on the SPMI bus. The status register is
-read to determine when the command sequence has completed and whether
-or not it completed successfully.

-Subject: [PATCH 057/182] spmi: pmic_arb: add support for interrupt handling
-
-The Qualcomm PMIC Arbiter, in addition to being a basic SPMI controller,
-also implements interrupt handling for slave devices. Note, this is
-outside the scope of SPMI, as SPMI leaves interrupt handling completely
-unspecified.
-
-Extend the driver to provide a irq_chip implementation and chained irq
-handling which allows for these interrupts to be used.

-Subject: [PATCH 060/182] i2c: qup: New bus driver for the Qualcomm QUP I2C
- controller
-
-This bus driver supports the QUP i2c hardware controller in the Qualcomm SOCs.
-The Qualcomm Universal Peripheral Engine (QUP) is a general purpose data path
-engine with input/output FIFOs and an embedded i2c mini-core. The driver
-supports FIFO mode (for low bandwidth applications) and block mode (interrupt
-generated for each block-size data transfer).

-+Required properties:
-+ - compatible: Should be:
-+ * "qcom,i2c-qup-v1.1.1" for 8660, 8960 and 8064.
-+ * "qcom,i2c-qup-v2.1.1" for 8974 v1.
-+ * "qcom,i2c-qup-v2.2.1" for 8974 v2 and later.
-+ - reg: Should contain QUP register address and length.
-+ - interrupts: Should contain I2C interrupt.
-+
-+ - clocks: A list of phandles + clock-specifiers, one for each entry in
-+ clock-names.
-+ - clock-names: Should contain:
-+ * "core" for the core clock
-+ * "iface" for the AHB clock
-+
-+ - #address-cells: Should be <1> Address cells for i2c device address
-+ - #size-cells: Should be <0> as i2c addresses have no size component
-+
-+Optional properties:
-+ - clock-frequency: Should specify the desired i2c bus clock frequency in Hz,
-+ defaults to 100kHz if omitted.
-+
-+Child nodes should conform to i2c bus binding.

-+Qualcomm Universal Peripheral (QUP) Serial Peripheral Interface (SPI)
-+
-+The QUP core is an AHB slave that provides a common data path (an output FIFO
-+and an input FIFO) for serial peripheral interface (SPI) mini-core.
-+
-+SPI in master mode supports up to 50MHz, up to four chip selects, programmable
-+data path from 4 bits to 32 bits and numerous protocol variants.
-+
-+Required properties:
-+- compatible: Should contain "qcom,spi-qup-v2.1.1" or "qcom,spi-qup-v2.2.1"
-+- reg: Should contain base register location and length
-+- interrupts: Interrupt number used by this controller
-+
-+- clocks: Should contain the core clock and the AHB clock.
-+- clock-names: Should be "core" for the core clock and "iface" for the
-+ AHB clock.
-+
-+- #address-cells: Number of cells required to define a chip select
-+ address on the SPI bus. Should be set to 1.
-+- #size-cells: Should be zero.
-+
-+Optional properties:
-+- spi-max-frequency: Specifies maximum SPI clock frequency,
-+ Units - Hz. Definition as per
-+ Documentation/devicetree/bindings/spi/spi-bus.txt
-+
-+SPI slave nodes must be children of the SPI master node and can contain
-+properties described in Documentation/devicetree/bindings/spi/spi-bus.txt
-+
-+Example:
-+
-+ spi_8: spi@f9964000 { /* BLSP2 QUP2 */
-+
-+ compatible = "qcom,spi-qup-v2";
-+ #address-cells = <1>;
-+ #size-cells = <0>;
-+ reg = <0xf9964000 0x1000>;
-+ interrupts = <0 102 0>;
-+ spi-max-frequency = <19200000>;
-+
-+ clocks = <&gcc GCC_BLSP2_QUP2_SPI_APPS_CLK>, <&gcc GCC_BLSP2_AHB_CLK>;
-+ clock-names = "core", "iface";
-+
-+ pinctrl-names = "default";
-+ pinctrl-0 = <&spi8_default>;
-+
-+ device@0 {
-+ compatible = "arm,pl022-dummy";
-+ #address-cells = <1>;
-+ #size-cells = <1>;
-+ reg = <0>; /* Chip select 0 */
-+ spi-max-frequency = <19200000>;
-+ spi-cpol;
-+ };
-+
-+ device@1 {
-+ compatible = "arm,pl022-dummy";
-+ #address-cells = <1>;
-+ #size-cells = <1>;
-+ reg = <1>; /* Chip select 1 */
-+ spi-max-frequency = <9600000>;
-+ spi-cpha;

-+
-+ device@2 {

-Subject: [PATCH 074/182] spi: qup: Depend on ARCH_QCOM
-
-Commit 8fc1b0f87d9f ("ARM: qcom: Split Qualcomm support into legacy and
-multiplatform") removed Kconfig symbol ARCH_MSM_DT. But that commit
-left one (optional) dependency on ARCH_MSM_DT untouched.
-
-Three Kconfig symbols used to depend on ARCH_MSM_DT: ARCH_MSM8X60,
-ARCH_MSM8960, and ARCH_MSM8974. These three symbols now depend on
-ARCH_QCOM. So it appears this driver needs to depend on ARCH_QCOM too.

-Subject: [PATCH 079/182] clk: qcom: Add basic support for APQ8064 global
- clock controller clocks
-
-The APQ8064 and MSM8960 share a significant amount of clock data and
-code between the two SoCs. Rather than duplicating the data we just add
-support for a unqiue APQ8064 clock table into the MSM8960 code.
-
-For now add just enough clocks to get a basic serial port going on an
-APQ8064 device.

- specific drivers
-
-Based on earlier thread "https://lkml.org/lkml/2013/10/7/662" and
-discussion at Kernel Summit'2013, it was agreed to create
-'driver/soc' for drivers which are quite SOC specific.
-
-Further discussion on the subject is in response to
-the earlier version of the patch is here:

-+QCOM GSBI (General Serial Bus Interface) Driver
-+
-+The GSBI controller is modeled as a node with zero or more child nodes, each
-+representing a serial sub-node device that is mux'd as part of the GSBI
-+configuration settings. The mode setting will govern the input/output mode of
-+the 4 GSBI IOs.
-+
-+Required properties:
-+- compatible: must contain "qcom,gsbi-v1.0.0" for APQ8064/IPQ8064
-+- reg: Address range for GSBI registers
-+- clocks: required clock
-+- clock-names: must contain "iface" entry
-+- qcom,mode : indicates MUX value for configuration of the serial interface.
-+ Please reference dt-bindings/soc/qcom,gsbi.h for valid mux values.
-+
-+Optional properties:
-+- qcom,crci : indicates CRCI MUX value for QUP CRCI ports. Please reference
-+ dt-bindings/soc/qcom,gsbi.h for valid CRCI mux values.
-+
-+Required properties if child node exists:
-+- #address-cells: Must be 1
-+- #size-cells: Must be 1
-+- ranges: Must be present
-+
-+Properties for children:
-+
-+A GSBI controller node can contain 0 or more child nodes representing serial
-+devices. These serial devices can be a QCOM UART, I2C controller, spi
-+controller, or some combination of aforementioned devices.
-+
-+See the following for child node definitions:
-+Documentation/devicetree/bindings/i2c/qcom,i2c-qup.txt
-+Documentation/devicetree/bindings/spi/qcom,spi-qup.txt

-Subject: [PATCH 093/182] ARM: dts: qcom: Update msm8660 device trees
-
-* Move SoC peripherals into an SoC container node
-* Move serial enabling into board file (qcom-msm8660-surf.dts)
-* Cleanup cpu node to match binding spec, enable-method and compatible
- should be per cpu, not part of the container
-* Add GSBI node and configuration of GSBI controller

-Subject: [PATCH 097/182] ARM: debug: qcom: make UART address selection
- configuration option
-
-Separate Qualcomm low-level debugging UART to two options.
-
-DEBUG_MSM_UART is used in earlier non-multi platform arches,
-like MSM7X00A, QSD8X50 and MSM7X30.
-
-DEBUG_QCOM_UARTDM is used in multi-plafrom arches and have
-embedded data mover.
-
-Make DEBUG_UART_PHYS and DEBUG_UART_BASE user adjustable by
-Kconfig menu.

-Subject: [PATCH 106/182] clk: qcom: Properly support display clocks on
- msm8974
-
-The display clocks all source from dedicated phy PLLs within their
-respective multimedia hardware block. Hook up these PLLs to the
-display clocks with the appropriate parent mappings, clock flags,
-and the appropriate clock ops. This should allow the display
-clocks to work once the appropriate phy PLL driver registers their
-PLL clocks.

-Subject: [PATCH 109/182] libahci: Allow drivers to override start_engine
-
-Allwinner A10 and A20 ARM SoCs have an AHCI sata controller which needs a
-special register to be poked before starting the DMA engine.
-
-This register gets reset on an ahci_stop_engine call, so there is no other
-place then ahci_start_engine where this poking can be done.
-
-This commit allows drivers to override ahci_start_engine behavior for use by
-the Allwinner AHCI driver (and potentially other drivers in the future).

-Date: Tue, 21 Jan 2014 16:22:51 -0500
-Subject: [PATCH 113/182] ata: delete non-required instances of include
- <linux/init.h>
-
-None of these files are actually using any __init type directives
-and hence don't need to include <linux/init.h>. Most are just a
-left over from __devinit and __cpuinit removal, or simply due to
-code getting copied from one driver to the next.

-Date: Sat, 22 Feb 2014 16:53:34 +0100
-Subject: [PATCH 114/182] ahci-platform: "Library-ise" ahci_probe
- functionality
-
-ahci_probe consists of 3 steps:
-1) Get resources (get mmio, clks, regulator)
-2) Enable resources, handled by ahci_platform_enable_resouces
-3) The more or less standard ahci-host controller init sequence
-
-This commit refactors step 1 and 3 into separate functions, so the platform
-drivers for AHCI implementations which need a specific order in step 2,
-and / or need to do some custom register poking at some time, can re-use
-ahci-platform.c code without needing to copy and paste it.
-
-Note that ahci_platform_init_host's prototype takes the 3 non function
-members of ahci_platform_data as arguments, the idea is that drivers using
-the new exported utility functions will not use ahci_platform_data at all,
-and hopefully in the future ahci_platform_data can go away entirely.
-
-tj: Minor comment formatting updates.

-Subject: [PATCH 120/182] ahci_platform: Drop support for imx53-ahci platform
- device type
-
-Since the 3.13 release the ahci_imx driver has proper devicetree enabled
-support for ahci on imx53 and that is used instead of the old board file
-created imx53-ahci platform device.
-
-Note this patch also complete drops the id-table, an id-table is not needed
-for a single id platform driver, the name field in the driver struct suffices.
-
-And the code already has an explicit "MODULE_ALIAS("platform:ahci");" so the
-id-table is not needed for that either.

-devm_ioremap_resource() returns a pointer to the remapped memory or

-ahci_platform_get_resources() accordingly.

- method handling
-
-Looking at ST SPEAr1340 AHCI code (the only user of the deprecated
-pdata->suspend and pdata->resume) it is obvious the we should return
-after calling pdata->suspend() only if the function have returned
-non-zero return value. The code has been broken since commit 1e70c2
-("ata/ahci_platform: Add clock framework support"). Fix it.

-Subject: [PATCH 125/182] clk: qcom: Add support for IPQ8064's global clock
- controller (GCC)
-
-Add a driver for the global clock controller found on IPQ8064 based
-platforms. This should allow most non-multimedia device drivers to probe
-and control their clocks.
-
-This is currently missing clocks for USB HSIC and networking devices.

-Subject: [PATCH 126/182] clk: Add safe switch hook
-
-Sometimes clocks can't accept their parent source turning off
-while the source is reprogrammed to a different rate. Most
-notably CPU clocks require a way to switch away from the current
-PLL they're running on, reprogram that PLL to a new rate, and
-then switch back to the PLL with the new rate once they're done.
-Add a hook that drivers can implement allowing them to return a
-'safe parent' that they can switch their parent to while the
-upstream source is reprogrammed to support this.

-Subject: [PATCH 129/182] clk: qcom: Add support for NSS/GMAC clocks and
- resets
-
-The NSS driver expects one virtual clock that actually represents
-two clocks (one for each UBI32 core). Register the ubi32 core
-clocks and also make a wrapper virtual clock called nss_core_clk
-to be used by the driver. This will properly handle switching the
-rates of both clocks at the same time like how the NSS driver
-expects it. Also add the TCM clock and the NSS resets.

-This patch removes the chip select function. Chip select should instead be
-supported using GPIOs, defining the DT entry "cs-gpios", and letting the SPI
-core assert/deassert the chip select as it sees fit.

-+* Qualcomm AHCI SATA Controller
-+
-+SATA nodes are defined to describe on-chip Serial ATA controllers.
-+Each SATA controller should have its own node.
-+
-+Required properties:
-+- compatible : compatible list, contains "qcom,msm-ahci"
-+- interrupts : <interrupt mapping for SATA IRQ>
-+- reg : <registers mapping>
-+- phys : Must contain exactly one entry as specified
-+ in phy-bindings.txt
-+- phy-names : Must be "sata-phy"
-+
-+Required properties for "qcom,ipq806x-ahci" compatible:
-+- clocks : Must contain an entry for each entry in clock-names.
-+- clock-names : Shall be:
-+ "slave_iface" - Fabric port AHB clock for SATA
-+ "iface" - AHB clock
-+ "core" - core clock
-+ "rxoob" - RX out-of-band clock
-+ "pmalive" - Power Module Alive clock
-+
-+Example:
-+ sata@29000000 {
-+ compatible = "qcom,ipq806x-ahci", "qcom,msm-ahci";
-+ reg = <0x29000000 0x180>;
-+
-+ interrupts = <0 209 0x0>;
-+
-+ clocks = <&gcc SFAB_SATA_S_H_CLK>,
-+ <&gcc SATA_H_CLK>,
-+ <&gcc SATA_A_CLK>,
-+ <&gcc SATA_RXOOB_CLK>,
-+ <&gcc SATA_PMALIVE_CLK>;
-+ clock-names = "slave_iface", "iface", "core",
-+ "rxoob", "pmalive";
-+
-+ phys = <&sata_phy>;
-+ phy-names = "sata-phy";

-+- compatible: must contain "qcom,tcsr" for IPQ806x
-+- reg: Address range for TCSR registers
-+
-+Optional properties:
-+- qcom,usb-ctrl-select : indicates USB port type selection. Please reference
-+ dt-bindings/soc/qcom,tcsr.h for valid USB port selection values.

-
-This config exists entirely to hide the cpufreq menu from the
-kernel configuration unless a platform has selected it. Nothing
-is actually built if this config is 'Y' and it just leads to more
-patches that add a select under a platform Kconfig so that some
-other CPUfreq option can be chosen. Let's remove the option so
-that we can always enable CPUfreq drivers on ARM platforms.

-Subject: [PATCH 164/182] ARM: Add Krait L2 register accessor functions
-
-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.

-Subject: [PATCH 165/182] clk: qcom: Add support for muxes, dividers, and mux
- dividers
-
-The Krait CPU clocks are made up of muxes and dividers with a
-handful of sources. Add a set of clk_ops that allow us to
-configure these clocks so we can support CPU frequency scaling on
-Krait CPUs.
-
-Based on code originally written by Saravana Kannan.

-Subject: [PATCH 169/182] clk: qcom: Add support for Krait clocks
-
-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.

-Subject: [PATCH 172/182] cpufreq: Add a cpufreq-krait based on cpufreq-cpu0
-
-Krait processors have individual clocks for each CPU that can
-scale independently from one another. cpufreq-cpu0 is fairly
-close to this, but assumes that there is only one clock for all
-CPUs. Add a driver to support the Krait configuration.
-
-TODO: Merge into cpufreq-cpu0? Or make generic?

-Subject: [PATCH 177/182] dmaengine: Add QCOM ADM DMA driver
-
-Add the DMA engine driver for the QCOM Application Data Mover (ADM) DMA
-controller found in the MSM8960 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.

-+QCOM ADM DMA Controller
-+
-+Required properties:
-+- compatible: must contain "qcom,adm" for IPQ/APQ8064 and MSM8960
-+- reg: Address range for DMA registers
-+- interrupts: Should contain one interrupt shared by all channels
-+- #dma-cells: must be <2>. First cell denotes the channel number. Second cell
-+ denotes CRCI (client rate control interface) flow control assignment.
-+- clocks: Should contain the core clock and interface clock.
-+- clock-names: Must contain "core" for the core clock and "iface" for the
-+ interface clock.
-+- resets: Must contain an entry for each entry in reset names.
-+- reset-names: Must include the following entries:
-+ - clk
-+ - c0
-+ - c1
-+ - c2
-+- qcom,ee: indicates the security domain identifier used in the secure world.
-+
-+Example:
-+ adm_dma: dma@18300000 {
-+ compatible = "qcom,adm";
-+ reg = <0x18300000 0x100000>;
-+ interrupts = <0 170 0>;
-+ #dma-cells = <2>;
-+
-+ clocks = <&gcc ADM0_CLK>, <&gcc ADM0_PBUS_CLK>;
-+ clock-names = "core", "iface";
-+
-+ resets = <&gcc ADM0_RESET>,
-+ <&gcc ADM0_C0_RESET>,
-+ <&gcc ADM0_C1_RESET>,
-+ <&gcc ADM0_C2_RESET>;
-+ reset-names = "clk", "c0", "c1", "c2";
-+ qcom,ee = <0>;
-+ };
-+
-+DMA clients must use the format descripted in the dma.txt file, using a three
-+cell specifier for each channel.
-+
-+Each dmas request consists of 3 cells:
-+ 1. phandle pointing to the DMA controller
-+ 2. channel number
-+ 3. CRCI assignment, if applicable. If no CRCI flow control is required, use 0.
-+
-+Example:
-+
-+ spi4: spi@1a280000 {
-+ status = "ok";
-+ spi-max-frequency = <50000000>;
-+
-+ pinctrl-0 = <&spi_pins>;
-+ pinctrl-names = "default";
-+
-+ cs-gpios = <&qcom_pinmux 20 0>;
-+
-+ dmas = <&adm_dma 6 9>,
-+ <&adm_dma 5 10>;
-+ dma-names = "rx", "tx";
-+ };

-Subject: [PATCH 179/182] spi: qup: Add DMA capabilities
-
-This patch adds DMA capabilities to the spi-qup driver. If DMA channels are
-present, the QUP will use DMA instead of block mode for transfers to/from SPI
-peripherals for transactions larger greater than the length of a block.

Patches in the ipq806x/patches folder were out of tree in v3.14. The newest patch at the time was from June, so we can safely assume that either the patches have been merged, or they have been rejected for a good reason. If patches are seen missing, we'll cherry-pick them on a per-needed basis. This new kernel have been tested on AP148, which seems to works fine.
