ipq806x: update target to v3.18

Browse source 
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.

From 3cdba35369b404875849008ea97cf1705e6060ed Mon Sep 17 00:00:00 2001
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.

Subject: [PATCH 002/182] ARM: msm: Remove pen_release usage
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 003/182] ARM: msm: kill off hotplug.c
Right now hotplug.c only really implements msm_cpu_die as a wfi. Just
move that implementation into platsmp.c. At the same time we use the
existing wfi() instead of inline asm.

Subject: [PATCH 006/182] clocksource: qcom: split building of legacy vs
multiplatform support
The majority of the clocksource code for the Qualcomm platform is shared
between newer (multiplatform) and older platforms. However there is a bit
of code that isn't, so only build it for the appropriate config.

From 48f17325fef9cbebc5cb39aa78f4c1caff5d7b16 Mon Sep 17 00:00:00 2001
From: Stephen Boyd <sboyd@codeaurora.org>
Date: Wed, 30 Oct 2013 18:21:09 -0700
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.

Subject: [PATCH 009/182] ARM: qcom: Re-organize platsmp to make it extensible
This makes it easy to add SMP support for new devices by keying
on a device node for the release sequence. We add the
enable-method property for the cpus property to specify that we
want to use the gcc-msm8660 release sequence (which is going to
look for the global clock controller device node to map some
Scorpion specific power and control registers). We also remove
the nr_cpus detection code as that is done generically in the DT
CPU detection code.

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.

Scorpion and Krait don't use the spin-table enable-method.
Instead they rely on mmio register accesses to enable power and

+The KPSS ACC provides clock, power domain, and reset control to a Krait CPU.
+There is one ACC register region per CPU within the KPSS remapped region as

+SPM AVS Wrapper 2 (SAW2)
+
+The SAW2 is a wrapper around the Subsystem Power Manager (SPM) and the
+Adaptive Voltage Scaling (AVS) hardware. The SPM is a programmable
+micro-controller that transitions a piece of hardware (like a processor or
+subsystem) into and out of low power modes via a direct connection to
+the PMIC. It can also be wired up to interact with other processors in the
+system, notifying them when a low power state is entered or exited.

Subject: [PATCH 019/182] gpio: msm: switch Kconfig to ARCH_QCOM depends
We've split Qualcomm MSM support into legacy and multiplatform. The gpio
msm-v2 driver is only relevant on the multiplatform supported SoCs so
switch the Kconfig depends to ARCH_QCOM.

This patch fixes a number of errors with the QUP block transfer mode. Errors
manifested themselves as input underruns, output overruns, and timed out
transactions.
The block mode does not require the priming that occurs in FIFO mode. At the
moment that the QUP is placed into the RUN state, the QUP will immediately raise
an interrupt if the request is a write. Therefore, there is no need to prime
the pump.
In addition, the block transfers require that whole blocks of data are
read/written at a time. The last block of data that completes a transaction may
contain less than a full blocks worth of data.
Each block of data results in an input/output service interrupt accompanied with
a input/output block flag set. Additional block reads/writes require clearing
of the service flag. It is ok to check for additional blocks of data in the
ISR, but you have to ack every block you transfer. Imbalanced acks result in
early return from complete transactions with pending interrupts that still have
to be ack'd. The next transaction can be affected by these interrupts.
Transactions are deemed complete when the MAX_INPUT or MAX_OUTPUT flag are set.
Changes from v2:
- Added in additional completion check so that transaction done is not
prematurely signaled.
- Fixed various review comments.
Changes from v1:
- Split out read/write block function.
- Removed extraneous checks for transfer length

Subject: [PATCH 025/182] pinctrl: msm: drop wake_irqs bitmap
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.

Subject: [PATCH 026/182] pinctrl: msm: Silence recursive lockdep warning
If a driver calls enable_irq_wake() on a gpio turned interrupt
from the msm pinctrl driver we'll get a lockdep warning like so:
=============================================
[ 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
4 locks held by modprobe/52:

#3: (&(&pctrl->lock)->rlock){......}, at: [<c04bb4b8>] msm_gpio_irq_set_wake+0x20/0xa8
Silence it by putting the gpios into their own lock class.

Subject: [PATCH 032/182] pinctrl: msm: Simplify msm_config_reg() and callers
We don't need to check for a negative reg here because reg is
always the same and is always non-negative. Also, collapse the
switch statement down for the duplicate cases.

Commit 051a58b4622f0e1b732acb750097c64bc00ddb93
"pinctrl: msm: Simplify msm_config_reg() and callers"
removed the local "reg" variable in the msm_config_reg()
function, but the earlier
commit ed118a5fd951bd2def8249ee251842c4f81fe4bd
"pinctrl-msm: Support output-{high,low} configuration"
introduced a new switchclause using it.
Fix this up by removing the offending register assignment.

Subject: [PATCH 036/182] pinctrl: msm: Correct interrupt code for TLMM v2
Acking interrupts are done differently between on v2 and v3, so add an extra
attribute to the pingroup struct to let the platform definitions control this.
Also make sure to start dual edge detection by detecting the rising edge.

Subject: [PATCH 039/182] pinctrl: msm8x74: make Kconfig dependency more
strict
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,
+ pcie1_clk_req, pcie2_rst, pcie2_prsnt, pcie2_pwren_n, pcie2_pwren,
+ pcie2_pwrflt, pcie2_clk_req, pcie3_rst, pcie3_prsnt, pcie3_pwren_n,
+ pcie3_pwren, pcie3_pwrflt, pcie3_clk_req, ps_hold
+
+Example:
+
+ pinmux: pinctrl@800000 {
+ compatible = "qcom,ipq8064-pinctrl";
+ reg = <0x800000 0x4000>;
+
+ gpio-controller;
+ #gpio-cells = <2>;

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 */
+ linux,cma {
+ compatible = "shared-dma-pool";
+ reusable;
+ size = <0x4000000>;
+ alignment = <0x2000>;
+ linux,cma-default;
+ };
+
+ display_reserved: framebuffer@78000000 {
+ reg = <0x78000000 0x800000>;
+ };
+
+ multimedia_reserved: multimedia@77000000 {
+ compatible = "acme,multimedia-memory";
+ reg = <0x77000000 0x4000000>;
+ };
+ };
+
+ /* ... */
+

+ memory-region = <&display_reserved>;

Subject: [PATCH 054/182] of: only scan for reserved mem when fdt present
When the reserved memory patches hit -next, several legacy (non-DT) boot
failures were detected and bisected down to that commit. There needs to
be some sanity checking whether a DT is even present before parsing the
reserved ranges.

Subject: [PATCH 055/182] spmi: Linux driver framework for SPMI
System Power Management Interface (SPMI) is a specification
developed by the MIPI (Mobile Industry Process Interface) Alliance
optimized for the real time control of Power Management ICs (PMIC).
SPMI is a two-wire serial interface that supports up to 4 master
devices and up to 16 logical slaves.
The framework supports message APIs, multiple busses (1 controller
per bus) and multiple clients/slave devices per controller.

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 059/182] spmi: pm: drop bus-level PM suspend/resume routines
SPMI defines the behavior of a device in the "SLEEP" state as being
"user-defined or specified by the device manufacturer". Without
clearly-defined bus-level semantics for low-power states, push the
responsibility of transitioning a device into/out of "SLEEP" into SPMI
device drivers.

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).

+Qualcomm Universal Peripheral (QUP) I2C controller
+
+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.
+
+Example:
+
+ i2c@f9924000 {
+ compatible = "qcom,i2c-qup-v2.2.1";
+ reg = <0xf9924000 0x1000>;

+ clock-names = "core", "iface";
+
+ clock-frequency = <355000>;
+
+ #address-cells = <1>;
+ #size-cells = <0>;

Subject: [PATCH 065/182] spi: Add Qualcomm QUP SPI controller support
Qualcomm Universal Peripheral (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.

+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 {
+ compatible = "arm,pl022-dummy";
+ #address-cells = <1>;
+ #size-cells = <1>;
+ reg = <2>; /* Chip select 2 */
+ spi-max-frequency = <19200000>;

transfer speed
Set master->max_speed_hz then spi core will handle checking transfer speed.
So we can remove the same checking in this driver.
Also remove checking spi->chip_select in spi_qup_setup(), the checking is done
by spi core.

Subject: [PATCH 073/182] spi: qup: Get rid of using struct spi_qup_device
Current code uses struct spi_qup_device to store spi->mode and spi->chip_select
settings. We can get these settings in spi_qup_transfer_one and spi_qup_set_cs
without using struct spi_qup_device. Refactor the code a bit to remove
spi_qup_setup(), spi_qup_cleanup(), and struct spi_qup_device.

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.

Most of the probe code is the same between all the different
clock controllers. Consolidate the code into a common.c file.
This makes changes to the common probe parts easier and reduces
chances for bugs.

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.

From e1f51c2d41c8936b8383cf4ac53c1ff05b0e2e2f Mon Sep 17 00:00:00 2001
From: Stephen Boyd <sboyd@codeaurora.org>
Date: Thu, 27 Feb 2014 12:54:24 -0800
Subject: [PATCH 081/182] ARM: config: Add qcom_defconfig
Add a defconfig for mach-qcom platforms (copied from msm_defconfig).
Although these platforms are part of the multi-platform kernel, it's
useful to have a stripped down version of the defconfig that just
selects the DT based Qualcomm platforms and drivers.

Subject: [PATCH 083/182] soc: Introduce drivers/soc place-holder for SOC
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:

Subject: [PATCH 084/182] soc: qcom: Add GSBI driver
The GSBI (General Serial Bus Interface) driver controls the overarching
configuration of the shared serial bus infrastructure on APQ8064, IPQ8064, and
earlier QCOM processors. The GSBI supports UART, I2C, SPI, and UIM
functionality in various combinations.

+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

Subject: [PATCH 092/182] ARM: dts: qcom: Update msm8960 device trees
* Move SoC peripherals into an SoC container node
* Move serial enabling into board file (qcom-msm8960-cdp.dts)
* Cleanup cpu node to match binding spec, enable-method and compatible
should be per cpu, not part of the container
* Drop interrupts property from l2-cache node as its not part of the
binding spec
* 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.
