This is the bulk of pin control changes for the v4.3 development 

cycle
 
 Core changes:
 
 - It is possible configure groups in debugfs.
 
 - Consolidation of chained IRQ handler install/remove replacing
   all call sites where irq_set_handler_data() and
   irq_set_chained_handler() were done in succession with a
   combined call to irq_set_chained_handler_and_data(). This
   series was created by Thomas Gleixner after the problem was
   observed by Russell King.
 
 - Tglx also made another series of patches switching
   __irq_set_handler_locked() for irq_set_handler_locked() which
   is way cleaner.
 
 - Tglx also wrote a good bunch of patches to make use of
   irq_desc_get_xxx() accessors and avoid looking up irq_descs
   from IRQ numbers. The goal is to get rid of the irq number
   from the handlers in the IRQ flow which is nice.
 
 Driver feature enhancements:
 
 - Power management support for the SiRF SoC Atlas 7.
 
 - Power down support for the Qualcomm driver.
 
 - Intel Cherryview and Baytrail: switch drivers to use raw
   spinlocks in IRQ handlers to play nice with the realtime
   patch set.
 
 - Rework and new modes handling for Qualcomm SPMI-MPP.
 
 - Pinconf power source config for SH PFC.
 
 New drivers and subdrivers:
 
 - A new driver for Conexant Digicolor CX92755.
 
 - A new driver for UniPhier PH1-LD4, PH1-Pro4, PH1-sLD8,
   PH1-Pro5, ProXtream2 and PH1-LD6b SoC pin control support.
 
 - Reverse-egineered the S/PDIF settings for the Allwinner
   sun4i driver.
 
 - Support for Qualcomm Technologies QDF2xxx ARM64 SoCs
 
 - A new Freescale i.mx6ul subdriver.
 
 Cleanup:
 
 - Remove platform data support in a number of SH PFC
   subdrivers.

Pull pin control updates from Linus Walleij:
 "This is the bulk of pin control changes for the v4.3 development
  cycle.

  Like with GPIO it's a lot of stuff.  If my subsystems are any sign of
  the overall tempo of the kernel v4.3 will be a gigantic diff.

[ It looks like 4.3 is calmer than 4.2 in most other subsystems, but
  we'll see - Linus ]

GPIO and interrupt controller
-----------------------------
This hardware also acts as a GPIO controller and an interrupt
controller.
Consumers that would want to refer to one or the other (or both)
should provide through the usual *-gpios and interrupts properties a
cell with 3 arguments, first the number of the bank, then the pin
inside that bank, and finally the flags for the GPIO/interrupts.
Example:
xio: gpio@38 {
compatible = "nxp,pcf8574a";
reg = <0x38>;
gpio-controller;
#gpio-cells = <2>;
interrupt-parent = <&pio>;
interrupts = <6 0 IRQ_TYPE_EDGE_FALLING>;
interrupt-controller;
#interrupt-cells = <2>;
};
reg_usb1_vbus: usb1-vbus {
compatible = "regulator-fixed";
regulator-name = "usb1-vbus";
regulator-min-microvolt = <5000000>;
regulator-max-microvolt = <5000000>;
gpio = <&pio 7 6 GPIO_ACTIVE_HIGH>;

Conexant Digicolor CX92755 General Purpose Pin Mapping
This document describes the device tree binding of the pin mapping hardware
modules in the Conexant Digicolor CX92755 SoCs. The CX92755 in one of the
Digicolor series of SoCs.
=== Pin Controller Node ===
Required Properties:
- compatible: Must be "cnxt,cx92755-pinctrl"
- reg: Base address of the General Purpose Pin Mapping register block and the
size of the block.
- gpio-controller: Marks the device node as a GPIO controller.
- #gpio-cells: Must be <2>. The first cell is the pin number and the
second cell is used to specify flags. See include/dt-bindings/gpio/gpio.h
for possible values.
For example, the following is the bare minimum node:
pinctrl: pinctrl@f0000e20 {
compatible = "cnxt,cx92755-pinctrl";
reg = <0xf0000e20 0x100>;
gpio-controller;
#gpio-cells = <2>;
};
As a pin controller device, in addition to the required properties, this node
should also contain the pin configuration nodes that client devices reference,
if any.
For a general description of GPIO bindings, please refer to ../gpio/gpio.txt.
=== Pin Configuration Node ===
Each pin configuration node is a sub-node of the pin controller node and is a
container of an arbitrary number of subnodes, called pin group nodes in this
document.
Please refer to the pinctrl-bindings.txt in this directory for details of the
common pinctrl bindings used by client devices, including the definition of a
"pin configuration node".
=== Pin Group Node ===
A pin group node specifies the desired pin mux for an arbitrary number of
pins. The name of the pin group node is optional and not used.
A pin group node only affects the properties specified in the node, and has no
effect on any properties that are omitted.
The pin group node accepts a subset of the generic pin config properties. For
details generic pin config properties, please refer to pinctrl-bindings.txt
and <include/linux/pinctrl/pinconfig-generic.h>.
Required Pin Group Node Properties:
- pins: Multiple strings. Specifies the name(s) of one or more pins to be
configured by this node. The format of a pin name string is "GP_xy", where x
is an uppercase character from 'A' to 'R', and y is a digit from 0 to 7.
- function: String. Specifies the pin mux selection. Values must be one of:
"gpio", "client_a", "client_b", "client_c"
Example:
pinctrl: pinctrl@f0000e20 {
compatible = "cnxt,cx92755-pinctrl";
reg = <0xf0000e20 0x100>;
uart0_default: uart0_active {
data_signals {
pins = "GP_O0", "GP_O1";
function = "client_b";
};
};
};
uart0: uart@f0000740 {
compatible = "cnxt,cx92755-usart";
...
pinctrl-0 = <&uart0_default>;
pinctrl-names = "default";
};
In the example above, a single pin group configuration node defines the
"client select" for the Rx and Tx signals of uart0. The uart0 node references
that pin configuration node using the &uart0_default phandle.
