Merge tag 'pinctrl-v4.2-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl 

Pull pin control updates from Linus Walleij:
 "Here is the bulk of pin control changes for the v4.2 series: Quite a
  lot of new SoC subdrivers and two new main drivers this time, apart
  from that business as usual.

  Details:

  Core functionality:
   - Enable exclusive pin ownership: it is possible to flag a pin
     controller so that GPIO and other functions cannot use a single pin
     simultaneously.

  New drivers:
   - NXP LPC18xx System Control Unit pin controller
   - Imagination Pistachio SoC pin controller

  New subdrivers:
   - Freescale i.MX7d SoC
   - Intel Sunrisepoint-H PCH
   - Renesas PFC R8A7793
   - Renesas PFC R8A7794
   - Mediatek MT6397, MT8127
   - SiRF Atlas 7
   - Allwinner A33
   - Qualcomm MSM8660
   - Marvell Armada 395
   - Rockchip RK3368

  Cleanups:
   - A big cleanup of the Marvell MVEBU driver rectifying it to
     correspond to reality
   - Drop platform device probing from the SH PFC driver, we are now a
     DT only shop for SuperH
   - Drop obsolte multi-platform check for SH PFC
   - Various janitorial: constification, grammar etc

  Improvements:
   - The AT91 GPIO portions now supports the set_multiple() feature
   - Split out SPI pins on the Xilinx Zynq
   - Support DTs without specific function nodes in the i.MX driver"

CSR SiRFatlas7 GPIO controller bindings



Required properties:

- compatible	: "sirf,atlas7-gpio"

- reg		: Address range of the pinctrl registers

- interrupts	: Interrupts used by every GPIO group

- gpio-banks	: How many gpio banks on this controller

- gpio-controller : Indicates this device is a GPIO controller

- interrupt-controller  : Marks the device node as an interrupt controller



The GPIO controller also acts as an interrupt controller. It uses the default

two cells specifier as described in Documentation/devicetree/bindings/

interrupt-controller/interrupts.txt.



Example:



	gpio_0: gpio_mediam@17040000 {

		compatible = "sirf,atlas7-gpio";

		reg = <0x17040000 0x1000>;

		interrupts = <0 13 0>, <0 14 0>;



		#gpio-cells = <2>;

		#interrupt-cells = <2>;



		gpio-controller;

		interrupt-controller;



		gpio-banks = <2>;

		gpio-ranges = <&pinctrl 0 0 0>,

				<&pinctrl 32 0 0>;

		gpio-ranges-group-names = "lvds_gpio_grp",

					"uart_nand_gpio_grp";

	};



	leds {

		compatible = "gpio-leds";



		led1 {

			gpios = <&gpio_1 15 0>;

			...

		};



		led2 {

			gpios = <&gpio_2 34 0>;

			...

		};

	};



Please refer to gpio.txt in this directory for details of the common

gpio properties used by devices.

Imagination Technologies Pistachio SoC pin controllers

======================================================



The pin controllers on Pistachio are a combined GPIO controller, (GPIO)

interrupt controller, and pinmux + pinconf device. The system ("east") pin

controller on Pistachio has 99 pins, 90 of which are MFIOs which can be

configured as GPIOs. The 90 GPIOs are divided into 6 banks of up to 16 GPIOs

each. The GPIO banks are represented as sub-nodes of the pad controller node.



Please refer to pinctrl-bindings.txt, ../gpio/gpio.txt, and

../interrupt-controller/interrupts.txt for generic information regarding

pin controller, GPIO, and interrupt bindings.



Required properties for pin controller node:

--------------------------------------------

 - compatible: "img,pistachio-system-pinctrl".

 - reg: Address range of the pinctrl registers.



Required properties for GPIO bank sub-nodes:

--------------------------------------------

 - interrupts: Interrupt line for the GPIO bank.

 - gpio-controller: Indicates the device is a GPIO controller.

 - #gpio-cells: Must be two. The first cell is the GPIO pin number and the

   second cell indicates the polarity. See <dt-bindings/gpio/gpio.h> for

   a list of possible values.

 - interrupt-controller: Indicates the device is an interrupt controller.

 - #interrupt-cells: Must be two. The first cell is the GPIO pin number and

   the second cell encodes the interrupt flags. See

   <dt-bindings/interrupt-controller/irq.h> for a list of valid flags.



Note that the N GPIO bank sub-nodes *must* be named gpio0, gpio1, ... gpioN-1.



Required properties for pin configuration sub-nodes:

----------------------------------------------------

 - pins: List of pins to which the configuration applies. See below for a

   list of possible pins.



Optional properties for pin configuration sub-nodes:

----------------------------------------------------

 - function: Mux function for the specified pins. This is not applicable for

   non-MFIO pins. See below for a list of valid functions for each pin.

 - bias-high-impedance: Enable high-impedance mode.

 - bias-pull-up: Enable weak pull-up.

 - bias-pull-down: Enable weak pull-down.

 - bias-bus-hold: Enable bus-keeper mode.

 - drive-strength: Drive strength in mA. Supported values: 2, 4, 8, 12.

 - input-schmitt-enable: Enable Schmitt trigger.

 - input-schmitt-disable: Disable Schmitt trigger.

 - slew-rate: Slew rate control. 0 for slow, 1 for fast.
