Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input 

Pull input updates from Dmitry Torokhov:
 "Updates for the input subsystem.  This contains the following new
  drivers promised in the last merge window:

   - driver for touchscreen controller found in Surface 3
   - driver for Pegasus Notetaker tablet
   - driver for Atmel Captouch Buttons
   - driver for Raydium I2C touchscreen controllers
   - powerkey driver for HISI 65xx SoC

  plus a few fixes"

Device tree bindings for Atmel capacitive touch device, typically

an Atmel touch sensor connected to AtmegaXX MCU running firmware

based on Qtouch library.



The node for this device must be a child of a I2C controller node, as the

device communicates via I2C.



Required properties:



	compatible:	Must be "atmel,captouch".

	reg:		The I2C slave address of the device.

	interrupts:	Property describing the interrupt line the device

			is connected to. The device only has one interrupt

			source.

	linux,keycodes:	Specifies an array of numeric keycode values to

			be used for reporting button presses. The array can

			contain up to 8 entries.



Optional properties:



	autorepeat:	Enables the Linux input system's autorepeat

			feature on the input device.



Example:



	atmel-captouch@51 {

		compatible = "atmel,captouch";

		reg = <0x51>;

		interrupt-parent = <&tlmm>;

		interrupts = <67 IRQ_TYPE_EDGE_FALLING>;

		linux,keycodes = <BTN_0>, <BTN_1>,

			<BTN_2>, <BTN_3>,

			<BTN_4>, <BTN_5>,

			<BTN_6>, <BTN_7>;

		autorepeat;

	};

Raydium I2C touchscreen



Required properties:

- compatible: must be "raydium,rm32380"

- reg: The I2C address of the device

- interrupt-parent: the phandle for the interrupt controller

- interrupts: interrupt to which the chip is connected

    See ../interrupt-controller/interrupts.txt

Optional properties:

- avdd-supply: analog power supply needed to power device

- vccio-supply: IO Power source

- reset-gpios: reset gpio the chip is connected to.



Example:

	touchscreen@39 {

		compatible = "raydium,rm32380";

		reg = <0x39>;

		interrupt-parent = <&gpio>;

		interrupts = <0x0 IRQ_TYPE_EDGE_FALLING>;

	};
