      linux,code: true

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;

* Samsung's Keypad Controller device tree bindings

Samsung's Keypad controller is used to interface a SoC with a matrix-type

keypad device. The keypad controller supports multiple row and column lines.

A key can be placed at each intersection of a unique row and a unique column.

The keypad controller can sense a key-press and key-release and report the

event using a interrupt to the cpu.

Required SoC Specific Properties:

- compatible: should be one of the following

  - "samsung,s3c6410-keypad": For controllers compatible with s3c6410 keypad

    controller.

  - "samsung,s5pv210-keypad": For controllers compatible with s5pv210 keypad

    controller.

- reg: physical base address of the controller and length of memory mapped

  region.

- interrupts: The interrupt number to the cpu.

Required Board Specific Properties:

- samsung,keypad-num-rows: Number of row lines connected to the keypad

  controller.

- samsung,keypad-num-columns: Number of column lines connected to the

  keypad controller.

- Keys represented as child nodes: Each key connected to the keypad

  controller is represented as a child node to the keypad controller

  device node and should include the following properties.

  - keypad,row: the row number to which the key is connected.

  - keypad,column: the column number to which the key is connected.

  - linux,code: the key-code to be reported when the key is pressed

    and released.

- pinctrl-0: Should specify pin control groups used for this controller.

- pinctrl-names: Should contain only one value - "default".

Optional Properties:

- wakeup-source: use any event on keypad as wakeup event.

		 (Legacy property supported: "linux,input-wakeup")

Optional Properties specific to linux:

- linux,keypad-no-autorepeat: do no enable autorepeat feature.

Example:

	keypad@100a0000 {

		compatible = "samsung,s5pv210-keypad";

		reg = <0x100A0000 0x100>;

		interrupts = <173>;

		samsung,keypad-num-rows = <2>;

		samsung,keypad-num-columns = <8>;

		linux,input-no-autorepeat;

		wakeup-source;

		pinctrl-names = "default";

		pinctrl-0 = <&keypad_rows &keypad_columns>;

		key_1 {

			keypad,row = <0>;

			keypad,column = <3>;

			linux,code = <2>;

		};

		key_2 {

			keypad,row = <0>;

			keypad,column = <4>;

			linux,code = <3>;

		};

		key_3 {

			keypad,row = <0>;

			keypad,column = <5>;

			linux,code = <4>;

		};
