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;

	};
