Changelog
v1 -> v2
- Drop autorepeat property.
- Use unevaluatedProperties instead of additionalProperties.
- Use node name "touch@51" instead of "atmel-captouch@51".

-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;
-	};
