+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;
+ };
