+Device-Tree bindings for input/gpio_keys.c keyboard driver
+
+Required properties:
+	- compatible = "gpio-keys";
+
+Optional properties:
+	- autorepeat: Boolean, Enable auto repeat feature of Linux input
+	  subsystem.
+
+Each button (key) is represented as a sub-node of "gpio-keys":
+Subnode properties:
+
+	- reg: GPIO number the key is bound to if linux GPIO numbering is used.
+	- gpios: OF devcie-tree gpio specification, can be used alternatively
+	  if 'reg' is not specified, to use device-tree GPIOs.
+	- label: Descriptive name of the key.
+	- linux,code: Keycode to emit.
+
+Optional subnode-properties:
+	- active-low: Boolean flag to specify active-low GPIO input. Not used
+	  if device-tree gpios property is used.
+	- linux,input-type: Specify event type this button/key generates.
+	  Default if unspecified is <1> == EV_KEY.
+	- debounce-interval: Debouncing interval time in milliseconds.
+	  Default if unspecified is 5.
+	- wakeup: Boolean, button can wake-up the system.
+
+Example nodes:
+
+	gpio_keys {
+			compatible = "gpio-keys";
+			#address-cells = <1>;
+			#size-cells = <0>;
+			autorepeat;
+			button@20 {
+				label = "GPIO Key ESC";
+				linux,code = <1>;
+				reg = <0x20>;
+				key-active-low;
+				linux,input-type = <1>;
+			};
+			button@21 {
+				label = "GPIO Key UP";
+				linux,code = <103>;
+				gpios = <&gpio1 0 1>;
+				linux,input-type = <1>;
+			};
+			...
