+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:
+
+ - gpios: OF devcie-tree gpio specificatin.
+ - label: Descriptive name of the key.
+ - linux,code: Keycode to emit.
+
+Optional subnode-properties:
+ - linux,input-type: Specify event type this button/key generates.
+ If not specified defaults to <1> == EV_KEY.
+ - debounce-interval: Debouncing interval time in milliseconds.
+ If not specified defaults to 5.
+ - gpio-key,wakeup: Boolean, button can wake-up the system.
+
+Example nodes:
+
+ gpio_keys {
+ compatible = "gpio-keys";
+ #address-cells = <1>;
+ #size-cells = <0>;
+ autorepeat;
+ button@21 {
+ label = "GPIO Key UP";
+ linux,code = <103>;
