+Device-Tree bindings for input/joystick/gpio_joy.c joystick driver
+
+This driver can be used for connecting i.e. C64 and Atari joysticks.
+
+Required properties:
+	- compatible    = "gpio-joy";
+
+	- left-gpio     : gpio connected to the "left" joystick signal
+	- right-gpio    : gpio connected to the "right" joystick signal
+	- up-gpio       : gpio connected to the "up" joystick signal
+	- down-gpio     : gpio connected to the "down" joystick signal
+	- button-gpio   : gpio connected to the "button" joystick signal
+		See OF device-tree gpio specification.
+
+Optional properties:
+	- debounce-interval-ms: debounce interval in milliseconds for connected pins
+		Default is 10 milliseconds
+
+Example node:
+
+joystick {
+	compatible = "gpio-joy";
+	left-gpio = <&gpio 24 GPIO_ACTIVE_LOW>;
+	right-gpio = <&gpio 10 GPIO_ACTIVE_LOW>;
+	up-gpio	= <&gpio 3 GPIO_ACTIVE_LOW>;
+	down-gpio = <&gpio 27 GPIO_ACTIVE_LOW>;
+	button-gpio = <&gpio 2 GPIO_ACTIVE_LOW>;
+};
