+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>;
+};
