+Device-Tree bindings for GPIO attached mice
+
+This simply uses standard GPIO handles to define a simple mouse connected
+to 5-7 GPIO lines.
+
+Required properties:
+ - compatible: must be "gpio-mouse"
+ - scan-interval-ms: The scanning interval in milliseconds
+ - up-gpios: GPIO line phandle to the line indicating "up"
+ - down-gpios: GPIO line phandle to the line indicating "down"
+ - left-gpios: GPIO line phandle to the line indicating "left"
+ - right-gpios: GPIO line phandle to the line indicating "right"
+
+Optional properties:
+ - button-left-gpios: GPIO line handle to the left mouse button
+ - button-middle-gpios: GPIO line handle to the middle mouse button
+ - button-right-gpios: GPIO line handle to the right mouse button
+Example:
+
+#include <dt-bindings/gpio/gpio.h>
+
+gpio-mouse {
+ compatible = "gpio-mouse";
+ scan-interval-ms = <50>;
+ up-gpios = <&gpio0 0 GPIO_ACTIVE_LOW>;
+ down-gpios = <&gpio0 1 GPIO_ACTIVE_LOW>;
+ left-gpios = <&gpio0 2 GPIO_ACTIVE_LOW>;
+ right-gpios = <&gpio0 3 GPIO_ACTIVE_LOW>;
+ button-left-gpios = <&gpio0 4 GPIO_ACTIVE_LOW>;
+ button-middle-gpios = <&gpio0 5 GPIO_ACTIVE_LOW>;
+ button-right-gpios = <&gpio0 6 GPIO_ACTIVE_LOW>;
+};
