-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>;
-};
