1 Device-Tree bindings for GPIO attached mice
3 This simply uses standard GPIO handles to define a simple mouse connected
7 - compatible: must be "gpio-mouse"
8 - scan-interval-ms: The scanning interval in milliseconds
9 - up-gpios: GPIO line phandle to the line indicating "up"
10 - down-gpios: GPIO line phandle to the line indicating "down"
11 - left-gpios: GPIO line phandle to the line indicating "left"
12 - right-gpios: GPIO line phandle to the line indicating "right"
15 - button-left-gpios: GPIO line handle to the left mouse button
16 - button-middle-gpios: GPIO line handle to the middle mouse button
17 - button-right-gpios: GPIO line handle to the right mouse button
