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>;
