Device-Tree bindings for GPIO attached mice
2
-
3
-
This simply uses standard GPIO handles to define a simple mouse connected
4
-
to 5-7 GPIO lines.
5
-
6
-
Required properties:
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"
13
-
14
-
Optional properties:
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
18
-
Example:
19
-
20
-
#include <dt-bindings/gpio/gpio.h>
21
-
22
-
gpio-mouse {
23
-
compatible = "gpio-mouse";
24

-
down-gpios = <&gpio0 1 GPIO_ACTIVE_LOW>;
27
-
