Device-Tree binding for ps/2 gpio device
|
|
|
|
Required properties:
|
|
- compatible = "ps2-gpio"
|
|
- data-gpios: the data pin
|
|
- clk-gpios: the clock pin
|
|
- interrupts: Should trigger on the falling edge of the clock line.
|
|
|
|
Optional properties:
|
|
- write-enable: Indicates whether write function is provided
|
|
to serio device. Possibly providing the write fn will not work, because
|
|
of the tough timing requirements.
|
|
|
|
Example nodes:
|
|
|
|
ps2@0 {
|
|
compatible = "ps2-gpio";
|
|
interrupt-parent = <&gpio>;
|
|
interrupts = <23 IRQ_TYPE_EDGE_FALLING>;
|
|
data-gpios = <&gpio 24 GPIO_ACTIVE_HIGH>;
|
|
clk-gpios = <&gpio 23 GPIO_ACTIVE_HIGH>;
|
|
write-enable;
|
|
};
