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;
};
