-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;
-};
