1Device-Tree binding for ps/2 gpio device
2
3Required properties:
4 - compatible = "ps2-gpio"
5 - data-gpios: the data pin
6 - clk-gpios: the clock pin
7 - interrupts: Should trigger on the falling edge of the clock line.
8
9Optional properties:
10 - write-enable: Indicates whether write function is provided
11 to serio device. Possibly providing the write fn will not work, because
12 of the tough timing requirements.

14Example nodes:
15
16ps2@0 {
17 compatible = "ps2-gpio";
18 interrupt-parent = <&gpio>;
19 interrupts = <23 IRQ_TYPE_EDGE_FALLING>;
20 data-gpios = <&gpio 24 GPIO_ACTIVE_HIGH>;
21 clk-gpios = <&gpio 23 GPIO_ACTIVE_HIGH>;
22 write-enable;
23};
