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. 13 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}; 24
