1Faraday Technology FTGPIO010 GPIO Controller
2
3Required properties:
4
5- compatible : Should be one of
6 "cortina,gemini-gpio", "faraday,ftgpio010"
7 "moxa,moxart-gpio", "faraday,ftgpio010"
8 "faraday,ftgpio010"
9- reg : Should contain registers location and length
10- interrupts : Should contain the interrupt line for the GPIO block
11- gpio-controller : marks this as a GPIO controller
12- #gpio-cells : Should be 2, see gpio/gpio.txt
13- interrupt-controller : marks this as an interrupt controller
14- #interrupt-cells : a standard two-cell interrupt flag, see
15 interrupt-controller/interrupts.txt

17Example:
18
19gpio@4d000000 {
20 compatible = "cortina,gemini-gpio", "faraday,ftgpio010";
21 reg = <0x4d000000 0x100>;
22 interrupts = <22 IRQ_TYPE_LEVEL_HIGH>;
23 gpio-controller;
24 #gpio-cells = <2>;
25 interrupt-controller;
26 #interrupt-cells = <2>;
27};
