Faraday Technology FTGPIO010 GPIO Controller

Required properties:

- compatible : Should be one of

  "cortina,gemini-gpio", "faraday,ftgpio010"

  "moxa,moxart-gpio", "faraday,ftgpio010"

  "faraday,ftgpio010"

- reg : Should contain registers location and length

- interrupts : Should contain the interrupt line for the GPIO block

- gpio-controller : marks this as a GPIO controller

- #gpio-cells : Should be 2, see gpio/gpio.txt

- interrupt-controller : marks this as an interrupt controller

- #interrupt-cells : a standard two-cell interrupt flag, see

  interrupt-controller/interrupts.txt

Example:

gpio@4d000000 {

	compatible = "cortina,gemini-gpio", "faraday,ftgpio010";

	reg = <0x4d000000 0x100>;

	interrupts = <22 IRQ_TYPE_LEVEL_HIGH>;

	gpio-controller;

	#gpio-cells = <2>;

	interrupt-controller;

	#interrupt-cells = <2>;
