-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>;
-};
