+Cortina Systems Gemini GPIO Controller
+
+Required properties:
+
+- compatible : Must be "cortina,gemini-gpio"
+- 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";
+ reg = <0x4d000000 0x100>;
+ interrupts = <22 IRQ_TYPE_LEVEL_HIGH>;
+ gpio-controller;
+ #gpio-cells = <2>;
+ interrupt-controller;
+ #interrupt-cells = <2>;
+};
