* Cortina Systems Gemini interrupt controller

This interrupt controller is found on the Gemini SoCs.

Required properties:
- compatible: must be "cortina,gemini-interrupt-controller"
- reg: The register bank for the interrupt controller.
- interrupt-controller: Identifies the node as an interrupt controller
- #interrupt-cells: The number of cells to define the interrupts.
  Must be 2 as the controller can specify level or rising edge
  IRQs. The bindings follows the standard binding for controllers
  with two cells specified in
  interrupt-controller/interrupts.txt

Example:

interrupt-controller@48000000 {
	compatible = "cortina,gemini-interrupt-controller";
	reg = <0x48000000 0x1000>;
	interrupt-controller;
	#interrupt-cells = <2>;
};
