* Faraday Technologt FTINTC010 interrupt controller

This interrupt controller is a stock IP block from Faraday Technology found
in the Gemini SoCs and other designs.

Required properties:
- compatible: must be one of
  "faraday,ftintc010"
  "cortina,gemini-interrupt-controller" (deprecated)
- 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 = "faraday,ftintc010"
	reg = <0x48000000 0x1000>;
	interrupt-controller;
	#interrupt-cells = <2>;
};
