DT bindings for the R-Mobile/R-Car interrupt controller



Required properties:



- compatible: has to be "renesas,irqc-<soctype>", "renesas,irqc" as fallback.

  Examples with soctypes are:

    - "renesas,irqc-r8a73a4" (R-Mobile AP6)

    - "renesas,irqc-r8a7790" (R-Car H2)

    - "renesas,irqc-r8a7791" (R-Car M2)

- #interrupt-cells: has to be <2>: an interrupt index and flags, as defined in

  interrupts.txt in this directory



Optional properties:



- any properties, listed in interrupts.txt, and any standard resource allocation

  properties



Example:



	irqc0: interrupt-controller@e61c0000 {

		compatible = "renesas,irqc-r8a7790", "renesas,irqc";

		#interrupt-cells = <2>;

		interrupt-controller;

		reg = <0 0xe61c0000 0 0x200>;

		interrupts = <0 0 IRQ_TYPE_LEVEL_HIGH>,

			     <0 1 IRQ_TYPE_LEVEL_HIGH>,

			     <0 2 IRQ_TYPE_LEVEL_HIGH>,

			     <0 3 IRQ_TYPE_LEVEL_HIGH>;
