+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>;
+ };
