+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 APE6)
+    - "renesas,irqc-r8a7790" (R-Car H2)
+    - "renesas,irqc-r8a7791" (R-Car M2-W)
+    - "renesas,irqc-r8a7792" (R-Car V2H)
+    - "renesas,irqc-r8a7793" (R-Car M2-N)
+    - "renesas,irqc-r8a7794" (R-Car E2)
+- #interrupt-cells: has to be <2>: an interrupt index and flags, as defined in
+  interrupts.txt in this directory
+- clocks: Must contain a reference to the functional clock.
+
+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>;
+		clocks = <&mstp4_clks R8A7790_CLK_IRQC>;
+	};
