+DT bindings for the R-/SH-Mobile INTC controller
+
+Required properties:
+
+- compatible: Must be one of the following:
+    "renesas,intc"
+    "renesas,intc-r8a73a4"
+    "renesas,intc-r8a7790"
+    "renesas,intc-r8a7791"
+- #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 at e61c0000 {
+                compatible = "renesas,irqc-r8a7790", "renesas,irqc";
+                #interrupt-cells = <2>;
+                interrupt-controller;
+                reg = <0 0xe61c0000 0 0x200>;
+                interrupt-parent = <&gic>;
+                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>;
