Changes in v5:
- List all supported compatible strings in the binding document.

Changes in v4:
  - s/intc/interrupt-controller/ in example.

Changes in v3:
- Merge documentation for various Ingenic SoCs, which only differ by
  their compatible strings.

Changes in v2: None

+Ingenic SoC Interrupt Controller
+
+Required properties:
+
+- compatible : should be "ingenic,<socname>-intc". Valid strings are:
+    ingenic,jz4740-intc
+    ingenic,jz4770-intc
+    ingenic,jz4775-intc
+    ingenic,jz4780-intc
+- reg : Specifies base physical address and size of the registers.
+- interrupt-controller : Identifies the node as an interrupt controller
+- #interrupt-cells : Specifies the number of cells needed to encode an
+  interrupt source. The value shall be 1.
+- interrupt-parent : phandle of the CPU interrupt controller.
+- interrupts : Specifies the CPU interrupt the controller is connected to.
+
+Example:
+
+intc: interrupt-controller@10001000 {
+	compatible = "ingenic,jz4740-intc";
+	reg = <0x10001000 0x14>;
+
+	interrupt-controller;
+	#interrupt-cells = <1>;
+
+	interrupt-parent = <&cpuintc>;
+	interrupts = <2>;
+};
