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>;
+};
