+Ingenic SoCs Timer/Counter Unit Interrupt Controller
+
+Required properties:
+
+- compatible : should be "ingenic,<socname>-tcu-intc". Valid strings are:
+ * ingenic,jz4740-tcu-intc
+ * ingenic,jz4770-tcu-intc
+ * ingenic,jz4780-tcu-intc
+- 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 interrupt controller.
+- interrupts : Specifies the interrupt the controller is connected to.
+
+Example:
+
+/ {
+ mfd@10002000 {
+ compatible = "ingenic,tcu", "simple-mfd", "syscon";
+ reg = <0x10002000 0x1000>;
+
+ tcu_irq: interrupt-controller {
+ compatible = "ingenic,jz4740-tcu-intc";
+ reg = <0x10002020 0x20>;
+
+ interrupt-controller;
+ #interrupt-cells = <1>;
+
+ interrupt-parent = <&intc>;
+ interrupts = <15>;
+ };
+ };
+};
