+Ingenic JZ4740 MUSB driver
+
+Required properties:
+
+- compatible: Must be "ingenic,jz4740-musb"
+- reg: Address range of the UDC register set
+- interrupts: IRQ number related to the UDC hardware
+- interrupt-names: must be "mc"
+- clocks: phandle to the "udc" clock
+- clock-names: must be "udc"
+
+Example:
+
+udc: usb@...40000 {
+	compatible = "ingenic,jz4740-musb";
+	reg = <0x13040000 0x10000>;
+
+	interrupt-parent = <&intc>;
+	interrupts = <24>;
+	interrupt-names = "mc";
+
+	clocks = <&cgu JZ4740_CLK_UDC>;
+	clock-names = "udc";
+};
