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"

- phys: phandle to the USB PHY

Example:

usb_phy: usb-phy@0 {

	compatible = "usb-nop-xceiv";

	#phy-cells = <0>;

};

udc: usb@13040000 {

	compatible = "ingenic,jz4740-musb";

	reg = <0x13040000 0x10000>;

	interrupt-parent = <&intc>;

	interrupts = <24>;

	interrupt-names = "mc";

	clocks = <&cgu JZ4740_CLK_UDC>;

	clock-names = "udc";

	phys = <&usb_phy>;
