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>;

};
