* NXP LPC32xx SoC USB Device Controller (UDC)

Required properties:
- compatible: Must be "nxp,lpc3220-udc"
- reg: Physical base address of the controller and length of memory mapped
  region.
- interrupts: The USB interrupts:
              * USB Device Low Priority Interrupt
              * USB Device High Priority Interrupt
              * USB Device DMA Interrupt
              * External USB Transceiver Interrupt (OTG ATX)
- transceiver: phandle of the associated ISP1301 device - this is necessary for
               the UDC controller for connecting to the USB physical layer

Example:

	isp1301: usb-transceiver@2c {
		compatible = "nxp,isp1301";
		reg = <0x2c>;
	};

	usbd@31020000 {
		compatible = "nxp,lpc3220-udc";
		reg = <0x31020000 0x300>;
		interrupt-parent = <&mic>;
		interrupts = <0x3d 0>, <0x3e 0>, <0x3c 0>, <0x3a 0>;
		transceiver = <&isp1301>;
	};
