    1 * NXP LPC32xx SoC USB Device Controller (UDC)
    2 
    3 Required properties:
    4 - compatible: Must be "nxp,lpc3220-udc"
    5 - reg: Physical base address of the controller and length of memory mapped
    6   region.
    7 - interrupts: The USB interrupts:
    8               * USB Device Low Priority Interrupt
    9               * USB Device High Priority Interrupt
   10               * USB Device DMA Interrupt
   11               * External USB Transceiver Interrupt (OTG ATX)
   12 - transceiver: phandle of the associated ISP1301 device - this is necessary for
   13                the UDC controller for connecting to the USB physical layer
   14 
   15 Example:
   16 
   17         isp1301: usb-transceiver@2c {
   18                 compatible = "nxp,isp1301";
   19                 reg = <0x2c>;
   20         };
   21 
   22         usbd@31020000 {
   23                 compatible = "nxp,lpc3220-udc";
   24                 reg = <0x31020000 0x300>;
   25                 interrupt-parent = <&mic>;
   26                 interrupts = <0x3d 0>, <0x3e 0>, <0x3c 0>, <0x3a 0>;
   27                 transceiver = <&isp1301>;
   28         };
