   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         };
