   1* OHCI controller, NXP ohci-nxp variant
   2
   3Required properties:
   4- compatible: must be "nxp,ohci-nxp"
   5- reg: physical base address of the controller and length of memory mapped
   6  region.
   7- interrupts: The OHCI interrupt
   8- transceiver: phandle of the associated ISP1301 device - this is necessary for
   9               the UDC controller for connecting to the USB physical layer
  10
  11Example (LPC32xx):
  12
  13        isp1301: usb-transceiver@2c {
  14                compatible = "nxp,isp1301";
  15                reg = <0x2c>;
  16        };
  17
  18        ohci@31020000 {
  19                compatible = "nxp,ohci-nxp";
  20                reg = <0x31020000 0x300>;
  21                interrupt-parent = <&mic>;
  22                interrupts = <0x3b 0>;
  23                transceiver = <&isp1301>;
  24        };
