  24 +USB xHCI controllers
  25 +
  26 +Required properties:
  27 +  - compatible: should be "xhci-platform".
  28 +  - reg: should contain address and length of the standard XHCI
  29 +    register set for the device.
  30 +  - interrupts: one XHCI interrupt should be described here.
  31 +
  32 +Example:
  33 +       usb@f0931000 {
  34 +               compatible = "xhci-platform";
  35 +               reg = <0xf0931000 0x8c8>;
  36 +               interrupts = <0x0 0x4e 0x0>;
