  vbus-detect-gpio:
    description: Should specify the GPIO detecting a VBus insertion
    maxItems: 1

  vbus-supply:
    description: regulator supplying VBUS. It will be enabled and disabled
                 dynamically in OTG mode. If the regulator is controlled by a
                 GPIO line, this should be modeled as a regulator-fixed and
                 referenced by this supply.

  wakeup-source:
    description:
      Specify if the USB phy can detect the remote wakeup signal
      while the system sleep.
