  22           UTMI+ Low Pin Interface (ULPI) is specification for a commonly used
  23           USB 2.0 PHY interface. The ULPI specification defines a standard set
  24           of registers that can be used to detect the vendor and product which
  25           allows ULPI to be handled as a bus. This module is the driver for that
  26           bus.
  27
  28           The ULPI interfaces (the buses) are registered by the drivers for USB
  29           controllers which support ULPI register access and have ULPI PHY
  30           attached to them. The ULPI PHY drivers themselves are normal PHY
  31           drivers.
  32
  33           ULPI PHYs provide often functions such as ADP sensing/probing (OTG
  34           protocol) and USB charger detection.

  36           To compile this driver as a module, choose M here: the module will
  37           be called ulpi.

  45           The driver supports USB role switch between host and device via GPIO
  46           based USB cable detection, used typically if an input GPIO is used
  47           to detect USB ID pin, and another input GPIO may be also used to detect
  48           Vbus pin at the same time, it also can be used to enable/disable
  49           device if an input GPIO is only used to detect Vbus pin.
