  19           Say Y here if your system has a dual role high speed USB
  20           controller based on the Mentor Graphics silicon IP.  Then
  21           configure options to match your silicon and the board
  22           it's being used with, including the USB peripheral role,
  23           or the USB host role, or both.

 107            The most notable feature of USB OTG is support for a
 108            "Dual-Role" device, which can act as either a device
 109            or a host.  The initial role choice can be changed
 110            later, when two dual-role devices talk to each other.
 111
 112            At this writing, the OTG support in this driver is incomplete,
 113            omitting the mandatory HNP or SRP protocols.  However, some
 114            of the cable based role switching works.  (That is, grounding
 115            the ID pin switches the controller to host mode, while leaving
 116            it floating leaves it in peripheral mode.)
 117
 118            Select this if your system has a Mini-AB connector, or
 119            to simplify certain kinds of configuration.

 121            To implement your OTG Targeted Peripherals List (TPL), enable
