  19           controller based on the Mentor Graphics silicon IP.  Then
  20           configure options to match your silicon and the board
  21           it's being used with, including the USB peripheral role,
  22           or the USB host role, or both.

  66           The TUSB 6010 chip, from Texas Instruments, connects a discrete
  67           HDRC core using a 16-bit parallel bus (NOR flash style) or VLYNQ
  68           (a high speed serial link).  It can use system-specific external

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