-	   The most notable feature of USB OTG is support for a
-	   "Dual-Role" device, which can act as either a device
-	   or a host.  The initial role choice can be changed
-	   later, when two dual-role devices talk to each other.
-
-	   At this writing, the OTG support in this driver is incomplete,
-	   omitting the mandatory HNP or SRP protocols.  However, some
-	   of the cable based role switching works.  (That is, grounding
-	   the ID pin switches the controller to host mode, while leaving
-	   it floating leaves it in peripheral mode.)
-
-	   Select this if your system has a Mini-AB connector, or
-	   to simplify certain kinds of configuration.
-
-	   To implement your OTG Targeted Peripherals List (TPL), enable
-	   USB_OTG_WHITELIST and update "drivers/usb/core/otg_whitelist.h"
