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

+	  Texas Instruments familiies using this IP include DaVinci
+	  (35x, 644x ...), OMAP 243x, OMAP 3, and TUSB 6010.
+
+	  Analog Devices parts using this IP include Blackfin BF54x,
+	  BF525 and BF527.
+
+	  If you do not know what this is, please say N.
+
+	  To compile this driver as a module, choose M here; the
+	  module will be called "musb-hdrc".

+	help
+	   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"
+	   to match your requirements.
