	  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 families using this IP include DaVinci
	  (35x, 644x ...), OMAP 243x, OMAP 3, and TUSB 6010.

	  Allwinner SoCs using this IP include A10, A13, A20, ...

	  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".
