+ 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".
