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
