10	help
11	  Say Y here if your system has a dual role high speed USB
12	  controller based on the Mentor Graphics silicon IP.  Then
13	  configure options to match your silicon and the board
14	  it's being used with, including the USB peripheral role,
15	  or the USB host role, or both.
16
17	  Texas Instruments families using this IP include DaVinci
18	  (35x, 644x ...), OMAP 243x, OMAP 3, and TUSB 6010.
19
20	  Analog Devices parts using this IP include Blackfin BF54x,
21	  BF525 and BF527.
22
23	  If you do not know what this is, please say N.
24
25	  To compile this driver as a module, choose M here; the
26	  module will be called "musb-hdrc".
