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

62 The TUSB 6010 chip, from Texas Instruments, connects a discrete
63 HDRC core using a 16-bit parallel bus (NOR flash style) or VLYNQ
64 (a high speed serial link). It can use system-specific external
65 DMA controllers.

104 The most notable feature of USB OTG is support for a
105 "Dual-Role" device, which can act as either a device
106 or a host. The initial role choice can be changed
107 later, when two dual-role devices talk to each other.
108
109 At this writing, the OTG support in this driver is incomplete,
110 omitting the mandatory HNP or SRP protocols. However, some
111 of the cable based role switching works. (That is, grounding
112 the ID pin switches the controller to host mode, while leaving
113 it floating leaves it in peripheral mode.)
114
115 Select this if your system has a Mini-AB connector, or
116 to simplify certain kinds of configuration.
117
118 To implement your OTG Targeted Peripherals List (TPL), enable
119 USB_OTG_WHITELIST and update "drivers/usb/core/otg_whitelist.h"
120 to match your requirements.
