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.

The most notable feature of USB OTG is support for a
|
|
|
|
"Dual-Role" device, which can act as either a device
|
|
|
|
or a host. The initial role choice can be changed
|
|
|
|
later, when two dual-role devices talk to each other.
|
|
|
|
|
|
|
|
At this writing, the OTG support in this driver is incomplete,
|
|
|
|
omitting the mandatory HNP or SRP protocols. However, some
|
|
|
|
of the cable based role switching works. (That is, grounding
|
|
|
|
the ID pin switches the controller to host mode, while leaving
|
|
|
|
it floating leaves it in peripheral mode.)
|
|
|
|
|
|
|
|
Select this if your system has a Mini-AB connector, or
|
|
|
|
to simplify certain kinds of configuration.
|
|
|
|

|
|
|
To implement your OTG Targeted Peripherals List (TPL), enable
|
|
|
|
USB_OTG_WHITELIST and update "drivers/usb/core/otg_whitelist.h"
|
|
|
|
to match your requirements.
