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 "SUSB_hdrc".

Dual-Role devices can support both host and peripheral roles,
as well as a the special "OTG Device" role which can switch
between both roles as needed.

# OTG needs both roles, not just USB_SUSB_HOST.

Say Y here if your system supports the USB host role.
If it has a USB "A" (rectangular), "Mini-A" (uncommon),
or "Mini-AB" connector, it supports the host role.
(With a "Mini-AB" connector, you should enable USB OTG.)

help
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.

This enables SUSB debugging. To set the logging level use the debug

packet, or dma transfer) tracing may kick in.
