help
Say Y here if your system has a Dual Role Hi-Speed USB
controller based on the DesignWare HSOTG IP Core.
If you choose to build the driver as dynamically
linked modules, a single dwc2.ko(regardless of mode of operation)
will get built for both platform IPs and PCI.

The Designware USB2.0 high-speed host controller
integrated into many SoCs. Select this option if you want the
driver to operate in Host-only mode.

The Designware USB2.0 PCI interface module for controllers
connected to a PCI bus. This is only used for host mode.

help
The Designware USB2.0 high-speed gadget controller
integrated into many SoCs. Select this option if you want the
driver to operate in Peripheral-only mode. This option requires
USB_GADGET=y.

help
Select this option if you want the driver to work in a dual-role
mode. In this mode both host and gadget features are enabled, and
the role will be determined by the cable that gets plugged-in. This
option requires USB_GADGET=y.

help
Say N here to disable (verbose) debugging messages to be
logged for periodic transfers. This allows better debugging of
non-periodic transfers, but of course the debug logs will be
incomplete. Note that this also disables some debug messages
for which the transfer type cannot be deduced.
