  5           Say Y here if your system has a Dual Role Hi-Speed USB
  6           controller based on the DesignWare HSOTG IP Core.

  8           For host mode, if you choose to build the driver as dynamically
  9           linked modules, the core module will be called dwc2.ko, the PCI
 10           bus interface module (if you have a PCI bus system) will be
 11           called dwc2_pci.ko, and the platform interface module (for
 12           controllers directly connected to the CPU) will be called
 13           dwc2_platform.ko. For gadget mode, there will be a single
 14           module called dwc2_gadget.ko.
 15 
 16           NOTE: The s3c-hsotg driver is now renamed to dwc2_gadget. The
 17           host and gadget drivers are still currently separate drivers.
 18           There are plans to merge the dwc2_gadget driver with the dwc2
 19           host driver in the near future to create a dual-role driver.

 83           non-periodic transfers, but of course the debug logs will be
 84           incomplete. Note that this also disables some debug messages
 85           for which the transfer type cannot be deduced.
