  5           Say Y or M here if your system has a Dual Role HighSpeed
  6           USB controller based on the DesignWare HSOTG IP Core.

  8           If you choose to build this driver as dynamically linked
  9           modules, the core module will be called dwc2.ko, the
 10           PCI bus interface module (if you have a PCI bus system)
 11           will be called dwc2_pci.ko and the platform interface module
 12           (for controllers directly connected to the CPU) will be called
 13           dwc2_platform.ko.
 14 
 15           NOTE: This driver at present only implements the Host mode
 16           of the controller. The existing s3c-hsotg driver supports
 17           Peripheral mode, but only for the Samsung S3C platforms.
 18           There are plans to merge the s3c-hsotg driver with this
 19           driver in the near future to create a dual-role driver.

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