   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 all modes(host, gadget and dual-role), there
  14          will be an additional module named dwc2.ko.

  49          the role will be determined by the cable that gets plugged-in. This

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