1config USB_DWC2
2	bool "DesignWare USB2 DRD Core Support"
3	depends on USB || USB_GADGET
4	help
5	  Say Y here if your system has a Dual Role Hi-Speed USB
6	  controller based on the DesignWare HSOTG IP Core.
7
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.

81	  Say N here to disable (verbose) debugging messages to be
82	  logged for periodic transfers. This allows better debugging of
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.
