config USB_DWC2
	bool "DesignWare USB2 DRD Core Support"
	depends on USB
	help
	  Say Y here if your system has a Dual Role Hi-Speed USB
	  controller based on the DesignWare HSOTG IP Core.

	  For host mode, if you choose to build the driver as dynamically
	  linked modules, the core module will be called dwc2.ko, the PCI
	  bus interface module (if you have a PCI bus system) will be
	  called dwc2_pci.ko, and the platform interface module (for
	  controllers directly connected to the CPU) will be called
	  dwc2_platform.ko. For gadget mode, there will be a single
	  module called dwc2_gadget.ko.

	  NOTE: The s3c-hsotg driver is now renamed to dwc2_gadget. The
	  host and gadget drivers are still currently separate drivers.
	  There are plans to merge the dwc2_gadget driver with the dwc2
	  host driver in the near future to create a dual-role driver.

config USB_DWC2_TRACK_MISSED_SOFS

	depends on USB_DWC2_DEBUG || USB_DWC2_VERBOSE
	default 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.
