2	tristate "DesignWare USB2 DRD Core Support"
3	depends on USB
4	help
5	  Say Y or M here if your system has a Dual Role HighSpeed
6	  USB controller based on the DesignWare HSOTG IP Core.
7
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.

32	  Say Y here to enable verbose debugging messages in the DWC2 Driver.
33	  WARNING: Enabling this will quickly fill your message log.
34	  If in doubt, say N.

36config USB_DWC2_TRACK_MISSED_SOFS
37	bool "Enable Missed SOF Tracking"
38	help
39	  Say Y here to enable logging of missed SOF events to the dmesg log.
40	  WARNING: This feature is still experimental.

44	bool "Enable Debugging Messages For Periodic Transfers"
45	depends on USB_DWC2_DEBUG || USB_DWC2_VERBOSE
46	default y
47	help
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.
