config USB_DWC2 tristate "DesignWare USB2 DRD Core Support" depends on USB depends on VIRT_TO_BUS help Say Y or M here if your system has a Dual Role HighSpeed USB controller based on the DesignWare HSOTG IP Core. If you choose to build this 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. NOTE: This driver at present only implements the Host mode of the controller. The existing s3c-hsotg driver supports Peripheral mode, but only for the Samsung S3C platforms. There are plans to merge the s3c-hsotg driver with this driver in the near future to create a dual-role driver. if USB_DWC2 config USB_DWC2_DEBUG bool "Enable Debugging Messages" help Say Y here to enable debugging messages in the DWC2 Driver. config USB_DWC2_VERBOSE bool "Enable Verbose Debugging Messages" depends on USB_DWC2_DEBUG help Say Y here to enable verbose debugging messages in the DWC2 Driver. WARNING: Enabling this will quickly fill your message log. If in doubt, say N. config USB_DWC2_TRACK_MISSED_SOFS bool "Enable Missed SOF Tracking" help Say Y here to enable logging of missed SOF events to the dmesg log. WARNING: This feature is still experimental. If in doubt, say N. config USB_DWC2_DEBUG_PERIODIC bool "Enable Debugging Messages For Periodic Transfers" 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. endif
