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. if USB_DWC2 config USB_DWC2_HOST tristate "Host only mode" depends on USB help The Designware USB2.0 high-speed host controller integrated into many SoCs. config USB_DWC2_PLATFORM bool "DWC2 Platform" depends on USB_DWC2_HOST default USB_DWC2_HOST help The Designware USB2.0 platform interface module for controllers directly connected to the CPU.

WARNING: This feature is still experimental.

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
