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. 20 21if USB_DWC2 22 23config USB_DWC2_HOST 24 tristate "Host only mode" 25 depends on USB 26 help 27 The Designware USB2.0 high-speed host controller 28 integrated into many SoCs. 29 30config USB_DWC2_PLATFORM 31 bool "DWC2 Platform" 32 depends on USB_DWC2_HOST 33 default USB_DWC2_HOST 34 help 35 The Designware USB2.0 platform interface module for 36 controllers directly connected to the CPU.
