13 To compile the driver as module, choose M here: the module will be
18 config USB_ROLES_INTEL_XHCI
19 tristate "Intel XHCI USB Role Switch"

23 lines between the xHCI host controller and the dwc3 gadget controller
24 found on various Intel SoCs.
26 To compile the driver as a module, choose M here: the module will
