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 all modes(host, gadget and dual-role), there
|
||
|
|
will be an additional module named dwc2.ko.
