7 Say Y here if your system has a Dual Role Hi-Speed USB
8 controller based on the DesignWare HSOTG IP Core.

10 For host mode, if you choose to build the driver as dynamically
11 linked modules, the core module will be called dwc2.ko, the PCI
12 bus interface module (if you have a PCI bus system) will be
13 called dwc2_pci.ko, and the platform interface module (for
14 controllers directly connected to the CPU) will be called

15 dwc2_platform.ko. For all modes(host, gadget and dual-role), there
16 will be an additional module named dwc2.ko.

51 the role will be determined by the cable that gets plugged-in. This
