7 | Say Y here if your system has a Dual Role Hi-Speed USB |
8 | controller based on the DesignWare HSOTG IP Core. | |
9 | ||
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 | |
5ee80705 DN |
15 | dwc2_platform.ko. For all modes(host, gadget and dual-role), there |
16 | will be an additional module named dwc2.ko. | |
