6 | Say Y here if your system has a Dual Role Hi-Speed USB |
7 | controller based on the DesignWare HSOTG IP Core. | |
8 | ||
9 | For host mode, if you choose to build the driver as dynamically | |
10 | linked modules, the core module will be called dwc2.ko, the PCI | |
11 | bus interface module (if you have a PCI bus system) will be | |
12 | called dwc2_pci.ko, and the platform interface module (for | |
13 | controllers directly connected to the CPU) will be called | |
5ee80705 DN |
14 | dwc2_platform.ko. For all modes(host, gadget and dual-role), there |
15 | will be an additional module named dwc2.ko. | |

48 | Select this option if you want the driver to work in a dual-role |

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