| |
| 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. |
