8 For host mode, if you choose to build the driver as dynamically
9 linked modules, the core module will be called dwc2.ko, the PCI
10 bus interface module (if you have a PCI bus system) will be
11 called dwc2_pci.ko, and the platform interface module (for
12 controllers directly connected to the CPU) will be called
13 dwc2_platform.ko. For all modes(host, gadget and dual-role), there
14 will be an additional module named dwc2.ko.
