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.
