Dinh Nguyen47a16852014-04-14 14:13:34 -070010 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
Dinh Nguyen5ee80702014-11-11 11:13:40 -060015 dwc2_platform.ko. For all modes(host, gadget and dual-role), there
16 will be an additional module named dwc2.ko.
