+ controller based on the DesignWare HSOTG IP Core.
+
+ 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.
