847a1685fSDinh Nguyen	  For host mode, if you choose to build the driver as dynamically
947a1685fSDinh Nguyen	  linked modules, the core module will be called dwc2.ko, the PCI
1047a1685fSDinh Nguyen	  bus interface module (if you have a PCI bus system) will be
1147a1685fSDinh Nguyen	  called dwc2_pci.ko, and the platform interface module (for
1247a1685fSDinh Nguyen	  controllers directly connected to the CPU) will be called
1347a1685fSDinh Nguyen	  dwc2_platform.ko. For gadget mode, there will be a single
1447a1685fSDinh Nguyen	  module called dwc2_gadget.ko.

1647a1685fSDinh Nguyen	  NOTE: The s3c-hsotg driver is now renamed to dwc2_gadget. The
1747a1685fSDinh Nguyen	  host and gadget drivers are still currently separate drivers.
1847a1685fSDinh Nguyen	  There are plans to merge the dwc2_gadget driver with the dwc2
1947a1685fSDinh Nguyen	  host driver in the near future to create a dual-role driver.
