The pci driver now registers a platform driver, like in dwc3, and lets its probe function do all the initialization. This allows it to account for changes to the platform driver that were not added to the pci driver. Also future changes to the probe function don't have to be duplicated. This also has the effect of adding device and DRD mode to the pci driver. Tested on the Synopsys HAPS PCIe platform.

Say Y here if your system has a Dual Role Hi-Speed USB
|
|
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.
