The dwc2-pci driver requires the generic PHY. This fixes undefined reference issues when it is not selected. Reported-by: kbuild test robot <fengguang.wu@intel.com> Signed-off-by: John Youn <johnyoun@synopsys.com> Signed-off-by: Felipe Balbi <balbi@ti.com>

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.
