This affects only rk3328 devices, but so far none of them has enabled the driver except roc-pc and station-m1; station-m1 dts file has been removed since it does not appear in CURRENT kernel patch directory, roc-pc device tree has been adapted. So far I tested the phy driver a bit going into the OTG journey. It turned out that does not work at all with the dwc3 USB3 core driver; The phy driver presence is somewhat necessary to attach the proper OTG vbus regulator for OTG function, thus removing the driver will probably hinder future OTG functionality; on the opposite side, enabling the phy driver in device tree breaks regular HOST functionality (the kernel does not see any USB3 device anymore...), so I guess it is probably better to remove it at all.
