The driver part has added the compatible string as you pointed out before.
Just sent a patch adding a compatible for it: https://lore.kernel.org/all/fec9df1a99ad8639f23edc24cdcc3ec78ea31575.1638881845.git.mchehab+huawei@kernel.org/T/#u (local) This is basically a DWC3 driver, using drivers/usb/dwc3/dwc3-of-simple.c to setup the needed clocks and reset pins to make DWC3 IP available.
