The glue driver handles platform specific requirements on the interaction between dwc3 and the USB2/USB3 PHY and reset-controller for USB role switches and plug events. To keep USB working as before when the nodes still carried "snps,dwc3" as compatible add "apple,t8103-dwc3" to the of match table. Eventually it is probably advisable to add a dwc3-apple glue driver and write code for the currently empty Apple Type-C PHY driver in phy-apple-atc.c.
