The Renesas RZ/G1[ME] (R8A7743/5) usbdmac engine is identical to the R-Car Gen2 family. This doesn't change the driver, so it does nothing by itself. But it does mean that checkpatch won't complain about a future patch that adds "renesas,r8a7743-usb-dmac" or "renesas,r8a7745-usb-dmac" to a DT, which helps ensure that shipped DTs use documented compatibility strings.
