It is quite weird for PCIe devices. Device ID, at least Reversion ID should change. At least, I have not see use "nxp,imx95-enetc" at driver code.

The ENETC of i.MX95 has been upgraded to revision 4.1, and the vendor ID and device ID have also changed, so add the new compatible strings for i.MX95 ENETC. In addition, i.MX95 supports configuration of RGMII or RMII reference clock.
