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. Signed-off-by: Wei Fang <wei.fang@nxp.com> --- v2: Remove "nxp,imx95-enetc" compatible string. v3: 1. Add restriction to "clcoks" and "clock-names" properties and rename the clock, also remove the items from these two properties. 2. Remove unnecessary items for "pci1131,e101" compatible string. --- .../devicetree/bindings/net/fsl,enetc.yaml | 22 ++++++++++++++++--- 1 file changed, 19 insertions(+), 3 deletions(-)
