From: Nazim Amirul <redacted> The Agilex5 SoCDK TSN Config2 gmac1 path includes an FPGA soft-IP GMII-to-RGMII converter between the DWXGMAC and the PHY. The converter provides the RGMII TX/RX delays and presents GMII toward the MAC, unlike a plain altr,socfpga-stmmac-agilex5 port with no such converter. Add altr,socfpga-stmmac-agilex5-tsn for that integration. It is not listed as compatible with altr,socfpga-stmmac-agilex5 because the converter presents GMII to the MAC and supplies the RGMII delays, unlike a plain Agilex5 GMAC port.

So this should be part of enum of earlier list of altr,socfpga-stmmac-agilex5. Best regards, Krzysztof
