Add the base device tree nodes for gmac0, gmac1, and gmac2 to the DTSI
for the Agilex5 SOCFPGA.  Agilex5 has three Ethernet controllers based on
Synopsys DWC XGMAC IP version 2.10.

Is there any feedback for this patch and the next one in the series,
"[PATCH v2 3/4] arm64: dts: socfpga: agilex5: enable gmac2 on the
Agilex5 dev kit"?

Thanks,

Just checking in again. Is there any feedback on this patch (v2 2/4) or 
the next patch (v2 3/4)?
