[PATCH 3/4] arm64: dts: socfpga: agilex5: enable gmac2 on the Agilex5 dev kit

[Andrew Lunn]

Please could you explain in more details what this means.

The normal meaning for 'rgmii' is that the PCB implements the delay. I
just want to fully understand what this IO ring is, and if it is part
of the PCB.

Please add a newline in here to separate the inner node from the
rest.
