Correct.

Vybrid is one i use a lot with two FECs.

Exactly. This patch set itself adds nothing we don't already support.
So the patch set as is, is pointless.

I fully agree. All it needs for this patchset to be merged is another
patch which adds GPR properties to all SoC .dtsi files where
appropriate, and optionally to a couple of reference designs which
support WoL on their ports.
