Sorry I should have included that. I added a print to dump this on another build but failed to include here.
WARNING KERN Generic PHY stmmac-0:00: supplier 2200000.gpio (status 1)
The status is the link->status and looks like the supplier is the gpio controller. I have verified that the gpio controller is probed before this successfully.

Correct, the board seems to boot fine, we just get this warning.
