I think the I/O board uses the FEC for its ethernet interface. It would
be nice to eventually move this to an I/O board overlay, but for now,

The regulator's datasheet shows a much smaller delay (about 1500µs with
a 3A load).

Is this really a property of the regulator ? Or a requirement of the
ethernet PHY ? In the latter case, shouldn't it be handled by the PHY ?

Why always on ? Same for the other supplies.

This seems to be produced by the SoM, it should be moved to the SoM
.dtsi.

Unless I'm mistaken, the PHYs are both at address 1. Address 0 works as
it's the broadcast address, but is there a good reason not to use the
real address ? Same below.

As written in the above comment: the delays are required by the PHYs.

I don't have the SoM schematics and I wanted to keep it simple while
porting the downstream DTS. For this regulator we can drop the
'regulator-alaways-on' property but for the others I rather tend to keep
it. As this is an EVK this board should never made it into real products
and so power-consumption/optimization isn't really important.

You're right, albeit the arrow is pointing to J6. I'll fix this.

Didn't verified the phy-addr since it was working after respecting the
power-delays. I will give it a try and assign the correct address.
