Given the discussion, I'd marked this one as "changes requested"
expecting a new version to review the schema. And gmail decided to
make a new thread due to the extra 'RE:'. So it fell off my radar.

This schema is fundamentally broken as there's no way to match for
when to apply this schema. How do we find a NXP TJA11xx PHY? I suppose
we can look for 'ethernet-phy' with a child node 'ethernet-phy', but
then that would apply to any phy like this one. This needs a
compatible string IMO given it is non-standard.

Perhaps some information about how this phy is special.

Not needed here as ethernet-phy.yaml already has a 'select' condition to apply.

These aren't documented.
