Missing vendor prefix documentation. I don't think you tested this at all with checkpatch and dt_binding_check.

Why there is no reference to ethernet-phy.yaml?

I don't think that's correct approach. You know affect all phys.

Just reference ethernet-phy.yaml.

Drop duplicated properties.

No underscores in node names. Missing vendor prefix. Both apply to all your other custom properties, unless they are not custom but generic.
Missing ref.

Nope, this is wrong. You wrote now boolean property as enum.

Nope. Use proper units and drop all this register stuff.

The binding is in very poor shape. Please look carefully in example-schema. All my previous comments apply everywhere.

This must be false. After referencing ethernet-phy this should be unevaluatedProperties: false.
