my comments from v1 apply here

None of the reasons you said force you to define properties in some
allOf:if:then subblock. These force you to constrain the properties in
allOf:if:then, but not define.

Of course you can and original bindings were doing it.

Let me ask specific questions (yes, no):
1. Are ethernet-ports and ethernet-port present in each variant?
2. Is dsa-port.yaml applicable to each variant? (looks like that - three
compatibles, three all:if:then)
3. If reg appearing in each variant?
4. If above is true, if reg is maximum one item in each variant?

Looking at your patch, I think answer is 4x yes, which means you can
define them in one place and constrain in allOf:if:then, just like all
other schemas, because this one is not different.

Best regards,
Krzysztof
