No, the supplies shall be optional, since it's absolutely possible to

such a board, where supplies are merely not connected to the SoC.
For any _used_ PHY both supplies are certainly required.
That's what the yaml/dts check for this should achieve.
I believe it is technically possible by writing an enormously complex
scheme, when all possible "port" cases and combinations are listed.
Do you see any simpler way? Do you insist that it is utterly needed?
I asked Krzysztof about this offline.
He said something like

This is possible, but I think not between child nodes.

You could require something in children, but not in parent node. For
children something around:
https://elixir.bootlin.com/linux/v6.4-rc7/source/Documentation/devicetree/bindings/net/qcom,ipa.yaml#L174
allOf:
- if:
required:
- something-in-parent
then:
properties:
child-node:
required:
- something-in-child
I will see if I can turn that into a workable proposal/patch.
