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?

In any case, there are optional and required device tree properties,
the CAMSS supplies shall be split into multiple ones and become optional.

That's exactly the point of my first message in the discussion, so far
nothing has been added or changed.
