Hi Alexander,

Thank you for the patch.

In case the hardware only supports just one pipeline, allow using a
single port node as well.

This is frowned upon in DT bindings, as it makes them more complicated
for little gain. The recommendation is to always use a ports node if a
device can have multiple ports for at least one of its compatibles.

And reading the cover letter, I see this causes warnings. I think we
need guidance from Rob on this.

Here was similar case:
https://lore.kernel.org/all/20240227142440.GA3863852-robh@kernel.org/ (local)
and @Rob recommendation was to just use ports.

It's true it causes warnings... or I should say - it was causing
warnings (one of my last warnings in Samsung DTS for W=1).

I wonder what's the base of this patchset?
