Why? What part of hardware or real system use case is being solved here?

That's not a proper tag. See submitting patches.

Please use subject prefixes matching the subsystem. You can get them for
example with `git log --oneline -- DIRECTORY_OR_FILE` on the directory
your patch is touching. For bindings, the preferred subjects are
explained here:
https://www.kernel.org/doc/html/latest/devicetree/bindings/submitting-patches.html#i-for-patch-submitters

I don't understand what is happening with your patchset. It is being
changed in unexpected way, like something previously correct - like
subject - now is changed for some unexplained reason.

I don't understand what is "virtualcolor"

Do not need '|' unless you need to preserve formatting.

This sentence makes no sense. You describe here hardware in full
sentence. How hardware can "validates"?
