Suggestion was from Krzysztof to add platform specific comaptible (and
therefore schema). Since the first platform that will support in
upstream proper multi bus is the x1e80100, the schema needs to bear the
same name as the compatible. When support for multi bus will be added to
the other platforms (including the SM8450), they will use the fallback
compatible of the x1e80100 and will be documented in this newly added
schema. We did the same thing with some PHYs drivers, IIRC.

I can re-send the patchset with such a phrase in commit message.

One of the early versions of this patchset was actually submitting a
generic compatible for multi bus, but I remember that there was a
request for following the platform dedicated approach.

Krzysztof, can you please provide here the argument for why that is
preferred?
