Filename must match compatible and compatible has completely broken
format. Please look at DT spec or any other examples how compatibles are
created.

Useless description. You keep repeating the same.

Why the fallback?

Your commit msg is also useless here, you just wrote what you did, not why.

I see no reason why generic "bus" like that should stay generic,
although you have entire commit msg to explain why this is different or
what is the versioning of this IP block.

Missing blank line.

This follows properties.

Drop, irrelevant

Really, this is the style you send? So the toolset - dt-check-style - or
the Coding style mean nothing and you keep sending what you have in
downstream.
