How this else is possible? Please show me any DTS which triggers this
else case.

Still nothing improved. Where is the fallback?

Don't write useless driver description and implement proper list of two
compatibles using one as fallback for another. I already pointed you to
example-schema which gives you nice example for this.

It is third try not doing what I asked you. Probably we misunderstand
each other, then please answer:

1. Please find example-schema.yaml and share whether this succeeded or not.
2. Open the example-schema.yaml in your editor.
3. Read the section about compatibles. You need oneOf and items, just
like it is there.

Now, please confirm that you did all these steps before you send v4 with
more test.

OK, you clearly just keep ignoring my comments.

This is a friendly reminder during the review process.

It seems my or other reviewer's previous comments were not fully
addressed. Maybe the feedback got lost between the quotes, maybe you
just forgot to apply it. Please go back to the previous discussion and
either implement all requested changes or keep discussing them.

Thank you.
