I think we don't really want '+' (or '_') in compatible strings. That
would really a check against the documentation versus whether the dts
matches the documentation. So I probably should add a separate check
on use of documented, but deprecated compatible strings. Ideally, that
check would be on the binding doc, but since they are unstructured
currently, we'd have to do it on dts files.

Yes, indeed.
