No, it does not solve it.
1. Patchset goes via separate trees (DTS are always separate), so it is
not bisectable. One of the branches/trees will have broken DTS.

2. All out of tree DTSes are broken. This is expressed as ABI and - with
some reasonable exceptions - you should not break it.

You have to keep backwards compatibility, so parse/handle both versions
of DTS.
