When separate branches get merged on Linus tree, it works anyway.

To avoid potential merge conflicts.  Unless there are hard dependencies
like making it compile, avoiding regression or maintaining bisect,
patches should go through their established subsystem/architecture tree.

Luckily.  If there are many patches on architecture DT branch changing
the same file, when driver branch and DT branch merges in upstream
branch, there will likely be merge conflicts.
