The builds were failing after I applied everything to respective
branches (so DTS separate). I did not notice that your DTS and driver
(both) depend on bindings header constant. This requires special
handling. It actually always required, because it was going through
different trees. Now it goes through my tree, but I still need to handle
it. I reworked the branches and force-pushed, thus you did not see the
exact issue.
