Thanks!

Indeed, dts updates should only go in through the platform maintainers
(i.e. through soc tree), unless there are strong reasons to bring them
in through driver trees.

If there's a need for a dt-include to be shared between driver and
dts, getting them on a stable branch that's merged through both trees
is usually the best way. Reach out when that happens and we can
coordinate.
