Yeah but those going through a different maintainer makes it more straightforward
to pick; besides, essentially, you can also get a full view with dt-bindings
patches instead of devicetrees, as the latter are "constructed from" bindings
anyway.

Moreover, it would be definitely nice to add a link to the devicetree series
in the cover letter of this series, so that people *do* get a full overview
by checking both series :-)

Cheers!
