I don't see the devicetree binding maintainers listed in the recipient
list, so adding them in the next iteration might increase your chances
to get an Ack on the binding.

scripts/get_maintainer.pl -f Documentation/devicetree/bindings lists

Rob Herring <robh+dt@...nel.org>
Mark Rutland <mark.rutland@....com>

as the main dt maintainers.

Is this common for all rk8xx pmics or just the two new ones?
As the paragraph above makes it sound like these are present on all
and I didn't find mention of them in the datasheets for previous pmics
I have.

Also to me it is not clear in what way these should be used and I didn't
find any mention of them at all in the rest of your series.
