For the series:

I'm hoping that someone with knowledge of the power APIs will take a
look now that the driver looks to be in a pretty good state (to my naive
eyes at least).

FYI, please pick something more recent than that.
Ideally, the last -rc1, which in this case is v6.2-rc1.
It's helpful to do this, as when I went to apply your patch, there were
some conflicts that needed to be sorted out. Because of your prerequisite
patches, the usual `b4` commands would not usable. E.g.

b4 am -3 20230116074259.22874-1-walker.chen@...rfivetech.com

  ERROR: Could not find matching blob for MAINTAINERS (85e8f83161d7)
         If you know on which tree this patchset is based,
         add it as a remote and perform "git remote update"
         in order to fetch the missing objects.

Fortunately, this is just a driver addition so despite `b4` not
helping it was easy to resolve but for other patches in the future,
this may not be the case.

Assuming the dt maintainers are happy with the binding, ping me in 2
weeks if no-one else has commented and I'll apply patches 1 & 2.

Thanks,
Conor.
