I think this does not really fit into the power-supply tree.
I would expect this to go through Rafael's linux-pm tree.

Note: I moved all the power-supply code into drivers/power/supply/
in linux-next, among other things because of this patchset. To avoid
merge conflicts in drivers/power/Makefile and drivers/power/Kconfig
the tree pulling this patchset should also pull a (yet to be
created) immutable branch containing
https://git.kernel.org/cgit/linux/kernel/git/sre/linux-power-supply.git/commit/drivers/power?h=for-next&id=8c0984e5a75337df513047ec92a6c09d78e3e5cd
