Merge tag 'genpd-v6.6' of git://git.kernel.org/pub/scm/linux/kernel/git/ulfh/linux-pm
Pull ARM SoC generic power domain driver updates from Ulf Hansson:
"This adds a new subsystem for generic power domain providers in
drivers/genpd and starts moving some of the corresponding code in
there.
We have currently ~60 users of the genpd provider interface, which are
sprinkled across various subsystems. To release some burden from the
soc maintainers (Arnd Bergmann, etc) in particular, but also to gain a
better overall view of what goes on in the area, I will help out with
maintenance"
[ I find the "genpd" name singularly uninformative, so we'll probably
end up moving this driver subsystem somewhere else, but that's still
being discussed - Linus ]
