Merge tag 'genpd-v6.5-rc1-1' of git://git.kernel.org/pub/scm/linux/kernel/git/ulfh/linux-pm into v6.6/drivers-genpd
Create the new genpd subsystem and start moving providers There are currently ~60 users of the genpd provider interface, which implementations are sprinkled across various subsystems. To help out with maintenance and to gain a bit better control, this creates a new subsystem (drivers/genpd) and moves some of the soc/platform specific providers in here.
