Merge tag 'v4.4-rockchip-drivers1' of git://git./linux/kernel/git/mmind/linux-rockchip into next/drivers

Merge "Rockchip power-domain drivers for 4.4" from Heiko Stuebner:

Add the power-domain base-driver which currently contains
support for the rk3288 powerdomain layout but can be easily
extended for the socs (including arm64) later on.
A big thanks to Ceasar Wang for pulling through on this
during 18 revisions.
Also included is a fix to the pm-clock handling in the generic
powerdomains to adapt it to the per-user clock handling we now
do, Acked by Rafael Wysocki.
