Merge tag 'v4.4-rockchip-drivers1' of git://git.kernel.org/pub/scm/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.
* tag 'v4.4-rockchip-drivers1' of git://git.kernel.org/pub/scm/linux/kernel/git/mmind/linux-rockchip:
soc: rockchip: power-domain: Add power domain driver
dt-bindings: add document of Rockchip power domains
PM / clk: Do not __clk_get passed in clock-references
dt-bindings: add power-domain header for RK3288 SoCs
