Merge patch series "JH7110 PMU Support" 



Walker Chen <walker.chen@starfivetech.com> says:

Add the PMU (Power Management Unit) controller driver for the
StarFive JH7110 SoC. In order to meet low power requirements, PMU is
designed for including multiple PM domains that can be used for power
gating of selected IP blocks for power saving by reduced leakage
current.
