[PATCH RFC 0/8] Exynos850 CPU hotplug support and pmu_intr_gen cleanup

[Alexey Klimov]

This is RFC series in order to understand if it is the correct
direction in order of moving forward enabling support for CPU
hotplug on Exynos850-based platforms.
First steps are generalisations of similar routines and device
tree things for gs101 to make them more "Exynos" friendly and
last commits add actual support.

Tested on Exynos850 WinLink E850-96 board.

Some commits need to be squashed together probably but at this point
they allow to better understand the thinking process.
I was thinking to merge deprecation of google,pmu-intr-gen-syscon
into the previous commit and renaming of GS101_INTR_* registers
should not be a separate patch.

The {offline,online} calls should probably be moved into a 
SoC's DT match data since they look to be SoC-specific at this
point if we don't bump into any surprises here.
Please also advice if, for instance, gs101 calls should be moved
into gs101-pmu.c or exynos850 calls should go into separate file.
