Hi Guys,
The cpu_cooling driver is designed to use CPU frequency scaling to avoid high thermal states for a platform. But it wasn't glued really well with cpufreq core. For example clipped-cpus is copied from the policy structure and its much better to use the policy->cpus (or related_cpus) fields directly as they may have got updated. Not that things were broken before this series, but they can be optimized a bit more.
This series tries to improve interactions between cpufreq core and cpu_cooling driver and does some fixes/cleanups to the cpu_cooling driver.
I have tested it on ARM 32 (exynos) and 64 bit (hikey) boards (haven't tested the power specific bits).
Lukasz from ARM has been very generous in testing and finding out few bugs in the earlier versions and getting those fixed. He has successfully tested the new version on his ARM big LITTLE Juno board.
Pushed here as well:

V3->V4:
Took this version into my -linus branch for the next merge window. Including the patch to remove the checkpatch warning. But please send an extra patch to fix the style pointed on patch 8.
