When the voltage for OPPs is adjusted there is a need to also update
Energy Model framework. The EM data contains power values which depend
on voltage values. The EM structure is used for thermal (IPA governor)
and in scheduler task placement (EAS) so it should reflect the real HW
model as best as possible to operate properly.
Based on data on Exynos5422 ASV tables the maximum power difference might
be ~29%. An Odroid-XU4 (with a random sample SoC in this chip lottery)
showed power difference for some OPPs ~20%. Therefore, it's worth to
update the EM.

I assume there is dependency, even though cover letter did not mention
it, so:

Thanks Krzysztof for the review. Yes, it touches driver in your tree
indeed. Hopefully it can goes smoothly via Rafael's tree with your
tag.
