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.
