Tested the series on a Exynos5420 based Peach Pit Chromebook by doing the
following for CPU0-3:
1) Verified that the big.LITTLE CPUFreq (arm-big-little) driver was reported as
used in /sys/devices/system/cpu/cpu*/cpufreq/scaling_driver.
2) Set all available governors (conservative, ondemand, userspace, powersave and
performance).
3) Confirmed that cpuinfo_cur_freq and scaling_cur_freq values were fixed or
changing according to the selected governor policy.
4) Verified that the statistics in /sys/devices/system/cpu/cpu*/cpufreq/stats/*
were filled.
Everything is working correctly so please feel free to add for the whole series:

Best regards,
Javier
