These patches create 5 thermal zones, one for each sensor.  Due to the
way the exynos code in drivers/thermal/samsung/exynos_thermal_common.c
registers thermal zones, each one gets a cpufreq_cooling_device.
Therefore you end up with 5 thermal zone each of which is controlling
the cpu frequency.

Wouldn't it be better to collate these 5 sensors to create one thermal
zone for the whole SoC?  Maybe a simplistic algorithm like reporting
the maximum temperature of all the sensors as the thermal zone
temperature is good enough.

Cheers,
Javi
