How to modify temperature initiated CPU scaling in Android (change temperature at which the CPU is scaled down)

[jant90]

The default ROM settings on my Amlogic S805 device suck (e.g. CPU governor set to hotplug). So I made some adjustments via a shell startup script and by using Kernel Adiutor. Shell startup script for those interested:

echo interactive > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
echo 1536000 > /sys/devices/system/cpu/cpufreq/interactive/hispeed_freq # Not sure if this line is necessary though
echo 1536000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq

However for a while I couldn't figure out for the life of me why the max CPU frequency was scaled down to 1.25GHz despite my shell script setting it to 1.536GHz. After some monitoring I think this happens when the CPU reaches a temperature of 70 degrees Celcius. So how can I change (in Android) at what temperature the CPU is scaled down? I would like to change it to 80 or 85 degrees or something so my device can run for a longer period time at max speed.

I hope this is possible from within Android somehow.
