The OMAP3530 I-temp can run the core at up to 90 degrees C, but we have
concerns in using the part in industrial environments (where process
loading is unpredictable) that the temp may rise past that point. I
understand external heat sinks can be used to help mitigate the problem
but not all applications can use such.
What I'd like to do is to use the core CONTROL_TEMP_SENSOR to monitor
core temperature and if it rises too high, throttle the OPP point to
slow it down enough to keep it cool - and restore the OPP point if it
cools down enough, using hysteresis to prevent oscillation of the OPP
point while operating near the extremes.
Does anyone have suggestions on how I can best implement such in the
latest kernel?
Thanks in advance!
