You may find some information from sysfs.
For example, you can read sensors with:

for tz in `ls -d /sys/class/thermal/thermal_zone*`; do temp=`cat $tz/temp`; echo `cat $tz/type` ':' `expr $temp / 1000`; done

You’ll find that there are for each thermal zone some trip points:

for tz in `ls -d /sys/class/thermal/thermal_zone*`; do echo; cat $tz/type; for tp in `ls $tz/trip_point_*_temp`; do temp=`cat $tp`; echo $tp ' : ' `expr $temp / 1000`; done; done

and for PMIC-Die, the trip point is at 120°C. So as long as it shows 100°C [or maybe scareless value 50°C in R32.6), you know it is below 120°C.
