Critical temperature on IMX8M Mini

When we did the imx8mm test, we encountered the system warning that the temperature was too high, reaching 95 degrees, I would like to ask why there was a warning at 95 degrees when we were using an industrial grade chip and the theoretical temperature should be able to reach 105 degrees.

Hi @DanielDuJijun 

The temperatures are read from TMU on SOC, you can modify them with thermal sysfs.

echo 105000 > /sys/class/thermal/thermal_zone0/trip_point_1_temp
