Linus Walleij b786a05f6c ARM: dts: ux500: Update thermal zone ... After moving the DB8500 thermal driver to use device tree we define the default thermal zone for the Ux500 in the device tree replacing the oldstyle hardcoded trigger points. This default thermal zone utilizes the cpufreq driver (using the generic OF cpufreq back-end) as a passive cooling device, and defines a critical trip point when the temperature goes above 85 degrees celsius which will (hopefully) make the system shut down if the temperature cannot be controlled. This default policy can later be augmented for specific subdevices if these have tighter temperature conditions. After this patch we get: /sys/class/thermal/thermal_zone0 (CPU thermal zone) This reports the rough temperature and trip points from the thermal zone in the device tree. By executing two yes > /dev/null & jobs fully utilizing the two CPU cores we can notice the temperature climbing in the thermal zone in response and falling when we kill the jobs. /syc/class/thermal/cooling_device0 (cpufreq cooling) this reports all 4 available cpufreq frequencies as states.
