thermal: Introduce a debugfs-based testing facility Introduce a facility allowing the thermal core functionality to be exercised in a controlled way in order to verify its behavior, without affecting its regular users noticeably. It is based on the idea of preparing thermal zone templates along with their trip points by writing to files in debugfs. When ready, those templates can be used for registering test thermal zones with the thermal core. The temperature of a test thermal zone created this way can be adjusted via debugfs, which also triggers a __thermal_zone_device_update() call for it. By manipulating the temperature of a test thermal zone, one can check if the thermal core reacts to the changes of it as expected. Signed-off-by: Rafael J.
