| |
The governor of all thermal zones can be initialized in thermal_zone_device_register_with_trips(), but it is always the def_governor, this means the governor of all thermal zones are the same.
Allow users to set governor for a specific thermal zone in DT, in this way, users can use different policies for thermal management.
