This patch was originally introduced when we made power_allocator the

Javi seems like this idea much.
While I can understand why this is not suitable for devicetree, we
should have a way in the kernel to configure different governors for
different thermal zones defined in device tree. Thermal zones defined
from platform code can choose the thermal governor when they are
registered.
If this information can't go in device tree, where can we put it? As
an additional parameter to thermal_zone_of_sensor_register()?
Why can't it be via sysfs allowing users to select their choice of
governor ? (like cpuidle/freq or even devfreq I assume)
