You are introducing new concept here, the original framework and drivers 
cannot use this, right? any further plan to update original framework 
for this new feature?

These macros seem duplicated with enum thermal_trip_type in thermal.h, 
do you have further plan to merge them?
Or by using string "active",  "passive" etc in the dts, then you can 
reuse the original enum definition.
