Maybe it was not very clear, and I am working on improving this, but
what I am proposing is simply to have:
cooling-device = <&cdev min max>
where min and max are one cell unsigned values referring to minimum
cooling level and maximum cooling level, for this reference. Note that
'cdev' may have 10 levels, but in this reference we may use only from 6
to 10:
cooling-device = <&cdev 6 10>;
I don't see a need to have a cooling-names for this case. And for now, I
also don't see why we would use other specifiers. But we can leave it
open for future extensions.
It does make sense to have thermal-sensor-names (using thermal-sensor as
per your suggestion). Because it makes clear where the sensor is in the
case of using several sensors in one zone. Just like in the example I
already gave:

You have got to be excited about what you are doing. (L. Lamport)
