What if we work towards a generic constraint framework which models
thermals as a performance constraint.

Drivers can register to this constraint; platform code can then decide
to issue restrictions either to the CPU or other power-hungry
peripherals based on the platform conditions.

That also allows to model CPU frequency as a generic constraint but
via an actual consumer, say the thermal driver.

Cheers!
