From: Dipa Ramesh Mantre <[email protected]> Unlike the CPU, the CDSP does not throttle its speed automatically when it reaches high temperatures in hamoa.
Set up CDSP cooling for both instances by throttling the cdsp, when it reaches 95°C. Add polling-delay-passive so the governor periodically evaluates the zone during passive cooling and steps up cooling levels when temperature stabilizes below the next trip.
