Trip points for your zones Thanks for the review. In some cases, the temperatures are just exposed so something in userspace might read it and do something with it. We don't expect kernel trips for them. Adding trip points also requires me to add cooling-maps (your point b. below). I guess I'm looking for an example of how to just expose sensor temperatures w/o any associated trips and cooling maps. > b. Cooling Mappings for zones that have passive trips. > From what I can see currently only CPUs and GPUs (among the major heat sources) can passively reduce heat by reducing frequencies. Things like cameras, display, video might have a more ON/OFF approach to throttling that might be controlled from userspace. And we don't have a way to tell in DT that these zones are managed in userspace (https://patchwork.kernel.org/patch/10259487/)
