All of the passive trip points you added that aren't bound to any
cooling devices should be critical instead (otherwise they're not
doing anything)
otherwise, looks good

Don't we need cooling-maps for CPU thermal zones?

thanks for the review & comment, let me send 3rd patch with critical for
all trips.
