[PATCH 5/5] thermal/drivers/intel: Use generic trip points for processor_thermal_device_pci

From: Daniel Lezcano
Date: Mon Dec 12 2022 - 15:59:27 EST


From: Daniel Lezcano <daniel.lezcano@xxxxxxxxxx>

The thermal framework gives the possibility to register the trip
points with the thermal zone. When that is done, no get_trip_* ops are
needed and they can be removed.

Convert ops content logic into generic trip points and register them with the
thermal zone.
