Give the opportunity to the drivers to create a thermal zone with thermal trips which will be accessible directly from the thermal core framework. As we added the thermal trip points structure in the thermal zone, let's extend the thermal zone register function to have the thermal trip structures as a parameter and store it in the 'trips' field of the thermal zone structure. The thermal zone contains the trip point, we can store them directly when registering the thermal zone. That will allow another step forward to remove the duplicate thermal zone structure we find in the thermal_of code.
