* step_wise_throttle - throttles devices associated with the given zone
* @tz - thermal_zone_device
- * @trip - the trip point
- * @trip_type - type of the trip point
+ * @trip - trip point index

* Throttling Logic: This uses the trend of the thermal zone to throttle.
* If the thermal zone is 'heating up' this throttles all the cooling
