Each LVTS thermal controller can have up to four sensors, each capable of triggering its own interrupt when its measured temperature crosses the configured threshold. The threshold for each sensor is handled separately by the thermal framework, since each one is registered with its own thermal zone and trips. However, the temperature thresholds are configured on the controller, and therefore are shared between all sensors on that controller. When the temperature measured by the sensors is different enough to cause the thermal framework to configure different thresholds for each one, interrupts start triggering on sensors outside the last threshold configured. To address the issue, track the thresholds required by each sensor and only actually set the highest one in the hardware, and disable interrupts for all sensors outside the current configured range.
