Nícolas F. R. A. Prado 2bba1acf7a thermal/drivers/mediatek/lvts_thermal: Manage threshold between sensors
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.

README

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
