Make the mlxsw core_thermal driver use the .should_bind() thermal zone callback to provide the thermal core with the information on whether or not to bind the given cooling device to the given trip point in the given thermal zone. If it returns 'true', the thermal core will bind the cooling device to the trip and the corresponding unbinding will be taken care of automatically by the core on the removal of the involved thermal zone or cooling device. It replaces the .bind() and .unbind() thermal zone callbacks (in 3 places) which assumed the same trip points ordering in the driver and in the thermal core (that may not be true any more in the future). The .bind() callbacks used loops over trip point indices to call thermal_zone_bind_cooling_device() for the same cdev (once it had been verified) and all of the trip points, but they passed different 'upper' and 'lower' values to it for each trip. To retain the original functionality, the .should_bind() callbacks need to use the same 'upper' and 'lower' values that would be used by the corresponding .bind() callbacks when they are about to return 'true'. To that end, the 'priv' field of each trip is set during the thermal zone initialization to point to the corresponding 'state' object containing the maximum and minimum cooling states of the cooling device.

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 reStructuredText 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.
