Make the thermal_of 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. This replaces the .bind() and .unbind() thermal zone callbacks 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() callback would walk the given thermal zone's cooling maps to find all of the valid trip point combinations with the given cooling device and it would call thermal_zone_bind_cooling_device() for all of them using trip point indices reflecting the ordering of the trips in the DT. The .should_bind() callback still walks the thermal zone's cooling maps, but it can use the trip object passed to it by the thermal core to find the trip in question in the first place and then it uses the corresponding 'cooling-device' entries to look up the given cooling device. To be able to match the trip object provided by the thermal core to a specific device node, the driver sets the 'priv' field of each trip to the corresponding device node pointer during initialization.

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.
