The current example for a thermal zone isn't very useful as reference since it would result in a hardware shutdown at 145°C, instead of allowing the system to try to shutdown gracefully. Without an ADC channel a maximum of two trip points is useful in practice for this sensor, with temperatures corresponding to the stage 1 and stage 2 'hardware trip points'. A critical trip point at stage 2 may allow the system to shutdown before a hardware shutdown at stage 3 kicks in. It should be noted though that by default the chip performs a 'partial shutdown' when the temperature reaches stage 2, which may prevent an orderly shutdown. The 'partial shutdown' can be disabled by software.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
