This functionality is intended to allow for a few temperature sensors to be missing (and hence not worth reading) on the final device in a chain. The ones removed are 3 and 5 (unlike for the ADC channels where it is 4 and 5). The datasheet includes a foot note 3 to Table 12 that makes this complex to support. "(3) To remove AUX5 or AUX5 and AUX3 from the alert detection, conversions on three auxiliary ADC input channels only must be selected in the control register." This mode has never been supported by the driver. As this support would be complex to add and the rework is being done against a QEMU model developed for the purposes of verifying nothing is broken, it is better to drop this support for now.

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.
