After some testing on a Fujitsu Esprimo P720, it turned out that the limit registers are indeed writable and affect the fan control algorithm. This is supported by the datasheet, which says that the fan control functions are based on the limit and parameter registers. Since accessing those registers is very inefficient, the existing regmap cache is used to cache those registers values. Tested on a Fujitsu Esprimo P720.

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.
