Since the 2019 a1k.org community re-print of these PCBs sports an LTC2990 hwmon chip as an example use case, let this driver autoprobe for that as well. If it is present, modprobing ltc2990 is sufficient. The property_entry enables the three additional inputs available on this particular board: in1 will be the voltage of the 5V rail, divided by 2. in2 will be the voltage of the 12V rail, divided by 4. temp3 will be measured using a PCB loop next the chip.

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.
