There was an issue in how the tach feedbacks of dual rotor fans were reported during any change in fan speeds with revision "A" of the MAX31785. When the fan speeds would transition to a new target speed, the rotor not wired to the TACH input when TACHSEL = 0 would report a speed of 0 until the new target was reached. This has been fixed, resulting in a revision "B" update where the MFR_REVISION of "B" is 0x3061.

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.
