Add overlay to support PWM fan on the phyBOARD-Nash-i.MX93 board. Fan can be connected to the FAN (X48) connector on the board and will be controlled according to the following CPU temperature trips table: - bellow 50 degrees - fan is off (<1% duty cycle) - between 50 and 58 degrees - low fan speed (~35% duty cycle) - between 58 and 65 degrees - fan medium speed (~60% duty cycle) - above 65 degrees - fan at full speed (>99% duty cycle) The output frequency of PWM signal is set to 25 kHz.

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 reStructuredText 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.
