i.MX8 MPlus SoC integrates Cadence HIFI4 DSP. This core runs either a custom firmware or the open source SOF firmware [1] DSP device is handled by SOF OF driver found in sound/soc/sof/sof-of-dev.c Notice that the DSP node makes use of: - dsp_reserved, a reserved memory region for various Audio resources (e.g firmware loading, audio buffers, etc). - Messaging Unit (mu2) for passing notifications betweem ARM core and DSP.

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.
