This adds sound support to the Reform2. It differs from the downstream implementation in that the codec is used as the BCLK and FSYNC master and the i.MX8MQ only supplies a fixed 25MHz MCLK from the oscillator. This allows to support a wider range of audio rates by using the codec PLL and to shut down the audio PLLs on the i.MX8MQ SoC side.

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.
