MQS (medium quality sound), is used to generate medium quality audio via a standard digital output pin. It can be used to connect stereo speakers or headphones simply via power amplifier stages without an additional DAC chip. It only accepts 2-channel, LSB-valid 16bit, MSB shift-out first, frame sync asserting with the first bit of the frame, data shifted with the posedge of bit clock, 44.1 kHz or 48 kHz signals from SAI1 in left justified format; and it provides the SNR target as no more than 20dB for the signals below 10 kHz. The signals above 10 kHz will have worse THD+N values. MQS provides only simple audio reproduction. No internal pop, click or distortion artifact reduction methods are provided. The MQS receives the audio data from the SAI1 Tx section.

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.
