I2S data sanity tests fail beyond a bit clock frequency of 6.144MHz.
This happens because the AHUB clock rate is too low and it shows
9.83MHz on boot.
The maximum rate of PLLA_OUT0 is 49.152MHz and is used to serve I/O
clocks. It is recommended that AHUB clock operates higher than this.
Thus fix this by using PLLP_OUT0 as parent clock for AHUB instead of
PLLA_OUT0 and fix the rate to 81.6MHz.

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.
