Linux kernel source tree

Otherwise when when clk_i2s0 muxes to clk_i2s0_div which requires setting high divider value on clk_i2s0_div, and then muxes back to clk_i2s0_frac, clk_i2s0_frac would have no way to change the clk_i2s0_div's divider ratio back to 1 so that it can satisfy the condition for m/n > 20 for fractional division to work correctly. Bug is reproducible by playing 44.1k audio, then 48k audio, and then 44.1k audio again. This results in clk_i2s0_div being set to 49 and clk_i2s0_frac not being able to cope with such a low input clock rate and audio playing extremely slowly. The identical issue is on i2s1 and i2s2 clocks, too.

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.
