As serial communication requires a clean clock signal, the Serial
Communication Interfaces with FIFO (SCIF) are clocked by a clock that is
not affected by Spread Spectrum or Fractional Multiplication.
Hence change the parent clocks for the SCIF modules from the S0D12_PER
clock to the SASYNCPERD4 clock (which has the same clock rate), cfr.

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.
