[ Upstream commitc258e3ab63] As serial communication requires a clean clock signal, the High Speed Serial Communication Interfaces with FIFO (HSCIF) are clocked by a clock that is not affected by Spread Spectrum or Fractional Multiplication. Hence change the parent clocks for the HSCIF modules from the S0D3_PER clock to the SASYNCPERD1 clock (which has the same clock rate), cfr. R-Car S4-8 Hardware User's Manual rev. 0.81.

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.
