The custom clock driver that models the PLL clocks on R-Car Gen4 supports only fractional 8.25 PLLs, as used on R-Car V4H/V4M. R-Car S4-8 uses integer and fractional multiplication fields that are one bit larger resp. smaller, and a slightly different formula. Extend the existing support to fractional 9.24 PLL, and introduce new clock types and helper macros to describe these PLLs. Note that there is no use case for variable fractional 9.24 PLLs yet, as the Cortex-A55 cores on R-Car S4-8 do not support High Performance mode. Hence the PLL is always modeled as a fixed PLL, regardless of the description, Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Reviewed-by: Yoshihiro Shimoda <yoshihiro.shimoda.uh@renesas.com> Link: https://lore.kernel.org/5684eda1260435c8eceabc274e0b18cb280a6341.1721648548.git.geert+renesas@glider.be |

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 reStructuredText 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.
