Add operating points for running the Cortex-A55 CPU cores on R-Car S4-8 at various speeds, up to the maximum supported frequency (1200 MHz). R-Car S4-8 has 8 Cortex-A55 cores, grouped in 4 clusters. CA55 Sub-System 0 (first 2 clusters / CPU cores 0-3) is clocked by Z0φ. CA55 Sub-System 1 (last 2 clusters / CPU cores 4-7) is clocked by Z1φ. As the two sets of clusters are driven by separate clocks, this requires specifying two separate tables (using the same operating performance point values), with "opp-shared" to indicate that the CPU cores in each set share state. Based on a patch in the BSP by Tho Vu.

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.
