The RPCSRC internal clock is controlled by the RPCCKCR.DIV[4:3] on all the R-Car gen3 SoCs except V3M (R8A77970) but the encoding of this field is different between SoCs; it makes sense to support the most common case of this encoding in the R-Car gen3 CPG driver... After adding the RPCSRC clock, we can add the RPC[D2] clocks derived from it and controlled by the RPCCKCR register on all the R-Car gen3 SoCs except V3M (R8A77970); the composite clock driver seems handy for this task, using the spinlock added in the previous patch...

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.
