Describe the RPCSRC internal clock and the RPC[D2] clocks derived from it, as well as the RPC-IF module clock, in the RZ/G2E (R8A774C0) CPG/MSSR driver. Add new clk type CLK_TYPE_GEN3_E3_RPCSRC to register rpcsrc as a fixed clock on R-Car Gen3 E3 (and also RZ/G2E which is identical to E3 SoC), parent and the divider is set based on the register value CPG_RPCCKCR[4:3] which has been set prior to booting the kernel.

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.
