The Renesas RZ/T2H (R9A09G077) and RZ/N2H (R9A09G087) SoCs have a more complicated clocking setup for the SPI transfer clock than RZ/V2H, as the clock from which it is generated supports multiple dividers. To prepare for adding support for these SoCs, split out the logic for finding the SPR and BRDV for a fixed clock into rzv2h_rspi_find_rate_fixed(), and add and use a .find_tclk_rate() callback into the chip-specific structure.

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.
