rspi_rz_set_config_register() favors high values of "brdv" over high values of "spbr". As "brdv" is not a plain divider, but controls a power-of-two divider, this may cause the selection of non-optimal divider values. E.g. on RSK+RZA1, when 3.8 MHz is requested, the actual configured bit rate is 2.08 MHz (spbr = 1, brdv = 3), while 3.7 MHz would be possible (spbr = 8, brdv = 0). Fix this by only resorting to higher "brdv" values when really needed. This makes the driver always pick optimal divider values on RZ/A.

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.
