The driver previously checked each transfer if the requested speed was higher than possible with the current spi clock rate and raised the clock rate accordingly. However, there is no check to see if the spi clock was actually set that high and no way to dynamically lower the spi clock rate again. So it seems any potiential users of this functionality are better off just setting the spi clock rate at init using the assigned-clock-rates devicetree property. Removing this dynamic spi clock rate raising allows us let the spi framework handle min/max speeds for us.

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.
