Currently the best variant picked in the first one in the list provided in the manufacturer driver. This worked well while all operations where performed at the same speed, but with the introduction of DTR transfers and per operation maximum frequencies, this no longer works correctly. Let's continue iterating over all the alternatives, even if we find a match, keeping a reference over the theoretically fastest operation. Only at the end we can tell which variant is the best. This logic happening only once at boot, the extra computing needed compared to the previous version is acceptable wrt. the expected improvements.

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.
