mainlining shenanigans

The DP spec says: "When the combination of the requested pre-emphasis level and voltage swing exceeds the capability of a DPTX, the DPTX shall set the pre-emphasis level according to the request and use the highest voltage swing it can output with the given pre-emphasis level." and "When a DPTX reads a request beyond the limits of this Standard, the DPTX shall set the pre-emphasis level according to the request and set the highest voltage swing level it can output with the given pre-emphasis level. If a DPTX is requested for 9.5dB of pre-emphasis level (may be supported for a DPTX) and cannot support that level, it shall set the pre-emphasis level to the next highest level, 6dB." Ie. we should first validate the pre-emphasis, and then select the appropriate vswing for it.

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.
