[Why] eDP v1.4 allows panels to report link rates other than RBR/HBR/HBR2, that may be more optimal for the panel's timing. Power can be saved by using a link rate closer to the required bandwidth of the panel's timing. [How] Scan the table of reported link rates from the panel, and select the minimum link rate that satisfies the bandwidth requirements of the panel's timing. Include a flag to make the feature optional.

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.
