The MSM DRM driver currently does not support panels which report their supported link rates via the SUPPORTED_LINK_RATES table. For panels which do not offer the optional eDP v1.3 fallback via MAX_LINK_RATE, this will cause a panel probe failure (e.g. Samsung ATNA30DW01-1 as found in Microsoft Surface Pro 11). Detect eDP v1.4 panels and parse the SUPPORTED_LINK_RATES table when present. Additionally, set the rate using LINK_RATE_SET instead of LINK_BW_SET, but only if LINK_BW_SET hasn't already been written to.

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.
