[WHY] There are some monitor timings that seem to be supported without DSC but actually require DSC to be displayed. A VESA SCR introduced a new max uncompressed pixel rate cap register that we can use to handle these edge cases. [HOW] SST: Read caps from link and invalidate timings that exceed the max limit but do not support DSC. Then check for options override when determining BPP. MST: Read caps from virtual DPCD peer device or daisy chained SST monitor and set validation set BPPs to max if pixel rate exceeds uncompressed limit. Validation set optimization continues as normal.

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.
