This patch adds support to read and store the DSC capabilities of the HDMI2.1 PCon encoder. It also adds a new field to store these caps, The caps are read during dfp update and can later be used to get the PPS parameters for PCON-HDMI2.1 sink pair. Which inturn will be used to take a call to override the existing PPS-metadata, by either writing the entire new PPS metadata, or by writing only the PPS override parameters. v2: Restructured the code to read all capability DPCDs at once and store in an array in intel_dp structure. v3: rebase Signed-off-by: Ankit Nautiyal <ankit.k.nautiyal@intel.com> Reviewed-by: Uma Shankar <uma.shankar@intel.com> [Jani: Fixed checkpatch PARENTHESIS_ALIGNMENT.] Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20201218103723.30844-13-ankit.k.nautiyal@intel.com
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.
