When YCBCR 4:2:0 outputs is used for DP, we should program YCBCR 4:2:0 to MSA and VSC SDP. As per DP 1.4a spec section 2.2.4.3 [MSA Field for Indication of Color Encoding Format and Content Color Gamut] while sending YCBCR 420 signals we should program MSA MISC1 fields which indicate VSC SDP for the Pixel Encoding/Colorimetry Format. v2: Block comment style fix. v6: Fix an wrong setting of MSA MISC1 fields for Pixel Encoding/Colorimetry Format indication. As per DP 1.4a spec Table 2-96 [MSA MISC1 and MISC0 Fields for Pixel Encoding/Colorimetry Format Indication] When MISC1, bit 6, is Set to 1, a Source device uses a VSC SDP to indicate the Pixel Encoding/Colorimetry Format. On the wrong version it set a bit 5 of MISC1, now it set a bit 6 of MISC1.

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.
