The decision to use DFP output format conversion capabilities should be during compute_config phase. This patch adds new member to crtc_state to represent the final output_format to the sink. In case of a DFP this can be different than the output_format, as per the format conversion done via the PCON. This will help to store only the format conversion capabilities of the DP device in intel_dp->dfp, and use crtc_state to compute and store the configuration for color/format conversion for a given mode. v2: modified the new member to crtc_state to represent the final output_format that eaches the sink, after possible conversion by PCON kind of devices. (Ville) v3: Addressed comments from Ville: -Added comments to clarify difference between sink_format and output_format. -Corrected the order of setting sink_format and output_format. -Added readout for sink_format in get_pipe_config hooks. v4: Set sink_format for intel_sdvo too. (Ville) v5: Rebased. v6: Fixed condition to go for YCbCr420 format for dp and hdmi. (Ville) v7: Fix the condition to set sink_format for HDMI. Set hdmi output_format simply as sink_format.

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.
