When a source supporting DSC1.1 is connected to DSC1.2 HDMI2.1 sink via DP HDMI2.1 PCON, the PCON can be configured to decode the DSC1.1 compressed stream and encode to DSC1.2. It then sends the DSC1.2 compressed stream to the HDMI2.1 sink. This patch configures the PCON for DSC1.1 to DSC1.2 encoding, based on the PCON's DSC encoder capablities and HDMI2.1 sink's DSC decoder capabilities. v2: Addressed review comments from Uma Shankar: -fixed the error in packing pps parameter values -added check for pcon in the pcon related function -appended display in commit message v3: Only consider non-zero DSC FRL b/w for determining max FRL b/w supported by sink.

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.
