If PCON has capability to convert RGB->YCbCr colorspace and also to 444->420 downsampling then for any YUV420 only mode, we can let the PCON do all the conversion. If the PCON supports RGB->YCbCr conversion for all BT2020, BT709, BT601, choose the one that is selected by userspace via connector colorspace property, otherwise default to BT601. v2: As suggested by Uma Shankar, considered case for colorspace BT709 and BT2020, and default to BT601. Also appended dir 'display' in commit message. v3: Fixed typo in condition for printing one of the error msg. v4: As suggested by Uma Shankar: -Fixed bug in determining the colorspace for RGB->YCbCr conversion. -Fixed minor formatting issues Also updated the commit message as per latest changes.

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.
