LTDC 40100 hw version supports the YCbCr 422 output, reducing the output pins from 24 to 16. This feature is useful for some external devices like HDMI bridges. Both ITU-R BT.601 & ITU-R BT.709 are supported. It is also possible to choose the chrominance order between * Cb is output first (Y0Cb, then Y1Cr, Y2Cb and so on). * Cr is output first (Y0Cr, then Y1Cb, Y2Cr and so on).

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.
