The MCDE driver differentiates only between "te_sync"
(for hardware TE0 sync) and software sync
(i.e. manually triggered updates) at the moment.
However, none of these options work correctly for video mode panels.
Therefore, we need to make some changes to make them work correctly:
- Select hardware sync coming from the (DSI) formatter.
- Keep the FIFO permanently enabled (otherwise MCDE will stop
feeding data to the panel).
- Skip manual software sync (this is not necessary in video mode).
Automatically detect if the connected panel is using video mode
and enable the necessary changes in that case.

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.
