Three operating mode are available to convey the graphical data to the display: - Video mode streams over the high-speed link the RGB data and the associated synchronization signals directly generated by the LCDC. The streaming starts as soon as the DSI Host and the LCDC are enabled. This continuous refresh is the best way to interface with a display without Graphics RAM. - APB command mode sends commands over the high-speed link for configuration as it is done using a legacy serial interface (SPI). The commands are launched using the DSI Host APB interface. - Adapted command mode is the best way to interface with a display having its own internal Graphics RAM. The DSI Host captures only one full frame coming from the LCDC and transforms it into a series of write commands to update the display Graphics RAM.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
