The dsi has several constraints on the video modes it can support, mainly due to the frequencies that can be generated by the PLL integrated in the DSI device. Verify that the required HS clock can be generated by the PLL. The dsi clock from the dsi PLL and the ltdc pixel clock are asynchronous. The dsi needs to return in LP mode during HFP or HBP to re-synchronize at each video line. Verify that the duration of HFP and HBP allows the dsi to enter in LP mode.

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.
