TCON0's source clock can be fed from either PLL_MIPI, or PLL_VIDEO0(2X), however MIPI DSI output only seems to work when PLL_MIPI is selected and thus the choice must be hardcoded in. Currently, this driver can't propagate rate change from N-K-M clocks (such as PLL_MIPI) upwards. This prevents PLL_VIDEO0 from participating in setting of the TCON0 data clock rate, limiting the precision with which a target pixel clock can be matched. For outputs with fixed TCON0 divider, that is DSI and LVDS, the dotclock can deviate up to 8% off target.

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.
