The datasheet of V3s (and various other chips) wrote that TCON0_DCLK_DIV can be >= 1 if only dclk is used, and must >= 6 if dclk1 or dclk2 is used. As currently neither dclk1 nor dclk2 is used (no writes to these bits), let's set minimal division to 1. If this minimal division is 6, some common dot clock frequencies can't be produced (e.g. 30MHz will not be possible and will fallback to 25MHz), which is obviously not an expected behaviour.

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.
