Instead of open coding, use the mipi_dsi_pixel_format_to_bpp() helper function from drm_mipi_dsi.h in mtk_dsi_poweron() and for validation in mtk_dsi_bridge_mode_valid(). Note that this function changes the behavior of this driver: previously, in case of unknown formats, it would (wrongly) assume that it should account for a 24-bits format - now it will return an error and refuse to set clocks and/or enable the DSI. This is done because setting the wrong data rate will only produce a garbage output that the display will misinterpret both because this driver doesn't actually provide any extra-spec format support and/or because the data rate (hence, the HS clock) will be wrong.

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.
