The mode parsing is currently implemented in three steps: of_get_display_timing() - DT panel-timing to struct display_timing videomode_from_timing() - struct display_timing to struct videomode drm_display_mode_from_videomode() - struct videomode to struct drm_display_mode Replace all that with simple of_get_drm_panel_display_mode() call, which already populates struct drm_display_mode and then duplicate that mode in panel_lvds_get_modes() each time, since the mode does not change. Nice bonus is the bus_flags parsed by of_get_drm_panel_display_mode() out of panel-timing DT node, which is used in subsequent patch to fix handling of 'de-active' DT property.

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.
