Hi everyone,
I've finally started looking into the cfb_console.c driver and it's conversion to DM_VIDEO after our initial discussion [1]. Unfortunately I've a bit underestimated the amount of effort that should be done, as mxsfb.c in the Linux mainline obviously pulls the whole core fb subsystem (drivers/video/fbdev/core), which can take a while and frankly I doubt that this is a proper way to do things here.
Just wanted to mention that the Linux mxsfb fbdev driver is considered deprecated.
See: https://lore.kernel.org/patchwork/patch/950619/#1135990
Also note that the new DRM driver does use OF graph style bindings, see: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Docu...
Taking into account that the deadline for DM_VIDEO conversion is 2019.07, it's unlikely that we will manage to do the full conversions this cfb_console driver and all dependent hw specific drivers in a proper way (where we can provide information about videomodes as properties in a proper nodes in DT).
IMHO, if the deadline hinders us to do it properly, we should extend the deadline.
Agreed. We can always extend deadlines as needed when people are working to solve the problem, and we want it solved correctly. Thanks all!

Stefan, Anatolij, Tom,
Thanks a lot for your input!
Just want to mention that I am in full agreement with what was said here :-)
