Nice!
So, how should we get this done?
We have support for parsing individual lines of DT, and the primary
thing(s) needed by U-Boot's display are in the timing block of the
device tree, but I wonder whether it makes sense to implement a
full parser for that, or a simpler parser for fb_videomode.
Looks like the parser for fb_videomode is enough.
I am not familiar with the usage of device tree in U-boot yet.
How do other SoC families handle the video display-timings in dt
currently in U-boot?
AFAIK, with a full device-tree blob, but without any means of
updating it, which ends up in the same place as the compiled-in
settings.
In order to configure for a new kernel, you have to "compile"
the DTB and save it to the boot media.
This is a perfectly reasonable thing to do late in the development
process, but makes connecting new panels cumbersome.
Regards,
Eric
