I'm not sure there's concensus on this one yet. I think so far the
driver decides which mode to use the panel in. Technically this falls
into the category of configuration, so it doesn't really belong in the
DT.
I vaguely recall from discussions I've had on this subject that there's
usually no reason to do video mode if you can do command mode because
command mode is more power efficient. This was a long time ago, so I may
be misremembering. Perhaps you have different information on this?
