This is a good patch. I hope CDF also makes sure the Display controller 
and DSI bus are made more independent in this manner.

One thing which we should eventually add is to ensure that 
omap_dsi_update() for command mode panels is called only after 
dsi_enable_video_output() is called. I think we manage this in our panel 
driver, but maybe some sort of check could help there.
