Yes I know that but the thing is that the current binding don't describe
the hardware correctly. For instance, don't use a backlight DT node as a
property of the panel and have this "fb" suffix in the compatible strings.
Having said that, my opinion is that we should just keep with the existing
bindings and make compatible to that even if isn't completely correct.
Since that will ease adoption of the new DRM driver and allow users to use
it without the need to update their DTBs.
