I mean, the main reason fbtft was in staging all this time has never
been about fbdev. It was about the device tree bindings that have never
been documented, reviewed and agreed upon. And given its bindings, we're
very far from it.

That's what Noralf has been mostly working on all this time, and yeah,
it takes time but we're getting there.
