The Asia Better Technology (ABT) Y030XX067A panel is a 3.0" 320x480
24-bit IPS LCD panel. Its particularity is that it has non-square
pixels
(as it is 4:3 for a resolution of 320x480), and that it requires odd
lines to be sent as RGB and even lines to be sent as GRB on its
8-bit
bus.

The binding is missing:
required:
- compatible
- reg
- power-supply
- reset-gpios
- ...
additionalProperties: false
So r-b only with these added.
Stupid mistake, sorry about that.
I'll V2.
