Ah, ok. We didn't recognise this before. 6 eyes see more than 4...
I just did cherry-pick this old 4.0 patch from 2015 by Zubair
and it created a ingenic-jz4780-lcd.txt:
https://lore.kernel.org/patchwork/patch/547872/
and Sam was so kind to convert it to yaml.

Yes that is true.

Agreed. That was suggested by Sam.

Ok, I think I'll review all so that it does match/replace
Documentation/devicetree/bindings/display/ingenic,lcd.txt
and no information is lost.
