Ahh, sorry for misunderstanding you! Something like the following looks good ?
# Only required for SPI
dc-gpios:
description:
GPIO connected to the controller's D/C# (Data/Command) pin,
that is needed for 4-wire SPI to tell the controller if the
data sent is for a command register or the display data RAM
maxItems: 1
If you agree with that, then can squash before pushing or add it to a v4
if another revision is needed.
