I point you to this Thread and back:
https://lists.freedesktop.org/archives/dri-devel/2018-March/170688.html

I did the same for rgb888, so good part is discussed.

IMHO I would:
- call lcd0_rgb666_pins, since this is for LCD0 interface
- same as above, call lcd0-rgb666, take care about using "-" instad of
"_" that can cause DTC warnings.
- remove @0 since only this set can achieve LCD0 RGB666, and I
don't think there will be other combinations.

Kind regards
