Hi Conor
Thanks for the incredibly speedy review.

I'm happy to drop it, just that I've seen a number of media bindings
that had debate on why extra compatible strings were required.

I'll freely admit that DT bindings are a black art to me, so I was
following sony,imx290.yaml [1].
properties:
compatible:
oneOf:
- enum:
- sony,imx290lqr # Colour
- sony,imx290llr # Monochrome
- sony,imx327lqr # Colour
- const: sony,imx290
deprecated: true
Looking again at that case, I assume the oneOf is selecting between
the enum and the const? Seeing as we don't have the const, I guess we
can drop the "oneOf:"
Thanks for your help.
