I'm not sure why you'd need different timings if the only difference
is the bus width.

And this isn't a different device, it's just the integration in the
board that is different, so you shouldn't have a different compatible
here, but rather something like the bus-width property documented in
the Documentation/devicetree/bindings/media/video-interfaces.txt file.
