The correct way to address this would appear to be to add link-frequencies
for both of these devices. I think I've seen one or two sensors of this
class (raw, CSI-2/parallel, external clock etc.) with link frequencies
documented as "fixed" --- which is probably a documentation issue more than
anything else.
