I would go by the part number, the way fsl/nxp is handled: the parts
that came out of Cortina Systems with a CSxxxx number keep "cortina",
so "cortina,cs8032", and the CAxxxx parts that Cortina Access designed
use "cortina-access". That gives a rule a later submitter can apply
without knowing who sells the chip today.

Jason, if Cortina Access would rather see its current CS80xx/CS81xx
parts under "cortina-access", now would be the time to say so; I have
no stake in those and only need a rule for the CS75xx.

Thanks,
