How about this?
broken-cd: No CD available, use polling.
cd-gpios: The CD pin on the host is working and brought out to a GPIO.
external-cd-gpios: The CD pin on the host is broken, but there's an
independent external GPIO available.
(Each host should only have one of these properties.)
Thanks,
- Chris.
