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.)The fsl-imx-esdhc.txt binding already has all three cases, but describes them differently: fsl,cd-internal: when present, the CD pin on the host is working cd-gpios: when present, contains the gpio line that CD is connected to If both are absent, it has to use polling.
