The generic ALSA part of the API has been merged already - see
include/sound/jack.h.
For ASoC drivers you need to implement the actual detection in your
machine driver. Normally this would just hook into a GPIO. You can
then update the DAPM widget for the jack to mark it as in use or not in
use (some existing drivers do this) and also hook into the generic
userspace API (that's not been implemented by anyone yet). Plan is to
get something more generic into 2.6.30.
