The Linux Arizona driver uses the MFD framework to create several sub-devices for the Arizona codec and then uses a driver per function. The extcon-arizona driver handles jack-detect support and exports info about the jack state to userspace through the standard extcon sysfs class interface. Standard Linux userspace does not monitor/use the extcon sysfs interface for jack-detection, resulting in the jack-state not being taken into account by userspace. The ASoC machine-driver may have created a standard ASoC jack when registering the card. In this case also report the jack-state through the ASoC jack so that jack-detection works with standard Linux userspace.
