Subject: [PATCH 10/14] extcon: arizona: Also report jack state through
|
|
snd_soc_jack_report()
|
|
|
|
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.
