The input-layer supports the following switches:
SW_HEADPHONE_INSERT SW_MICROPHONE_INSERT SW_LINEOUT_INSERT SW_JACK_PHYSICAL_INSERT
Which is a 1:1 mapping with the cable-types currently exported by extcon-arizona.c .
I'm fine with fully moving extcon-arizona.c over to only using sound/core/jack.c functionality and it no longer exporting an extcon device.
I guess we should move it out of drivers/extcon then though. I suggest using: sound/soc/cirrus/arizona-jack-detect.c Note that sound/soc/cirrus is a new dir here. Would that work for you ?
And I guess we probably also want to change the MFD instantiated platform-dev's name to which it binds then?
I suggest using: "arizona-jack-detect" as new pdev name.
It will take me some time before I can make time to implement this, but this is a plan which I can get behind.
Regards,
Hans
