The input-layer supports the following switches:


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.
