Similar comments to the Maxim driver plus...

Don't do this - if the functionality isn't there in the CODEC driver get
it implemented before you use it.  Make sure you're using the API the
CODEC actually ends up exporting.

No, don't do this - as discussed in another Chromebook review (I'm
guessing this is a Chromebook) the jacks should represent the physical
jacks in the system.  It's possible you have separate headphone and
microphone jacks but I really expect microphone and button to be on the
same socket.
