Not for mainline.  I'd suggest setting it up for extcon anyway
especially if it's just a simple accessory, that should work for both
Android and mainline.

Oh, right.  If this is doing what I think this is doing you want to use
DAPM within the CODEC then this can just become a pin switch or you can
hook in directly if you continue to use soc-jack - it has DAPM
integration.
