3.13 Headset Jack Interface
3-pole type ear-mic jack which has three electrodes such as R, Mic+, and GND.
This type usually supports only single-ended configuration (VOUTAUXP for headset speaker
and VINAUXP for headset mic) in the audio path.
There are two control signals for jack interface. One is JACK_DETECT which is for detecting
the headset jack and the other is HOOK_DETECT which is enabled when hook of the head-
set is pressed. The pins (JACK_DETECT and HOOK_DETECT) interfaces with AD6525.
