Adding jack-detect support may seem weird for a codec with only a single output, but it is necessary. The ES8316 appnote showing the intended usage uses a jack-receptacle which physically disconnects the speakers from the output when a jack is plugged in.
But all 3 devices using the es8316 which I have (2 Cherry Trail devices and one Bay Trail CR device), use an analog mux to disconnect the speakers, driven by a GPIO. In order to enable/disable the speakers at the right time, we need jack-detect.
The same goes for the microphone where we must correctly set the mux for the single ADC to either the internal or the headset microphone.
All devices I have support the es8316's builtin jack-detect functionality.
