Speyside makes use of support the WM8915 has for detecting the polarity of the microphone and ground connections on headsets, using a GPIO to control the polarity of the ground connection and switching between the two microphone bias supplies available on the device in order to do so. As a result of this the detection support is more involved than for most other CODECs, using a callback to configure the current polarity of the jack and translate this into the board-specific connections required for the current scenario. On Android some additional work is required to hook this up to the application layer as the Android HeadsetObserver monitors a custom drivers/switch API rather than the standard Linux APIs. This can be done by either updating HeadsetObserver or modifying the ALSA core to report via drivers/switch as well.
