The rt5682 codec is able to distinguish between two event types: headphone insertion/removal and headset microphone insertion/removal. However, currently, the mt8195 ASoC driver exposes a single kcontrol for the headset jack, so userspace isn't able to differentiate between the two events. Add a definition for the headset jack pins, so that a separate jack kcontrol is created for each one, allowing userspace to track and handle them individually. Signed-off-by: Nícolas F. R. A.
