[PATCH 16/27] ASoC: mediatek: mt8183-da7219-max98357: Map missing jack kcontrols

From: Alper Nebi Yasak
Date: Wed Aug 02 2023 - 13:59:22 EST


This driver does not properly map jack pins to kcontrols that PulseAudio
and PipeWire need to handle jack detection events. The DA7219 codec used
here can detect Headphones, Headset Mic and Line Out connections. Expose
each to userspace as kcontrols and add the necessary widgets.
