[PATCH 02/27] ASoC: amd: acp-rt5645: Map missing jack kcontrols

From: Alper Nebi Yasak
Date: Wed Aug 02 2023 - 13:58:23 EST


This driver does not properly map jack pins to kcontrols that PulseAudio
and PipeWire need to handle jack detection events. The RT5645 codec used
here can detect Headphone and Headset Mic connections. Expose both to
userspace as kcontrols.
