Subject: [PATCH 22/27] ASoC: qcom: sdm845: Map missing jack kcontrols
Date:   Wed,  2 Aug 2023 20:57:32 +0300
Message-Id: <20230802175737.263412-23-alpernebiyasak@gmail.com>
In-Reply-To: <20230802175737.263412-1-alpernebiyasak@gmail.com>

This driver does not properly map jack pins to kcontrols that PulseAudio
and PipeWire need to handle jack detection events. The RT5663 codec used
here can detect Headphone and Headset Mic connections. Expose each to
userspace as a kcontrol.
