Subject: [PATCH v19 34/41] ASoC: qcom: qdsp6: Add headphone jack for offload connection status
Date: Mon, 22 Apr 2024 15:48:59 -0700	[thread overview]
Message-ID: <20240422224906.15868-35-quic_wcheng@quicinc.com> (raw)
In-Reply-To: <20240422224906.15868-1-quic_wcheng@quicinc.com>

The headphone jack framework has a well defined infrastructure for
notifying userspace entities through input devices.  Expose a jack device
that carries information about if an offload capable device is connected.
Applications can further identify specific offloading information through
other SND kcontrols.
