Subject: [PATCH v21 26/39] ASoC: qcom: qdsp6: Add support to track available USB PCM devices
Date: Tue, 7 May 2024 12:51:03 -0700 [thread overview]
Message-ID: <20240507195116.9464-27-quic_wcheng@quicinc.com> (raw)
In-Reply-To: <20240507195116.9464-1-quic_wcheng@quicinc.com>
The USB backend should know about which sound resources are being shared
between the ASoC and USB SND paths. This can be utilized to properly
select and maintain the offloading devices.
