+title: Qualcomm ASoC DPCM USB backend DAI
+
+maintainers:
+ - Wesley Cheng <quic_wcheng@quicinc.com>
+
+description:
+ The USB port is a supported AFE path on the Q6 DSP. This ASoC DPCM
+ backend DAI will communicate the required settings to initialize the
+ XHCI host controller properly for enabling the offloaded audio stream.
+ Parameters defined under this node will carry settings, which will be
+ passed along during the QMI stream enable request and configuration of
+ the XHCI host controller.
