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.
