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.
