Subject: [PATCH] ASoC: Intel: Skylake: Support Pipeline Properties IPC
|
|
|
|
Add support to query te properties of any pipeline, that is
|
|
running in te ADSP. This ipc involves sending the
|
|
pipe id for which properties is sought for.
|
|
This IPC is supported in a TLV format and so the
|
|
associated changes in the framework are done.
|
|
Typical syntax from a debugfs standpoint is
|
|
echo 11,<pipeid> > adsp_prop_ctrl
|
|
|
|
