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
