[Srinivas Kandagatla]

On AudioReach audio Framework, Audio Streams (PCM/Compressed) are managed by
Q6APM(Audio Process Manager) service. This patch adds bindings for this DAIs
exposed by the DSP.

Hi Rob, 

You might see a dt_binding_check errors as QCOM SoC relevant non-audio patches
in this series have been merged into the Qualcomm drivers-for-5.16 tree,
as this series depends those patches an immutable tag is available at:
https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux.git
tags/20210927135559.738-6-srinivas.kandagatla at linaro.org

thanks,
srini
