Subject: [PATCH v3 00/25] ASoC: qcom: Add support to QDSP based Audio
From: Srinivas Kandagatla <srinivas.kandagatla@...aro.org>
This patchset aims to provide a basic version of QCOM DSP based
audio support which is available in downstream andriod kernels.
This patchset support audio playback on HDMI-RX, MI2S, SLIMBus and
will add support to other features as we move on.
QDSP has both static and dynamic modules. static modules like AFE
(Audio FrontEnd), ADM (Audio Device Manager), ASM(Audio Stream Manager)
and CORE to provide this audio services.
All these services use APR (Asynchronous Packet Router) protocol
via smd/glink transport to communicate with Application processor.
More details on each module is availble in there respective patch.
This patchset is tested on DB820c, with HDMI audio playback, MI2S on DB410c
on top of mainline, Also tested SLIMBus analog audio using wcd9355
with an additional patches.
Here is my test branch incase somone want to try these patches
