Merge series "ASoC: qcom: Add AudioReach support" from Srinivas Kandagatla <srinivas.kandagatla@linaro.org>:
Hi Mark,
This version is a respin of v10 fixing a build error in 12/17 patch.
QCOM SoC relevant non-audio patches in this series has 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@linaro.org
This patchset adds ASoC driver support to configure signal processing
framework ("AudioReach") which is integral part of Qualcomm next
generation audio SDK and will be deployed on upcoming Qualcomm chipsets.
It makes use of ASoC Topology to load graphs on to the DSP which is then
managed by APM (Audio Processing Manager) service to prepare/start/stop.
Here is simplified high-level block diagram of AudioReach:

AudioReach has constructs of sub-graph, container and modules.
Each sub-graph can have N containers and each Container can have N Modules
and connections between them can be linear or non-linear.
An audio function can be realized with one or many connected
sub-graphs. There are also control/event paths between modules that can
be wired up while building graph to achieve various control mechanism
between modules. These concepts of Sub-Graph, Containers and Modules
are represented in ASoC topology.
Here is simple I2S graph with a Write Shared Memory and a
Volume control module within a single Subgraph (1) with one Container (1)
and 5 modules.
____________________________________________________________
| Sub-Graph [1] |

| | Container [1] | |
| | [WR_SH] -> [PCM DEC] -> [PCM CONV] -> [VOL]-> [I2S-EP]| |
| |_______________________________________________________| |
|____________________________________________________________|
For now this graph is split into two subgraphs to achieve dpcm like below:
________________________________________________ _________________
| Sub-Graph [1] | | Sub-Graph [2] |
| ____________________________________________ | | _____________ |
| | Container [1] | | | |Container [2]| |
| | [WR_SH] -> [PCM DEC] -> [PCM CONV] -> [VOL]| | | | [I2S-EP] | |
| |____________________________________________| | | |_____________| |
|________________________________________________| |_________________|
_________________
| Sub-Graph [3] |
| _____________ |
| |Container [3]| |
| | [DMA-EP] | |
| |_____________| |
|_________________|
This patchset adds very minimal support for AudioReach which includes
supporting sub-graphs containing CODEC DMA ports and simple PCM
Decoder/Encoder and Logger Modules. Additional capabilities will
be built over time to expose features offered by AudioReach.
This patchset is Tested on SM8250 SoC based Qualcomm Robotics Platform RB5
and SM9250 MTP with WSA881X Smart Speaker Amplifiers, DMICs connected via
VA Macro and WCD938x Codec connected via TX and RX Macro and HDMI audio
via I2S.
First 10 Patches are mostly reorganization existing Old QDSP Audio
Framework code and bindings so that we could reuse them on AudioReach.
ASoC topology graphs for DragonBoard RB5 and SM8250 MTP are available at
https://git.linaro.org/people/srinivas.kandagatla/audioreach-topology.git/
and Qualcomm AudioReach DSP headers are available at:
https://source.codeaurora.org/quic/la/platform/vendor/opensource/arspf-headers
Note: There is one false positive warning in this patchset:
audioreach.c:80:45: warning: array of flexible structures
Thanks,
srini
