[PATCH v2 0/9] ASoC: qdsp6: audioreach: add multi-port, SAL and MFC support

[Srinivas Kandagatla]

This patchset adds support to multi-port connections between AudioReach Modules
which is required for sophisticated graphs like ECNS or Speaker Protection.
Also as part of ECNS testing new module support for SAL and MFC are added.


Tested on SM8450 with ECNS.

Thanks,
Srini

Changes since v1:
	Fixed two warnings on unused and unintialized variable.

[PATCH v2 1/9] ASoC: qdsp6: audioreach: topology use idr_alloc_u32

[Srinivas Kandagatla]

SubGraph and Module Instance ids take 32 bits, so use idr_alloc_u32
instead of idr_alloc to able to accomdate valid ranges.

typo: accommodate.

Also worth checking https://www.kernel.org/doc/html/latest/core-api/idr.html

Thanks for this hit, this looks really good and specially lookups 
without Locking, this could cleanup the code a bit.

Having said that I would still like this patch go as it is with idr for 
now, and I can plan to rework on converting idr to xa later, as there 
are few more Qcom Audio drivers that have usage of idr.

thanks,
srini

[Srinivas Kandagatla]

Update kcontrol private date to include more information like graph id
and module instance id which its connected to. Also maintain this virtual
dapm mixer widget in a list so that we could lookup while FE and BE connection
are added.

[PATCH v2 4/9] ASoC: qdsp6: audioreach: Simplify handing FE and BE graph connections

[Srinivas Kandagatla]

Current AudioReach design of connecting FE and BE graph is very complicated
and not reliable. Instead used the virtual damp widgets private data to help
identify the modules that needs connection at runtime. Also maintain a
inter-graph connection info in the graph info, which can be used to both
determine if the graphs are connected and at graph build time.

[PATCH v2 6/9] ASoC: qdsp6: audioreach: add support for more port connections

[Srinivas Kandagatla]

AudioReach Modules can connect to other modules using source and
destination port, and each module in theory can support up to 255 port
connections. But in practice this limit is at max 8 ports at a time.
So add support for allowing multiple port connections.

This support is needed for more detailed graphs like ECNS, speaker
protection and so.
