To repeat my previous question which I don't seem to see a response to:

I am not sure why Naveen didn't respond, I will ask around.

FWIW the userspace in question is CRAS. CRAS wants to manage MICs and would
*know* how many MICs are on the board and would work with PCM data
accordingly...

My Bad, my apologies to Mark.
I did try replying but message wasn't sent from my outbox which I'm noticing
today after vinod's mail to Mark.
Sorry about missing this, it's due to mutt configuration in linux that got
corrupted recently in my work-mac, making my replies for patches un-sent.

Regarding the Query:
As Vinod mentioned, I'm working on Chrome OS user-space stack that uses
customized audio server "CRAS".
These patches are verified on a board that has only 2 dmics.

Giving the control to CRAS, enables to select the desired dmic using
channel-map configuration in user-space.
Ex:Rear/Front mic selection for World & Front facing camera scenario

People do run non-ChromeOS installs on their Chromebooks so we can't
just assume that there's nobody out there with a regular distro on this
hardware - a user like this reported the problems with the ABI for
topology files breaking for example.

Understood the point,
shall discuss and work internally with team and reply back. Thanks
