[PATCH v4 0/3] Add support for different DMIC configurations
Set of patches to enable DMIC capture on different hardware configurations. Information about supported DMIC configuration is read from NHLT and correct pipeline configuration is selected automatically. Also, adding additional option for topology binary name which is based on used machine driver.
Changes in v2: - removed patch 1/4 swapping machine device and platform device registration order - alt_tplg_name creation now uses different field to read machine driver name - including of <sound/soc-acpi.h> moved to different patch
Changes in v3: - cosmetic changes in skl-topology.c file
Changes in v4: - refactored patch 2/3 to use one common helper function to deal with both set and get pipe configuration operations, as suggested by Pierre - adjusted patch 3/3 to also use this helper function for DMIC pipes - added comment in patch 3/3 explaining the change of access rights for DMIC enums

Add alternative topology binary file name based on used machine driver and fallback to use this name after failed attempt to load topology file with name based on NHLT. This change addresses multiple issues with current mechanism, for example - there are devices without NHLT table, and that currently results in tplg_name being empty.

For pipes supporting multiple input/output formats, kcontrol is created and selection of pipe input and output configuration is done based on control set.
If more than one configuration is supported, then this patch allows user to select configuration of choice using amixer settings.

There was, changed in v5.

Automatically choose DMIC pipeline format configuration depending on information included in NHLT. Change the access rights of appropriate kcontrols to read-only in order to prevent user interference.

Neither this posting nor the last posting seem to have managed to send me a copy of patch 2.
The only reason I can think of is the fact, that one of Signed-by tags in patch 2/3 had a comma in it and git send-patch added one additional, invalid CC recipient.
I have adjusted that Signed-by tag in patchset v5.
