2f7f0994cc Allow detecting ACP6x DMIC via _DSD 
Merge series from Mario Limonciello <mario.limonciello@amd.com>:

It's not possible to probe for the presence of a DMIC, so the ACP6x
machine driver currently has a hardcoded list of all the systems known
to have a DMIC connected to the ACP.

Although this design works it means that the acp6x driver needs to always
grow with more systems and worse, if an OEM introduces a new system there
will be a mismatch in time that even if the driver (otherwise) works fine
it needs their system added to the list to work.

So this series introduces a _DSD that OEMs can populate into the BIOS to
indicate presence of a DMIC.

5426f506b5 ASoC: amd: Add support for enabling DMIC on acp6x via _DSD 
Currently the acp6x machine driver requires a hardcoded list of systems
that physically have DMIC connected.

To avoid having to continually add to an evergrowing list of systems add
support for a _DSD that can advertise this.

OEMs can add this _DSD to their BIOS under the ACP device to automatically
add the device to this driver without requiring any driver modifications.

e521f08778 ASoC: amd: Add driver data to acp6x machine driver 
Currently all of the quirked systems use the same card and so the
DMI quirk list doesn't contain driver data.

Add driver data to these quirks and then check the data was present
or not.  This will allow potentially setting quirks for systems with
faulty firmware that claims to have a DMIC but doesn't really.

7bef00106b ASoC: amd: acp6x-pdm-dma: Constify static snd_soc_dai_ops 
The only usage of acp6x_pdm_dai_ops is to assign its address to the ops
field in the snd_soc_dai_driver struct, which is a pointer to const
snd_soc_dai_ops. Make it const to allow the compiler to put it in
read-only memory.
