15fa179f3f ALSA: hda: Fill gaps in NHLT endpoint-interface
Two key operations missings are: endpoint presence-check and retrieval
of matching endpoint hardware configuration (blob). Add operations for
both use cases.

a14a621999 ALSA: hda: ignore invalid NHLT table
On some Lenovo systems if the microphone is disabled in the BIOS
only the NHLT table header is created, with no data. This means
the endpoints field is not correctly set to zero - leading to an
unintialised variable and hence invalid descriptors are parsed
leading to page faults.

The Lenovo firmware team is addressing this, but adding a check
preventing invalid tables being parsed is worthwhile.

Tested on a Lenovo T14.

a864e8f159 ALSA: hda: intel-nhlt: verify config type
Multiple bug reports report issues with the SOF and SST drivers when
dealing with single microphone cases.

We currently read the DMIC array information unconditionally but we
don't check that the configuration type is actually a mic array.

When the DMIC link does not rely on a mic array configuration, the
recommendation is to check the format information to infer the maximum
number of channels, and map this to the number of microphones.

This leaves a potential for a mismatch between actual microphones
available in hardware and what the ACPI table contains, but we have no
other source of information.

Note that single microphone configurations can alternatively be
handled with a 'mic array' configuration along with a 'vendor-defined'
geometry.

7318234c8d ASoC: Updates for v5.8
This has been another very active release with a bunch of new drivers,
 lots of fixes everywhere and continued core improvements from
 Morimoto-san:
 
  - Lots of core cleanups and refactorings from Morimoto-san, factoring
    out common operations and making the card abstraction more solid.
  - Continued work on cleaning up and improving the Intel drivers, along
    with some new platform support for them.
  - Fixes to make the Marvell SSPA driver work upstream.
  - Support for AMD Renoir ACP, Dialog DA7212, Freescale EASRC and
    i.MX8M, Intel Elkhard Lake, Maxim MAX98390, Nuvoton NAU8812 and
    NAU8814 and Realtek RT1016.

0d283287a4 ALSA: hda: Refactor Intel NHLT init
NHLT fetch based on _DSM prevents ACPI table override mechanism from
being utilized. Make use of acpi_get_table to enable it and get rid of
redundant code. In consequence, NHLT can be overridden just like any
other ACPI table, e.g.: DSDT or SSDT.

Change has been verified on all Intel AVS architecture platforms, RVP
and production laptops both.

Change possible due to addition of NHLT signature to the list of
standard ACPI tables:
https://patchwork.kernel.org/patch/11463235/

Override helps not only with debug purposes but also allows user for
table adjustment when one found on their production hardware is invalid.
Shared official NHLT spec is now available to community at:
https://01.org/blogs/intel-smart-sound-technology-audio-dsp

NHLT support for iASL is still ongoing subject but should be available
in nearest future.

82d9d54a6c ALSA: hda: add Intel DSP configuration / probe code
For distributions, we need one place where we can decide
which driver will be activated for the auto-configation of the
Intel's HDA hardware with DSP. Actually, we cover three drivers:

* Legacy HDA
* Intel SST
* Intel Sound Open Firmware (SOF)

All those drivers registers similar PCI IDs, so the first
driver probed from the PCI stack can win. But... it is not
guaranteed that the correct driver wins.

This commit changes Intel's NHLT ACPI module to a common
DSP probe module for the Intel's hardware. All above sound
drivers calls this code. The user can force another behaviour
using the module parameter 'dsp_driver' located in
the 'snd-intel-dspcfg' module.

This change allows to add specific dmi checks for the specific
systems. The examples are taken from the pull request:

  https://github.com/thesofproject/linux/pull/927

Tested on Lenovo Carbon X1 7th gen.
