Througout 2019, 2020 and 2021 Skylake-driver has had many fixes applied
and even attempts of refactors as seen in fundamental overhaul [3], IPC
flow adjustments [4] and LARGE_CONFIG overhaul [5] series.
Unfortunately, story repeats itself - problems are found within the core
of a driver. Painting it with different colors does not change the fact
that is it still a house of cards. As changes needed to address those
issues would make Skylake solution incompatible with its previous
revisions, a decision has been made to provide a new solution instead.
In time it would deprecate and replace Skylake-driver.
That solution has been called AVS - from AudioDSP architecture name:
Audio-Voice-Speech. It is meant to provide support for the exact same
range of platforms as its predecessor: SKL, KBL, AML and APL.

ALSA/ASoC/SOF/Intel: improve support for ES8336-based platforms
Merge series from Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>:
This patchset adds a number of improvements for ES8336-based Intel
platforms, which are not well supported at all in Linux. Since
Christmas 2021, we've seen dozens of reports of broken audio [1].
The fundamental problem is that those platforms were built for Windows
but using an I2S codec - instead of the HDaudio traditional
solution. As a result, we are missing all the usual information needed
to configure the audio card (which I2S, what configuration, DMICs or
not, etc). The situation is similar to Baytrail with all possible
permutations enabled.
Some of the information can be discovered by checking the contents of
the 'NHLT' ACPI table. This helps discover at run-time which SSP to
use, and the number of microphones present. This NHLT-based solution
helps remove quirks that were added earlier.
Unfortunately, there are still a number of platform properties that
are not described by ACPI, just as GPIOs used for speakers, jack
detection inversion, etc. For some case, quirks are still provided in
the machine drivers.
Additional work will likely be needed, e.g. to detect which MCLK needs
to be used, refine the UCM settings, add the ES8326 codec driver, but
this is a first-step towards an 'out of the box' experience on Intel
platforms.

be merged in the ASoC tree.

Different topology filenames may be required depending on which SSP is
used, and whether or not digital mics are present.
This patch adds a tplg_quirk_mask and in the case of the SOF driver
adds the relevant configurations.
This is a short-term solution to the ES8336 support issues.
In a long-term solution, we would need an interface where the machine
driver or platform driver have the ability to alter the topology
hard-coded low-level hardware support, e.g. by substituting an
interface for another, or disabling an interface that is not supported
on a given skew.
ASoC: SOF: Intel: hda: report SSP link mask to machine driver
For devices designed for Windows, the SSP information should be listed
in the NHLT, and when present can be used to set quirks automatically
in the machine driver.
The NHLT information exposes BT and analog audio connections
separately, for now we are only interested in the analog audio parts.
The use of dev_info() for the SSP mask is intentional so that we can
immediately flag devices with an ES8336 codec. Since NHLT is not used
for recent Chromebooks these messages should be rare.
ALSA: intel-nhlt: add helper to detect SSP link mask
The NHLT information can be used to figure out which SSPs are enabled
in a platform.
The 'SSP' link type is too broad for machine drivers, since it can
cover the Bluetooth sideband and the analog audio codec connections,
so this helper exposes a parameter to filter with the device
type (DEVICE_I2S refers to analog audio codec in NHLT parlance).
The helper returns a mask, since more than one SSP may be used for
analog audio, e.g. the NHLT spec describes the use of SSP0 for
amplifiers and SSP1 for headset codec. Note that if more than one bit
is set, it's impossible to determine which SSP is connected to what
external component. Additional platform-specific information based on
e.g. DMI quirks would still be required in the machine driver to
configure the relevant dailinks.

ASoC: SOF: Intel: hda: retrieve DMIC number for I2S boards
We currently extract the DMIC number only for HDaudio or SoundWire
platforms. For I2S/TDM platforms, this wasn't necessary until now, but
with devices with ES8336 we need to find a solution to detect dmics
more reliably than with a DMI quirk.
ASoC: soc-acpi: add information on I2S/TDM link mask
The platform driver may have information on which I2S/TDM link(s) to
enable in the machine driver. In the case of Intel devices, this may
be extracted from NHLT tables in platform firmware. This link
information is necessary to make sure machine driver and topology are
aligned.
Remove the comp_dai and dai_config members of struct snd_sof_dai and
replace it with a void *private field. Introduce a new struct
sof_dai_private_data that will contain the pointer to these two fields.
The topology parser will populate this structure and save it as part of
the "private" member in snd_sof_dai. Change all users of these fields to
use the private member instead.

ASoC: SOF: Add a tuples array to struct snd_sof_widget
Add 2 new fields to snd_sof_widget to store an array of tuples
defined by struct snd_sof_tuple and the number of tuples. When the
topology gets parsed, the tuples associated with a widget will be stored
in this array and will be used to construct the IPC structure
depending on the IPC version.

Clean ups and preparation for IPC abstraction in the SOF driver
Merge series from Ranjani Sridharan <ranjani.sridharan@linux.intel.com>:
In preparation for adding support for the new IPC version that has been
introduced in the SOF firmware, this patch set includes some clean ups
and necessary modifications to commonly used functions that will be
re-used across different IPC-specific code.

Add driver for SAMA7G5's PDMC
Merge series from Codrin Ciubotariu <codrin.ciubotariu@microchip.com>:
This patch series adds support for Pulse Density Microphone Controller
(PDMC), present on Microchip's SAMA7G5.
The PDMC interfaces up to 4 digital microphones having Pulse Density
Modulated (PDM) outputs. It generates a single clock line and samples 1 or
2 data lines. The signal path includes an audio grade programmable
decimation filter and outputs 24-bit audio words.
The source of each channel can be independently defined as PDMC_DS0 or
PDMC_DS1, sampled at the rising or falling edge of PDMC_CLK.
The patch series starts with a fix on the ASoC DMA engine support. Then
continues with the bindings and the driver of PDMC. It is followed by the
DT nodes for SAMA7G5 and SAMA7G5-EK. In the end, the drivers for PDMC
and PDM microphones are enabled in sama7_defconfig.

ASoC: mxs: Fix error handling in mxs_sgtl5000_probe
This function only calls of_node_put() in the regular path.
And it will cause refcount leak in error paths.
For example, when codec_np is NULL, saif_np[0] and saif_np[1]
are not NULL, it will cause leaks.
of_node_put() will check if the node pointer is NULL, so we can
call it directly to release the refcount of regular pointers.
