Merge series from Elinor Montmasson <elinor.montmasson@savoirfairelinux.com>:

This is a series of patches aiming to make the machine driver
`fsl-asoc-card` compatible with S/PDIF controllers on imx boards.  The
main goal is to allow the use of S/PDIF controllers with ASRC modules.

The `imx-spdif` machine driver already has specific support for S/PDIF
controllers but doesn't support using an ASRC with it. However, the
`fsl-asoc-card` machine driver has the necessary code to create a sound
card which can use an ASRC module.
It is then possible to extend the support for S/PDIF audio cards by
merging the `imx-spdif` driver into `fsl-asoc-card`.

The first three patches adapt the `fsl-asoc-card` driver to support
multiple codec use cases.
The driver can get 2 codec phandles from the device tree, and
codec-related variables are doubled.
`for_each_codecs` macros are also used when possible to ease adding
other multi-codec use cases in the future.
It makes possible to use the two S/PDIF dummy codec drivers
`spdif_receiver` and `spdif_transmitter` instead of `snd-soc-dummy`,
which was used in `imx-spdif`.

The fourth patch merges the S/PDIF support from `imx-spdif` to
`fsl-asoc-card`.
`fsl-asoc-card` offers the same functionalities as `imx-spdif` did, but
this merge also extends the S/PDIF support with the possibility of using
an ASRC.
Compatible "fsl,imx-audio-spdif" is kept, but `fsl-asoc-card` uses
different DT properties compared to `imx-spdif`:
* The "spdif-controller" property from `imx-spdif` is named "audio-cpu"
  in `fsl-asoc-card`.
* `fsl-asoc-card` uses codecs explicitly declared in DT with
  "audio-codec". With an S/PDIF, codec drivers `spdif_transmitter` and
  `spdif_receiver` should be used. Driver `imx-spdif` used instead the
  dummy codec and a pair of boolean properties, "spdif-in" and
  "spdif-out".
Backward compatibility is therefore implemented in `fsl-asoc-card`.
However, it is recommended to use the new properties when needed.
Especially, declaring and using S/PDIF transmitter and/or receiver nodes
is better than using the dummy codec.

The last three patches update the device tree bindings of
`fsl-asoc-card` and update all in-tree device trees to use the
`fsl-asoc-card` properties.
Note that as the old properties are still supported:
* previous versions of in-tree device trees are still supported.
* out-of-tree device trees are still supported.

This series of patches was successfully built for arm64 and x86 on top
of the latest "for-next" branch of the ASoC git tree on the 26th of June
2024.
These modifications have also been tested on an i.MX8MN evaluation board
with a linux kernel RT v6.1.26-rt8.

Merge series from Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>:

Allocate the memory with scoped/cleanup.h to reduce error handling
(simpler error paths) and make the code a bit smaller.

The S/PDIF audio card support with compatible "fsl,imx-audio-spdif"
was merged from imx-spdif into the fsl-asoc-card driver.
It makes possible to use an S/PDIF with an ASRC.

This merge introduces new DT bindings to use with compatible
"fsl,imx-audio-spdif" to follow the way fsl-asoc-card works:
* the "spdif-controller" property from imx-spdif is named "audio-cpu"
  in fsl-asoc-card.
* fsl-asoc-card uses codecs explicitly declared in DT
  with "audio-codec".
  With an SPDIF, codec drivers spdif_transmitter and
  spdif_receiver should be used.
  Driver imx-spdif used instead the dummy codec and a pair of
  boolean properties, "spdif-in" and "spdif-out".

In an upcoming commit, in-tree DTs will be modified to follow these new
properties:
* Property "spdif-controller" will be renamed "audio-cpu".
* spdif_transmitter and spdif_receiver nodes will be declared
  and linked to the fsl-asoc-card node with the property "audio-codec".

To keep backward compatibility with other DTs, support for
"spdif-controller", "spdif-in" and "spdif-out" properties is kept.
However, it is recommended to use the new properties if possible.
It is better to declare transmitter and/or receiver
in DT than using the dummy codec.

DTs using compatible "fsl,imx-audio-spdif" are still supported, and
fsl-asoc-card will behave the same as imx-spdif for these DTs.

Merge series from Herve Codina <herve.codina@bootlin.com>:

The qmc_audio driver supports only audio in interleaved mode.
Non-interleaved mode can be easily supported using several QMC channel
per DAI. In that case, data related to ch0 are sent to (received from)
the first QMC channel, data related to ch1 use the next QMC channel and
so on up to the last channel.

In terms of constraints and settings, the interleaved and
non-interleaved modes are slightly different.

In interleaved mode:
  - The sample size should fit in the number of time-slots available for
    the QMC channel.
  - The number of audio channels should fit in the number of time-slots
    (taking into account the sample size) available for the QMC channel.

In non-interleaved mode:
  - The number of audio channels is the number of available QMC
    channels.
  - Each QMC channel should have the same number of time-slots.
  - The sample size equals the number of time-slots of one QMC channel.

This series add support for the non-interleaved mode in the qmc_audio
driver and is composed of the following parts:
  - Patches 1 and 2: Fix some issues in the qmc_audio
  - Patches 3 to 6: Prepare qmc_audio for the non-interleaved mode
  - Patches 7 and 8: Extend the QMC driver API
  - Patches 9 and 10: The support for non-interleaved mode itself

The current fsl_qmc_audio works in interleaved mode. The audio samples
are interleaved and all data are sent to (received from) one QMC
channel.

Using several QMC channels, non interleaved mode can be easily
supported. In that case, data related to ch0 are sent to (received from)
the first QMC channel, data related to ch1 use the next QMC channel and
so on up to the last channel.

In terms of constraints and settings, the two modes are slightly
different:
- Interleaved mode:
    - The sample size should fit in the number of time-slots available
      for the QMC channel.
    - The number of audio channels should fit in the number of
      time-slots (taking into account the sample size) available for the
      QMC channel.
- Non-interleaved mode:
    - The number of audio channels is the number of available QMC
      channels.
    - Each QMC channel should have the same number of time-slots.
    - The sample size equals the number of time-slots of one QMC
      channel.

per DAI. The DAI switches in non-interleaved mode when more that one QMC
channel is available.

The current QMC audio driver uses only one QMC channel per DAI. The
context used by QMC channel transfer (read and write) completion
routines does not contains any QMC channel and the only one available
per DAI is used to schedule the next transfer.
This works pretty well with only one QMC channel per DAI.

The future support for non-inlerleave mode will use several QMC channel
per DAI. In that case, QMC channel transfer completion routines need to
identify the QMC channel related to the completion.

In order to fill this lack, even if identifying the current QMC channel
among several QMC channels is not needed for the current code, add one
indirection level and introduce the qmc_dai_chan data structrure.
This structure contains the QMC channel involved in the completion and
refererences to the runtime context (capture and playback) used by the

The driver mixes some internal values for channel DMA buffer handling
and PCM pointer handling. In the currently supported interleaved mode,
this mix does not lead to any issues but in order to prepare the
support for the non-interleaved mode, having them clearly separated will
ease the support and avoid additional computation to convert values used
in channel DMA buffer management in values usable for PCM pointer.
