Currently for the PCM and mixer tests we report test names which identify
the card being tested with the card number. This ensures we have unique
names but since card numbers are dynamically assigned at runtime the names
we end up with will often not be stable on systems with multiple cards
especially where those cards are provided by separate modules loeaded at
runtime. This makes it difficult for automated systems and UIs to relate
test results between runs on affected platforms.
Address this by replacing our use of card numbers with card names which are
more likely to be stable across runs. We use the card ID since it is
guaranteed to be unique by default, unlike the long name. There is still
some vulnerability to ordering issues if multiple cards with the same base
ID are present in the system but have separate dependencies but not all
drivers put distinguishing information in their long names.

When the UMP Endpoint is configured with static blocks, the block
configuration will never change, hence the unused ports will be
unchanged as well. Creating sequencer ports for those unused ports
is simply useless, and it might be rather confusing for users.
The idea behind the inactive ports was for allowing connections
from/to ports that can become usable later, but this will never
happen for inactive groups in static blocks.
Let's change the sequencer UMP binding to skip those unused ports when
the UMP EP is with static blocks.

ASoC: Updates for for v6.11
There are a lot of changes in here, though the big bulk of things is
cleanups and simplifications of various kinds which are internally
rather than externally visible. A good chunk of those are DT schema
conversions, but there's also a lot of changes in the code.
Highlights:
- Syncing of features between simple-audio-card and the two
audio-graph cards so there is no reason to stick with an older
driver.
- Support for specifying the order of operations for components within
cards to allow quirking for unusual systems.
- New support for Asahi Kasei AK4619, Cirrus Logic CS530x, Everest
Semiconductors ES8311, NXP i.MX95 and LPC32xx, Qualcomm LPASS v2.5
and WCD937x, Realtek RT1318 and RT1320 and Texas Instruments PCM5242.

A malformed USB descriptor may pass the lengthy mixer description with

This patch introduces a sanity check of the number of channels to bail
out the parsing when too many channels are found.

Change the log message of the wmfw format version to include
the file name, and change the message to say "format" instead
of "Firmware version". Merge this with the message that logs
the timestamp.
The wmfw format version is information that is useful to have
logged because the behaviour of firmware controls depends on
the wmfw format. So "unexpected" behaviour could be caused by
having expectations based on one format of wmfw when a
different format has been loaded.
But the original message was confusing. It reported the file
format version but didn't actually log the name of the file it
referred to. It also called it "Firmware version", which is
confusing when a later message also logs a firmware version
that is the version of the actual firmware within the wmfw.
The logging of the firmware timestamp has been merged into this.
That was originally a dbg-only message, but as we are already
logging a line of info, we might as well add a few extra
characters to log the timestamp. The timestamp is now logged
in hexadecimal - it's not particularly useful as a decimal
value.

Don't allocate a temporary buffer to hold a NUL-terminated copy
of the NAME/INFO string from the wmfw/bin. It can be printed
directly to the log. Also limit the maximum number of characters
that will be logged from this string.
The NAME/INFO blocks in the firmware files are an array of
characters with a length, not a NUL-terminated C string. The
original code allocated a temporary buffer to make a
NUL-terminated copy of the string and then passed that to
dev_info(). There's no need for this: printf formatting can
use "%.*s" to print a character array of a given length.

Merge series from Elinor Montmasson <[email protected]>:
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.

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.

The imx-spdif machine driver creates audio card to directly use an
S/PDIF device. However, it doesn't support interacting with an ASRC.
fsl-asoc-card already has the support to create audio card which can
use the ASRC.
Merge the S/PDIF support from imx-spdif into driver fsl-asoc-card
to extend the support of S/PDIF audio card with the use of ASRC devices.
fsl-asoc-card uses slightly different DT properties than imx-spdif:

Use strnlen() instead of strlen() on the algorithm and coefficient name
string arrays in V1 wmfw files.
In V1 wmfw files the name is a NUL-terminated string in a fixed-size
array. cs_dsp should protect against overrunning the array if the NUL
terminator is missing.
