ebbb165d2c ASoC: Intel: Unify the thinkpad10 and aegex10 byt-match quirks
There is no reason to have separate quirk-handlers / byt_machine_id-s
for these.

These are both cases of BYT devices with a 10EC5640 ACPI HID while using
a rt5672 codec.

The Dell Venue 10 Pro 5055 is another example of such a device, instead
of adding a third byt_machine_id definition for this Dell model, make
change the 2 existing cases into a generic BYT_RT5672 byt_machine_id
in preparation for adding a quirk for the Dell Venue 10 Pro 5055.

52cad756b7 ASoC: intel, keembay-i2s: Fix a dt_binding_check warning
The property "dmas" contains two items: DMA "TX" and "RX" channel,
Therefore, its value also needs to be written in two parts.

Otherwise, below YAML check warning is reported:
Documentation/devicetree/bindings/sound/intel,keembay-i2s.example.dt.yaml:\
i2s@20140000: dmas: [[4294967295, 29, 4294967295, 33]] is too short

df421a3a6f Merge series "ASoC: remove cppchecks warnings on lm49453 and da732x" from Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>:
There are the last two patches in the cleanups, this time I am not
sure what the code does and what the proper fix might be. Feedback
welcome.

75c324d5ab Merge series "ASoC: dt-bindings: Rework audio-graph-port schema" from Rob Herring <robh@kernel.org>:
This series refactors the audio-graph-port.yaml schema moving the
'port' node out of the schema and updating to use graph.yaml schema.
This allows users to define what each 'port' node is like other graph
binding users.

v2:
- Rebase on ASoC tree

Hi Mark

These are small clanup patches for soc-core.
[1/2] patch adds missing explanation, and
[2/2] patch fixup error handling of rtd.

Kuninori Morimoto (2):
  ASoC: soc-core: add comment for rtd freeing
  ASoC: soc-core: use device_unregister() if rtd allocation failed

Trivial cleanups to make cppcheck less verbose.

There should be no functionality change, except for the 'sti_uniperif'
patch where an error check was added.

Keeping two separate tests was probably intentional for clarity, but
since this generates warnings we might as well make cppcheck happy so
that we have fewer warnings.

ad858508fd Merge tag 'mute-led-rework' of https://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound into asoc-5.13
ALSA: control - add generic LED API

This patchset tries to resolve the diversity in the audio LED
control among the ALSA drivers. A new control layer registration
is introduced which allows to run additional operations on
top of the elementary ALSA sound controls.

A new control access group (three bits in the access flags)
was introduced to carry the LED group information for
the sound controls. The low-level sound drivers can just
mark those controls using this access group. This information
is not exported to the user space, but user space can
manage the LED sound control associations through sysfs
(last patch) per Mark's request. It makes things fully
configurable in the kernel and user space (UCM).

The actual state ('route') evaluation is really easy
(the minimal value check for all channels / controls / cards).
If there's more complicated logic for a given hardware,
the card driver may eventually export a new read-only
sound control for the LED group and do the logic itself.

The new LED trigger control code is completely separated
and possibly optional (there's no symbol dependency).
The full code separation allows eventually to move this
LED trigger control to the user space in future.
Actually it replaces the already present functionality
in the kernel space (HDA drivers) and allows a quick adoption
for the recent hardware (ASoC codecs including SoundWire).

snd_ctl_led            24576  0

The sound driver implementation is really easy:

1) call snd_ctl_led_request() when control LED layer should be
   automatically activated
   / it calls module_request("snd-ctl-led") on demand /
2) mark all related kcontrols with
        SNDRV_CTL_ELEM_ACCESS_SPK_LED or
        SNDRV_CTL_ELEM_ACCESS_MIC_LED

326b0037fd Merge series "ASoC: simple-card: cleanup and prepare for Multi CPU/Codec support" from Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>:
Hi Mark

I want to add new audio-graph-card2 driver which can support
not only DPCM, but also Multi-CPU/Codec, and Codec2Codec.
And it is also supporting user customization.

But before supporting such driver, we need to cleanup existing
simple-card / audio-graph, because these and new driver are
sharing code.

This patch-set are cleanup and prepare for Multi-CPU/Codec support.

The SoC sound core will generate a driver name by normalizing the card

the driver and is therefore useless for this purpose.

Make the driver name more useful by setting it explicitly during card

jack-detect connected to JD2_IN4N, instead of using the default
IN3 for its internal mic and JD1_IN4P for jack-detect.

It also only has 1 speaker.

Add a quirk applying the correct settings for this configuration.

39af7f7a03 ASoC: simple-card: cleanup graph_for_each_link()
simple-card checks DT links 2 times. 1st is for counting DAIs / links
to allocating memory, 2nd is for detecting DAIs.
To detecting DAIs as CPU-dummy -> dummy-Codec order when DPCM case,
it uses  loops 2 times.
Because of this kind of complex background, it needs to use local
varuable for it, and each call-back functions need to care about it.

Now, 1st and 2nd DT link check are using same order,
thus we can share same code. This patch do it.

To detecting DAIs as CPU-dummy -> dummy-Codec order when DPCM case,
it uses loops 2 times at 2nd DT link check.
But it doesn't do it at 1st DT link check.

	for (li.cpu = 1; li.cpu >= 0; li.cpu--) {
		/*

		 * To avoid random sub-device numbering,
		 * detect "dummy-Codec" in last;
		 */
		ret = simple_for_each_link(...);
		...
	}

To prepare supporting multi-CPU/Codec, and code cleanup,
this patch use same loop for 1st DT link check, too.

050c7950fd ASoC: simple-card-utils: alloc dai_link information for CPU/Codec/Platform
simple-card / audio-graph are assuming single CPU/Codec/Platform on
dai_link. Because of it, it is difficult to support Multi-CPU/Codec.

This patch allocs CPU/Codec/Platform dai_link imformation
instead of using existing props information. It can update to
multi-CPU/Codec, but is still assuming single-CPU/Codec for now.

The nvidia,tegra210-ahub binding is missing schema for child nodes. This
results in warnings if 'additionalProperties: false' is set (or when the

and reference their schema if one exists.

a135dfb5de ALSA: led control - add sysfs kcontrol LED marking layer
We need to manage the kcontrol entries association for the LED trigger
from the user space. This patch adds a layer to the sysfs tree like:

/sys/devices/virtual/sound/ctl-led/mic
   + card0
   |  + attach
   |  + detach
   |  ...
   + card1
      + attach
      ...

Operations:

  attach and detach
    - amixer style ID is accepted and easy strings for numid and
      simple names
  reset
    - reset all associated kcontrol entries
  list
    - list associated kcontrol entries (numid values only)

Additional symlinks:

/sys/devices/virtual/sound/ctl-led/mic/card0/card ->
  /sys/class/sound/card0

/sys/class/sound/card0/controlC0/led-mic ->
  /sys/devices/virtual/sound/ctl-led/mic/card0

cb17fe0045 ALSA: control - add sysfs support to the LED trigger module
Create SYSFS/devices/virtual/sound/ctl-led tree
(with SYSFS/class/sound/ctl-led symlink).

  speaker/
    +-- mode
    +-- brightness
  mic/
    +-- mode
    +-- brightness

Copy the idea from the HDA driver and allow to set the audio
LEDs based on the various modes:

- follow mute
- follow moute (inverted to follow mute)
- off
- on

Also, the actual LED state is exposed.
