ASoC: rt5670: Add a rt5670_components() helper
The rt5670 codec driver uses DMI quirks to configure the DMIC data-pins,
which means that it knows which DMIC interface is used on a specific
device.

ATM we duplicate this DMI matching inside the UCM profiles to select
the right DMIC interface. Add a rt5670_components() helper which the
machine-driver can use to set the components string of the card so
that UCM can get the info from the components string.

This way we only need to add new DMI quirks in one place.

ASoC: Intel: cht_bsw_rt5672: Add support for Bay Trail CR / SSP0
The rt5672 codec is used on some Bay Trail CR boards, on these SoCs SSP2
is not available and SSP0 should be used instead. At support for this.

This has been tested on a Dell Venue 10 Pro 5055.

ASoC: Intel: Baytrail: Add quirk for the Dell Venue 10 Pro 5055 tablet
The Dell Venue 10 Pro 5055 tablet uses an ACPI HID of 10EC5640 while using
a rt5672 codec (instead of a rt5640 codec). Add a quirk for this.

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.

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 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

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.

ASoC: tegra: Set driver name explicitly
The SoC sound core will generate a driver name by normalizing the card
name. However, most of the time that name does not tell anything about
the driver and is therefore useless for this purpose.

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

ASoC: Intel: bytcr_rt5640: Add quirk for the Chuwi Hi8 tablet
The Chuwi Hi8 tablet is using an analog mic on IN1 and has its
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.

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.

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.

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

  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.

e65bf99718 ALSA: HDA - remove the custom implementation for the audio LED trigger
With the new snd-ctl-led module, we have a generic way
to trigger audio LEDs based on the sound control changes.

Remove the custom implementation from the HDA driver.

Move the LED initialization before snd_hda_gen_parse_auto_config()
call in all drivers to create marked controls there.

22d8de62f1 ALSA: control - add generic LED trigger module as the new control layer
The recent laptops have usually two LEDs assigned to reflect
the speaker and microphone mute state. This implementation
adds a tiny layer on top of the control API which calculates
the state for those LEDs using the driver callbacks.

Two new access flags are introduced to describe the controls
which affects the audio path settings (an easy code change
for drivers).

The LED resource can be shared with multiple sound cards with
this code. The user space controls may be added to the state
chain on demand, too.

This code should replace the LED code in the HDA driver and
add a possibility to easy extend the other drivers (ASoC
codecs etc.).
