There are no users left and new users should rather use the component_driver

instead of

	.dapm_widgets = ...,
	.num_dapm_widgets = ...,

86dbf2ac6f ASoC: Add support for automatically going to BIAS_OFF on suspend
There is a substantial amount of drivers that in go to SND_SOC_BIAS_OFF on
suspend and go back to SND_SOC_BIAS_SUSPEND on resume (Often this is even
the only thing done in the suspend and resume handlers). This patch
introduces a new suspend_bias_off flag, which when set by a driver will let
the ASoC core automatically put the device's DAPM context at the
SND_SOC_BIAS_OFF level during suspend. Once the device is resumed the DAPM
context will go back to SND_SOC_BIAS_STANDBY (if the context is idle,
otherwise to SND_SOC_BIAS_ON).

This will allow us to remove a fair bit of duplicated code from the drivers.

7af142f752 ALSA: pcm: Uninline snd_pcm_stream_lock() and _unlock()
The previous commit for the non-atomic PCM ops added more codes to
snd_pcm_stream_lock() and its variants.  Since they are inlined
functions, it resulted in a significant code size bloat.  For reducing
the size bloat, this patch changes the inline functions to the normal
function calls.  The export of rwlock and rwsem are removed as well,
since they are referred only in pcm_native.c now.

257f8cce5d ALSA: pcm: Allow nonatomic trigger operations
Currently, many PCM operations are performed in a critical section
protected by spinlock, typically the trigger and pointer callbacks are
assumed to be atomic.  This is basically because some trigger action
(e.g. PCM stop after drain or xrun) is done in the interrupt handler.
If a driver runs in a threaded irq, however, this doesn't have to be
atomic.  And many devices want to handle trigger in a non-atomic
context due to lengthy communications.

This patch tries all PCM calls operational in non-atomic context.
What it does is very simple: replaces the substream spinlock with the
corresponding substream mutex when pcm->nonatomic flag is set.  The
driver that wants to use the non-atomic PCM ops just needs to set the
flag and keep the rest as is.  (Of course, it must not handle any PCM
ops in irq context.)

Note that the code doesn't check whether it's atomic-safe or not, but
trust in 100% that the driver sets pcm->nonatomic correctly.

One possible problem is the case where linked PCM substreams have
inconsistent nonatomic states.  For avoiding this, snd_pcm_link()
returns an error if one tries to link an inconsistent PCM substream.

f1d45cc3ae ASoC: Consolidate platform and CODEC probe/remove
The platform and CODEC probe and remove code is now largely identical. This
patch consolidates it at the component level.

The resulting code is slightly larger due to all the boiler plate code setting
up the indirection for the table based control and DAPM registration.  Once all
drivers have been update to no longer use the snd_soc_codec_driver and
snd_soc_platform_driver specific fields for this the indirection can be removed
again.

This patch contains two noteworthy hacks that are only meant to be temporary to
be able to update drivers and the core in separate incremental patches.

The first hack is related to that some DPCM platforms expect that the DAPM
widgets for the DAIs of a snd_soc_component are created in the DAPM context of
the snd_soc_platform that has the same parent device. For handling this the
steal_sibling_dai_widgets attribute is introduced. It gets set for
snd_soc_platforms that register DAPM elements. When creating the DAI widgets for
a component this flag is checked and if it is found on one of the siblings the
component will not create any DAI widgets in its own DAPM context. If the
attribute is set on a platform it will look for siblings components and create
DAI widgets for them in its own context. The fix for this will be to update
the offending drivers to only register a single component rather than two.

The second hack deals with the fact that the ASoC card suspend and resume code
still needs a list of CODECs that have been registered for the card. To handle
this the generic probe and remove path have a check to see if the component is
CODEC and if yes add/remove it to the card's CODEC list. While it is possible to
clean up the suspend/resume code to not need the CODEC list anymore this is a
bit of a chicken and egg problem since it will become easier to clean up the
suspend/resume code once there is a unified component layer.

81c7cfd1b2 ASoC: Move debugfs registration to the component level
The debugfs registration is mostly identical between platforms and CODECs. This
patches consolidates the two implementations at the component level.

Unfortunately there are still a couple of CODEC specific debugfs files that are
related to legacy ASoC IO that need to be registered. For this a new callback is
added to the component struct that will be initialized when a CODEC is
registered and will be used to register the CODEC specific files. Once there are
no drivers left using legacy IO this can be removed again.

d7821953cf ASoC: wm8962: Let CODEC driver enable and disable its own MCLK
snd_soc_open() will trigger pm_runtime resume() which will then enable
the regulator and initialization. So we should make sure the MCLK is
enabled before this resume().

Previously we let the machine driver get the clock and enable it in
its probe(). However, considering about power saving, it'll be better
to enable it when it's going to be used and disable it after using.

So this patch just simply adds clk_get() and clk_enable() to WM8962
driver. Meanwhile, it marks clock pointer to NULL if no clock assigned
to it so it will not break any current function.

0f2780ad4c ASoC: Add function to register component controls
We have now everything in place to actual let a component register controls. Add
a function which allows to do so.

Also update snd_soc_add_codec_controls() and snd_soc_platform_controls() to use
this new function internally. And while we are at it also change the
num_controls parameter of those two functions from int to unsigned int.

00200107a2 ASoC: Move card field form platform/codec to component
Both the snd_soc_codec and snd_soc_platform struct do have a pointer to the
parent card and both handle this pointer in mostly the same way. This patch
moves the card field to the component level which will allow further code
consolidation between platforms and CODECS.

Since there are only a handful of users of the snd_soc_codec struct's card field
(and none of the snd_soc_platform's) these are update in this patch as well,
which allows it to be removed from the snd_soc_codec struct.

88bd870f02 ASoC: core: Add initial support for DAI multicodec
DAI link assumes a one to one mapping between CPU DAI and CODEC. In
some cases, the same CPU DAI can be connected to several codecs.
This is the case for example, if you connect two mono codecs to the
same I2S link in order to have a stereo card.
The current ASoC implementation does not allow such setup.

Add support for DAI links composed of a single CPU DAI and multiple
CODECs. Sound cards have to pass the CODECs array in the corresponding
DAI link through a new 'snd_soc_dai_link_component' struct. Each CODEC in
this array is described in the same manner single CODEC DAIs are
(either DT/OF node or codec_name).

Multi-codec links are not supported in the case of CODEC to CODEC links.
Just print a warning if it happens.

Based on an original code done by Misael.
