c5599b87a8 ASoC: Replace list_empty(&card->codec_dev_list) with !card->instantiated
With componentization we no longer necessarily need a snd_soc_codec struct for a
card. Instead of checking if the card's CODEC list is empty just use
card->instantiated to check if the card has been instantiated yet.

886f569225 ASoC: Automatically initialize regmap for all components
So far regmap is only automatically initialized for CODECs. Now that we have the
infrastructure in place to let components have DAPM widgets and controls that
want to use the generic regmap based IO also make sure to automatically
initialize regmap for all components.

14621c7e5e ASoC: Consolidate CPU and CODEC DAI lookup
The lookup of CPU and CODEC DAIs is fairly similar and can easily be
consolidated into a single helper function.

There are two main differences in the current implementation of the CPU and
CODEC DAI lookup:
 1) CPU DAIs can be looked up by the DAI name alone and do not necessarily
   require a component name/of_node.
 2) The CODEC DAI search only considers DAIs from CODEC components.

For 1) the new helper function will allow to lookup DAIs without providing a
component name or of_node, but since snd_soc_register_card() already rejects
CODEC DAI link components without neither a of_node or a name we'll never get
into the situation where we try to lookup a CODEC DAI without a name/of_node.
For 2) the new helper function just always considers all components.
Componentization is now at a point where it is possible to register a CODEC as a
snd_soc_component rather than a snd_soc_codec, by considering DAIs from all
components it is possible to use such a CODEC in a DAI link.

ffbd7dd72b ASoC: Cleanup DAI module reference counting
Currently when a DAI has no CODEC associated to it the reference on the module
containing the DAI driver is increased when the DAI is probed and decrease when
the DAI is removed. For DAIs with CODECs the module reference count was already
incremented when the CODEC is probed. Now that all components have their module
reference count incremented when they are probed and all DAIs do have a
component it is possible to remove the module reference counting on DAI probe
and removal.

70090bbb8b ASoC: Move component->probed check into soc_{remove,probe}_component()
Having the check in a centralized place makes the code a bit cleaner and
shorter.

Note: There is a slight semantic change in this patch. soc_probe_aux_dev() will
no longer return -EBUSY if the AUX dev has already been probed before. This is
fine though since it will simply do nothing in that case and return success.

This patch makes it possible to register arbitrary components as a AUX dev
for a card. This was previously only possible for CODEC components. With
componentization having made it possible for components to have DAPM contexts
and controls there is no reason why AUX devs should be artificially limited to
snd_soc_codec devices.

61aca5646b ASoC: Add component level probe/remove support
Now that we have a unified probe and remove path make sure to call them for all
components. soc_{probe,remove}_component are responsible for setting up the DAPM
context for the component, initialize the component prefix, manage the debugfs
entries as well as do the registration of table based controls and DAPM
elements. They also call the component drivers probe and remove callbacks. This
patch makes these things available for generic snd_soc_component drivers rather
than only having them for snd_soc_codec and snd_soc_platform drivers.

93c3ce76cc ASoC: Make rtd->codec optional
There are some place in the ASoC core that expect rtd->codec to be non NULL
(mainly CODEC specific sysfs files). With componentization going forward
rtd->codec might be NULL in some cases. This patch prepares the core for this by
not registering CODEC specific sysfs files if rtd->codec is NULL. sysfs file
removal does not need to be conditionalized as it handles the removal of
non-existing files just fine.

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.

6391fffb7b ASoC: ab8500-codec: Drop bank prefix from AB8500_GPIO_DIR4_REG register define
The AB8500_GPIO_DIR4_REG register define has the bank for the register in the
upper 8 bits and the register itself in the lower 8 bits. When passing it to
abx500_{set,get}_register_interruptible() the upper bits get truncated which
generates the following warning from sparse:
	sound/soc/codecs/ab8500-codec.c:1972:53: warning: cast truncates bits
	 from constant value (1013 becomes 13)
	sound/soc/codecs/ab8500-codec.c:1980:53: warning: cast truncates bits
	 from constant value (1013 becomes 13)

The bank is passed separately to abx500_{set,get}_register_interruptible() so
the code works fine as it is. Given that all users of AB8500_GPIO_DIR4_REG
always truncate the upper 8 bits just remove them from the define.

Also remove the unnecessary casts to u8.

There is one design rule according to SAI's reference manual:
If the transmitter bit clock and frame sync are to be used by both transmitter

and the receiver for synchronous operation.

And SYNC of TCR2 is a 2-width control bit:
00 Asynchronous mode.
01 Synchronous with receiver.
10 Synchronous with another SAI transmitter.
11 Synchronous with another SAI receiver.

So the driver should have set SYNC bit of TCR2 to 0x0, and meanwhile set SYNC
bit of RCR2 to 0x1 (Synchronous with transmitter).

ce7344a4eb ASoC: fsl_sai: Make Synchronous and Asynchronous modes exclusive
The previous patch (ASoC: fsl_sai: Add asynchronous mode support) added
new Device Tree bindings for Asynchronous and Synchronous modes support.
However, these two shall not be present at the same time.

So this patch just simply makes them exclusive so as to avoid incorrect
Device Tree binding usage.

08fdf65e37 ASoC: fsl_sai: Add asynchronous mode support
SAI supports these operation modes:
1) asynchronous mode
   Both Tx and Rx are set to be asynchronous.
2) synchronous mode (Rx sync with Tx)
   Tx is set to be asynchronous, Rx is set to be synchronous.
3) synchronous mode (Tx sync with Rx)
   Rx is set to be asynchronous, Tx is set to be synchronous.
4) synchronous mode (Tx/Rx sync with another SAI's Tx)
5) synchronous mode (Tx/Rx sync with another SAI's Rx)

* 4) and 5) are beyond this patch because they are related with another SAI.

As the initial version of this SAI driver, it supported 2) as default while
the others were totally missing.

So this patch just adds supports for 1) and 3).

af96ff5b74 ASoC: fsl_sai: Set SYNC bit of TCR2 to Asynchronous Mode
There is one design rule according to SAI's reference manual:
If the transmitter bit clock and frame sync are to be used by both transmitter
and receiver, the transmitter must be configured for asynchronous operation
and the receiver for synchronous operation.

And SYNC of TCR2 is a 2-width control bit:
00 Asynchronous mode.
01 Synchronous with receiver.
10 Synchronous with another SAI transmitter.
11 Synchronous with another SAI receiver.

So the driver should have set SYNC bit of TCR2 to 0x0, and meanwhile set SYNC
bit of RCR2 to 0x1 (Synchronous with transmitter).

Original driver didn't store the number of slots, just fix the slot number
to 2, use this default number to calculate bclk and pins for TX/RX.
In this patch, add one parameter for slots, and update the calculation of
bclk and pins of TX/RX. Then driver will be compatible with slots > 2 in
TDM mode.

708b4351f0 ASoC: fsl: Add Freescale Generic ASoC Sound Card with ASRC support
The Freescale Generic ASoC Sound Card is a general ASoC DAI Link driver that
can be used, ideally, for all Freescale CPU DAI drivers and external CODECs.

The idea of this generic sound card is a bit like ASoC Simple Card. However,
for Freescale SoCs (especially those released in recent years), most of them
have ASRC (Documentation/devicetree/bindings/sound/fsl,asrc.txt) inside. And
this is a specific feature that might be painstakingly controlled and merged
into the Simple Card driver.

So having this driver will allow all Freescale SoC users to benefit from the
simplification to support a new card and the capability of wide sample rates
support through ASRC.

The driver is initially designed for sound card using I2S or PCM DAI formats.
However, it's also possible to merge those non-I2S/PCM type sound cards, such
as S/PDIF audio and HDMI audio, into this card as long as the merge will not
break the original function and as long as there is something redundant that
can be abstracted along with I2S type sound cards.

As an initial version, it only supports three cards that I can test:
imx-audio-cs42888, a new card that links ESAI with CS42888 CODEC
imx-audio-sgtl5000, just like the old imx-sgtl5000.c driver
imx-audio-wm8962, just like the old imx-wm8962.c driver

The driver is also compatible with the old Device Tree bindings of WM8962 and
SGTL5000. So we may consider to remove those two drivers after this driver is
totally enabled. (It needs to be added into defconfig)
