ASoC: fsl-asoc-card: Defer probe when fail to find codec device
Defer probe when fail to find codec device, because the codec
device maybe probed later than machine driver.

ASoC: fsl-asoc-card: Support new property fsl, asrc-format
In order to align with new ESARC, we add new property fsl,asrc-format.
The fsl,asrc-format can replace the fsl,asrc-width, driver
can accept format from devicetree, don't need to convert it to
format through width.

ASoC: soc-core: find rtd via dai_link pointer at snd_soc_get_pcm_runtime()
Current snd_soc_get_pcm_runtime() is finding rtd by checking dai_link
name. But, it is strange and waste of CPU power, because its user want
to get from rtd from dai_link, not from dai_link name.
This patch find rtd via dai_link pointer instead of its name.

ASoC: fsl: fsl-asoc-card: consider CPU-Platform possibility
commit e57a4c2f15 ("ASoC: fsl: fsl-asoc-card: don't select unnecessary
Platform")

Current ALSA SoC avoid to add duplicate component to rtd,
and this driver was selecting CPU component as Platform component.
Thus, above patch removed Platform settings from this driver,
because it assumed these are same component.

But, some CPU driver is using generic DMAEngine, in such case, both
CPU component and Platform component will have same of_node/name.
In other words, there are some components which are different but
have same of_node/name.

In such case, Card driver definitely need to select Platform even
though it is same as CPU.
It is depends on CPU driver, but is difficult to know it from Card driver.
This patch reverts above patch.

ASoC: Use of_node_name_eq for node name comparisons
Convert string compares of DT node names to use of_node_name_eq helper
instead. This removes direct access to the node name pointer.

For the FSL ASoC card, the full node names appear to be "ssi", "esai",
and "sai", so there's not any reason to use strstr and of_node_name_eq
can be used instead.

ddba7fa4cf ASoC: constify snd_soc_ops structures
Check for snd_soc_ops structures that are only stored in the ops field of a
snd_soc_dai_link structure.  This field is declared const, so snd_soc_ops
structures that have this property can be declared as const also.

The semantic patch that makes this change is as follows:

089dfaf7f7 ASoC: fsl-asoc-card: Don't add DAPM routes for ASRC if it doesn't exist
There are a pair of warnings when ASRC is absent in the DTB:
  fsl-asoc-card sound: ASoC: no source widget found for ASRC-Playback
  fsl-asoc-card sound: ASoC: Failed to add route ASRC-Playback -> direct -> CPU-Playback
  fsl-asoc-card sound: ASoC: no sink widget found for ASRC-Capture
  fsl-asoc-card sound: ASoC: Failed to add route CPU-Capture -> direct -> ASRC-Capture

This is because the driver is still trying to add DAPM routes for ASRC
even if it doesn't exist on that platform.

The warnings are harmless but it might be annoying. So this patch drops
the DAPM routes of ASRC when it's absent in the DAI link.

50760cad9d ASoC: fsl-asoc-card: add AC'97 support
Add AC'97 support to fsl-asoc-card using generic
ASoC AC'97 CODEC.

The SSI controller will silently enable any TX
AC'97 slots that have their bits set in SLOTREQ
received from CODEC and then will redirect some
of playback samples there.

That's why it is important to make sure that
any of CODEC playback slots that can pull samples
are set to slots 3/4 (standard PCM playback slots).
Currently, this applies to S/PDIF slots as they
were seen to pull samples sometimes even with
S/PDIF output being disabled.

Add 'asrc_fail' branch for error jump after asrc_np initialized.

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)
