e720b82027 ALSA: ctxfi: prink replacement
as pr_* macros are more preffered over printk, so printk replaced with corresponding pr_err and pr_alert
this patch will generate a warning from checkpatch for an unnecessary space before new line and has not been fixed as this patch is only for printk replacement.

Right now we set 0 as the silence data for DSD_U8 and DSD_U16 formats,
but this is actually wrong.  0 is rather the most negative value.
Alternatively, we may take the repeating 0x69 pattern like ffmpeg

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.

Now that we have a unified probe and remove path make sure to call them for all

context for the component, initialize the component prefix, manage the debugfs

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.

f475371aa6 ALSA: hda - restore the gpio led after resume
On some HP laptops, the mute led is controlled by codec gpio.

When some machine resume from s3/s4, the codec gpio data will be
cleared to 0 by BIOS:
Before suspend:
  IO[3]: enable=1, dir=1, wake=0, sticky=0, data=1, unsol=0
After resume:
  IO[3]: enable=1, dir=1, wake=0, sticky=0, data=0, unsol=0

To skip the AFG node to enter D3 can't fix this problem.

A workaround is to restore the gpio data when the system resume
back from s3/s4. It is safe even on the machines without this
problem.

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.

e8a70c25b8 ASoC: samsung idma: Add proper annotation for casting iomem pointers
It is not always possible to interchange iomem pointers with normal pointers,
which why we have annotations for iomem pointers and warn when casting them to a
normal pointer or vice versa. In this case the casting is fine and unfortunately
necessary so add the proper annotations to tell code checkers that it is
intentional. This silences the following warnings from sparse:
	sound/soc/samsung/idma.c:354:20: warning: incorrect type in argument 1

6c7d1dfca9 ASoC: sh: Fix dma direction type
dmaengine_prep_slave_single() expects a enum dma_transfer_direction and not a
enum dma_data_direction. Since the integer representations of both DMA_TO_DEVICE
and DMA_MEM_TO_DEV aswell as DMA_FROM_DEVICE and DMA_DEV_TO_MEM have the same
value the code worked fine even though it was using the wrong type.

Fixes the following warnings from sparse:
	sound/soc/sh/fsi.c:1307:42: warning: mixing different enum types
	sound/soc/sh/fsi.c:1307:42:     int enum dma_data_direction  versus

c8e6e96073 ASoC: rcar: Use && instead of & for boolean expressions
Sparse spits out the following warning:
	sound/soc/sh/rcar/gen.c:250:21: warning: dubious: x & !y

It does this because sometimes mixing boolean and bit-wise logic has not the
intended result. In this case we are fine, but replacing the bit-wise '&' with
the boolean '&&' silences the sparse warning. The generated code for both cases
is the same.

855675f6e6 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).
