Clemens Ladisch 1001fb810b ALSA: seq: increase the maximum number of queues
Queues are used both for scheduling playback events and for assigning
timestamps to recorded events, so it is easy to need quite a lot of
them, especially on a multi-user system.  Additionally, the actual
queue objects are allocated dynamically, so it does not really make
sense to have a low limit.  Increase it to something still sane.

Lars-Peter Clausen 96da4e5b2e ASoC: Remove codec field from snd_soc_dapm_widget
There are no more users of this field left so it can finally be removed.
New users should use snd_soc_dapm_to_codec(w->dapm);

The reason why it is removed is because it doesn't fit to well anymore in
the componentized ASoC hierarchy, where DAPM works on the snd_soc_component
level. And the alternative of snd_soc_dapm_to_codec(w->dapm) typically
generates the same amount of code, so there is really no reason to keep it.

For automatic conversion the following coccinelle semantic patch can be used:
// <smpl>
@@
struct snd_soc_dapm_widget *w;
@@
-w->codec
+snd_soc_dapm_to_codec(w->dapm)
// </smpl>

Lars-Peter Clausen ce64c8b9cf ASoC: Add helper function for changing the DAI link format
For some setups it is necessary to change the DAI link format at runtime.
This patch factors out the code that does the initial static DAI link format
configuration into a separate helper function which can be used board
drivers as well.

This allows board drivers that have to change the DAI link format at runtime
to reuse it instead of having to manually change the format on all DAIs.

Lars-Peter Clausen fa60c06569 ALSA: wss: Remove (almost) always NULL parameters
Most callers of snd_wss_pcm(), snd_wss_timer() and snd_cs4236_pcm() pass
NULL as the last parameter, some callers pass a pointer but never use it
after the function has been called and only a few callers pass a pointer and
actually use it. The later is only the case for snd_wss_pcm() for
snd_cs4236_pcm() and it is possible to get the same PCM object by accessing
the pcm field of the snd_wss struct that was passed as the first parameter.

This function removes the last parameters from the functions mentioned above
and updates the callers which used it to use chip->pcm instead. This allows
us to slightly simplify the functions since they don't have to check and set
the last parameter anymore which makes the code slightly shorter and
cleaner.

Lars-Peter Clausen 599ee3291a ALSA: pcm: Use __ffs() instead of ffs() in snd_mask_min()
The difference between __ffs and ffs is that ffs will return a one based
index whereas __ffs will return a zero based index. Furthermore ffs will
check if the passed value is zero and return zero in that case, whereas
__ffs behavior is undefined if the passed parameter is 0.

Since we already check if the mask is 0 before calling ffs and also subtract
1 from the result __ffs is the better choice.

Lars-Peter Clausen 86d7500326 ASoC: dapm: Simplify fully route card handling
For legacy reasons the ASoC framework assumes that a CODEC INPUT or OUTPUT
widget that is not explicitly connected to a external source or sink is
potentially connected to a source or a sink and hence the framework treats
the widget itself as source (for INPUT) or sink (for OUTPUT). For this
reason a INPUT or OUTPUT widget that is really not connected needs to be
explicitly marked as so.

Setting the card's fully_routed flag will cause the ASoC core, once that all
widgets and routes have been registered, to go through the list of all
widgets and mark all INPUT and OUTPUT that are not externally connected as
non-connected. This essentially negates the default behaviour of treating
INPUT or OUTPUT widgets without external routes as sources or sinks.

This patch takes a different approach while getting the same result. Instead
of first marking INPUT and OUTPUT widgets as sinks/sources and then later
marking them as non-connected, just never mark them as a sink or a source if
the fully_routed flag is set on a card.

This requires a lot less code and also results in a slightly faster card
initialization since there is no need to iterate over all widgets and check
whether the INPUT and OUTPUT widgets are connected or not.

Linus Torvalds bae41e45b7 sound updates for 3.19-rc1
This became a fairly large pull request.  In addition to the usual
 driver updates / fixes, there have been a high amount of cleanups in
 ASoC area, as well as control API helpers and kernel documentations
 fixes touching through the whole tree.
 
 In the driver side, the biggest changes are the support for new Intel
 SoC found on new x86 machines, and the updates of FireWire dice and
 oxfw drivers.
 
 Some remarkable items are below:
 
 * ALSA core
  - PCM mmap code cleanup, removal of arch-dependent codes
  - PCM xrun injection support
  - PCM hwptr tracepoint support
  - Refactoring of snd_pcm_action(), simplification of PCM locking
  - Robustified sequecner auto-load functionality
  - New control API helpers and lots of cleanups along with them
  - Lots of kerneldoc fixes and cleanups
 
 * USB-audio
  - The mixer resume code was largely rewritten, and the devices with
    quirks are resumed properly.
  - New hardware support: Focusrite Scarlett, Digidesign Mbox1,
    Denon/Marantz DACs, Zoom R16/24
 
 * FireWire
  - DICE driver updates with better duplex and sync support, including
    MIDI support
  - New OXFW driver for Oxford Semiconductor FW970/971 chipset,
    including the previous LaCie Speakers device.  Fullduplex and MIDI
    support included as well as DICE driver.
 
 * HD-audio
  - Refactoring the driver-caps quirk handling in snd-hda-intel
  - More consistent control names representing the topology better
  - Fixups: HP mute LED with ALC268 codec, Ideapad S210 built-in mic
    fix, ASUS Z99He laptop EAPD
 
 * ASoC
  - Conversion of AC'97 drivers to use regmap, bringing us closer to
    the removal of the ASoC level I/O code
  - Clean up a lot of old drivers that were open coding things that
    have subsequently been implemented in the core
  - Some DAPM performance improvements
  - Removal of the now seldom used CODEC mutex
  - Lots of updates for the newer Intel SoC support, including support
    for the DSP and some Cherrytrail and Braswell machine drivers
  - Support for Samsung boards using rt5631 as the CODEC
  - Removal of the obsolete AFEB9260 machine driver
  - Driver support for the TI TS3A227E headset driver used in some
    Chrombeooks
 
 * Others
  - ASIHPI driver update and cleanups
  - Lots of dev_*() printk conversions
  - Lots of trivial cleanups for the codes spotted by Coccinelle

As Russell King's explained it, there should not be pointers to
struct device_node:

"struct device_node is a ref-counted structure.  That means if you
 store a reference to it, you should "get" it, and you should "put"
 it once you've done.  The act of "put"ing the pointed-to structure
 involves writing to that structure, so it is totally unappropriate
 to store a device_node structure as a const pointer.  It forces you
 to have to cast it back to a non-const pointer at various points
 in time to use various OF function calls."

[This isn't quite the application here, we're not geting or putting the
pointer though we did add some other users who call non-const OF
functions -- broonie]

commit f0fba2ad1b ("ASoC: multi-component - ASoC Multi-Component Support")

SND_SOC_BIAS_ON in probe, just for the ASoC core to put it back into

Lars-Peter Clausen bc26321404 ASoC: Rename snd_soc_dai_driver struct ac97_control field to bus_control
Setting the ac97_control field on a CPU DAI tells the ASoC core that this
DAI in addition to audio data also transports control data to the CODEC.
This causes the core to suspend the DAI after the CODEC and resume it before
the CODEC so communication to the CODEC is still possible. This is not
necessarily something that is specific to AC'97 and can be used by other
buses with the same requirement. This patch renames the flag from
ac97_control to bus_control to make this explicit.

While we are at it also change the type from int to bool.

The following semantich patch was used for automatic conversion of the
drivers:
// <smpl>

allocating a snd_ac97_bus in snd_soc_new_ac97_codec() just use a static one

Also drop the device number parameter from snd_soc_new_ac97_codec(). We
currently only support one device per bus and all drivers pass 0 for the
device number. And if we should ever support multiple devices per bus it
wouldn't be up to individual AC'97 device drivers to pick their number, but
rather either the AC'97 adapter driver or the core code will assign them.

Takashi Iwai ea9d0d771f ASoC: dpcm: Fix race between FE/BE updates and trigger
DPCM can update the FE/BE connection states totally asynchronously
from the FE's PCM state.  Most of FE/BE state changes are protected by
mutex, so that they won't race, but there are still some actions that
are uncovered.  For example, suppose to switch a BE while a FE's
stream is running.  This would call soc_dpcm_runtime_update(), which
sets FE's runtime_update flag, then sets up and starts BEs, and clears
FE's runtime_update flag again.

When a device emits XRUN during this operation, the PCM core triggers
snd_pcm_stop(XRUN).  Since the trigger action is an atomic ops, this
isn't blocked by the mutex, thus it kicks off DPCM's trigger action.
It eventually updates and clears FE's runtime_update flag while
soc_dpcm_runtime_update() is running concurrently, and it results in
confusion.

Usually, for avoiding such a race, we take a lock.  There is a PCM
stream lock for that purpose.  However, as already mentioned, the
trigger action is atomic, and we can't take the lock for the whole
soc_dpcm_runtime_update() or other operations that include the lengthy
jobs like hw_params or prepare.

This patch provides an alternative solution.  This adds a way to defer
the conflicting trigger callback to be executed at the end of FE/BE
state changes.  For doing it, two things are introduced:

- Each runtime_update state change of FEs is protected via PCM stream
  lock.
- The FE's trigger callback checks the runtime_update flag.  If it's
  not set, the trigger action is executed there.  If set, mark the
  pending trigger action and returns immediately.
- At the exit of runtime_update state change, it checks whether the
  pending trigger is present.  If yes, it executes the trigger action
  at this point.

Lars-Peter Clausen 92a99ea439 ASoC: dapm: Use more aggressive caching
Currently we cache the number of input and output paths going to/from a
widget only within a power update sequence. But not in between power update
sequences.

But we know how changes to the DAPM graph affect the number of input (form a
source) and output (to a sink) paths of a widget and only need to
recalculate them if a operation has been performed that might have changed
them.
	* Adding/removing or connecting/disconnecting a path means that the for
	  the source of the path the number of output paths can change and for
	  the sink the number of input paths can change.
	* Connecting/disconnecting a widget has the same effect has connecting/
	  disconnecting all paths of the widget. So for the widget itself the
	  number of inputs and outputs can change, for all sinks of the widget
	  the number of inputs can change and for all sources of the widget the
	  number of outputs can change.
	* Activating/Deactivating a stream can either change the number of
	  outputs on the sources of the widget associated with the stream or the
	  number of inputs on the sinks.

Instead of always invalidating all cached numbers of input and output paths
for each power up or down sequence this patch restructures the code to only
invalidate the cached numbers when a operation that might change them has
been performed. This can greatly reduce the number of DAPM power checks for
some very common operations.

Since per DAPM operation typically only either change the number of inputs
or outputs the number of path checks is reduced by at least 50%. The number
of neighbor checks is also reduced about the same percentage, but since the
number of neighbors encountered when walking from sink to source is not the
same as when walking from source to sink the actual numbers will slightly
vary from card to card (e.g. for a mixer we see 1 neighbor when walking from
source to sink, but the number of inputs neighbors when walking from source
to sink).

Bigger improvements can be observed for widgets with multiple connected
inputs and output (e.g. mixers probably being the most widespread form of
this). Previously we had to re-calculate the number of inputs and outputs
on all input and output paths. With this change we only have to re-calculate
the number of outputs on the input path that got changed and the number of
inputs on the output paths.

E.g. imagine the following example:

	A --> B ----.
	            v
	M --> N --> Z <-- S <-- R
	            |
	            v
	            X

Widget Z has multiple input paths, if any change was made that cause Z to be
marked as dirty the power state of Z has to be re-computed. This requires to
know the number of inputs and outputs of Z, which requires to know the
number of inputs and outputs of all widgets on all paths from or to Z.
Previously this meant re-computing all inputs and outputs of all the path
going into or out of Z. With this patch in place only paths that actually
have changed need to be re-computed.

If the system is idle (or the part of the system affected by the changed
path) the number of path checks drops to either 0 or 1, regardless of how
large or complex the DAPM context is. 0 if there is no connected sink and no
connected source. 1 if there is either a connected source or sink, but not
both. The number of neighbor checks again will scale accordingly and will be
a constant number that is the number of inputs or outputs of the widget for
which we did the path check.

When loading a state file or switching between different profiles typically
multiple mixer and mux settings are changed, so we see the benefit of this
patch multiplied for these kinds of operations.

Testing with the ADAU1761 shows the following changes in DAPM stats for
changing a single Mixer switch for a Mixer with 5 inputs while the DAPM
context is idle.

Before:  2      12    30
After:   2       1     2

Lars-Peter Clausen 8be4da29cf ASoC: dapm: Mark endpoints instead of IO widgets dirty during suspend/resume
The state of endpoint widgets is affected by that card's power state.
Endpoint widgets that do no have the ignore_suspend flag set will be
considered inactive during suspend. So they have to be re-checked and marked
dirty after the card's power state changes. Currently the input and output
widgets are marked dirty instead, this works most of the time since
typically a path from one endpoint to another will go via a input or output
widget. But marking the endpoints dirty is technically more correct and will
also work for odd corner cases.

Lars-Peter Clausen c1862c8bae ASoC: dapm: Add a flag to mark paths connected to supply widgets
Supply widgets do not count towards the input and output widgets of their
neighbors and for supply widgets themselves we do not care for the number
of input or output paths. This means that a path that connects to a supply
widget effectively behaves the same as a path that as the weak property set.
This patch adds a new path flag that gets set to true when the path is
connected to at least one supply widget. If a path with the flag set is
encountered in is_connected_{input,output}_ep() is is skipped in the same
way that weak paths are skipped. This slightly brings down the number of
path checks.

Since both the weak and the supply flag are implemented as bitfields which
are stored in the same word there is no runtime overhead due to checking
both rather than just one and also the size of the path struct is not
increased by this patch. Another advantage is that we do not have to handle
supply widgets in is_connected_{input,output}_ep() anymore since it will
never be called for supply widgets. The only exception is from
dapm_widget_power_read_file() where a check is added to special case supply
widgets.

Testing with the ADAU1761, which has a handful of supply widgets, shows the
following changes in the DAPM stats for a playback stream start.

Lars-Peter Clausen 6dd98b0a3e ASoC: dapm: Introduce toplevel widget categories
DAPM widgets can be classified into four categories:
	* supply: Supply widgets do not affect the power state of their
		non-supply widget neighbors and unlike other widgets a
		supply widget is not powered up when it is on an active
		path, but when at least on of its neighbors is powered up.
	* source: A source is a widget that receives data from outside the
		DAPM graph or generates data. This can for example be a
		microphone, the playback DMA or a signal generator. A source
		widget will be considered powered up if there is an active
		path to a sink widget.
	* sink: A sink is a widget that transmits data to somewhere outside
		of the DAPM graph. This can e.g. be a speaker or the capture
		DMA. A sink widget will be considered powered up if there is
		an active path from a source widget.
	* normal: Normal widgets are widgets not covered by the categories
		above. A normal widget will be considered powered up if it
		is on an active path between a source widget and a sink
		widget.

The way the number of input and output paths for a widget is calculated
depends on its category. There are a bunch of factors which decide which
category a widget is. Currently there is no formal classification of these
categories and we calculate the category of the widget based on these
factors whenever we want to know it. This is at least once for every widget
during each power update sequence. The factors which determine the category
of the widgets are mostly static though and if at all change rather seldom.
This patch introduces three new per widget flags, one for each of non-normal
widgets categories. Instead of re-computing the category each time we want
to know them the flags will be checked. For the majority of widgets the
category is solely determined by the widget id, which means it never changes
and only has to be set once when the widget is created. The only widgets
with dynamic categories are:

	snd_soc_dapm_dai_out: Is considered a sink iff the capture stream is
		active, otherwise normal.
	snd_soc_dapm_dai_in: Is considered a source iff the playback stream
		is active, otherwise normal.
	snd_soc_dapm_input: Is considered a sink iff it has no outgoing
		paths, otherwise normal.
	snd_soc_dapm_output: Is considered a source iff it has no incoming
		paths, otherwise normal.
	snd_soc_dapm_line: Is considered a sink iff it has no outgoing paths
		and is considered a source iff it has no incoming paths,
		otherwise normal.

For snd_soc_dapm_dai_out/snd_soc_dapm_dai_in widgets the category will be
updated when a stream is started or stopped. For the other dynamic widgets
the category will be updated when a path connecting to it is added or
removed.

Introducing those new widget categories allows to make
is_connected_{output,input}_ep, which are among the hottest paths of the
DAPM algorithm, more generic and significantly shorter.

The before and after sizes for is_connected_{output,input}_ep are:

On ARM (defconfig + CONFIG_SND_SOC):
	function                                     old     new   delta
	is_connected_output_ep                       480     340    -140
	is_connected_input_ep                        456     352    -104

On amd64 (defconfig + CONFIG_SND_SOC):
	function                                     old     new   delta
	is_connected_output_ep                       579     427    -152
	is_connected_input_ep                        563     427    -136

Which is about a 25%-30% decrease, other architectures are expected to have
similar numbers. At the same time the size of the snd_soc_dapm_widget struct
does not change since the new flags are stored in the same word as the
existing flags.

Note: that since the per widget 'ext' flag was only used to decide whether a
snd_soc_dapm_input or snd_soc_dapm_output widget was a source or a sink it
is now unused and can be removed.

Lars-Peter Clausen 130897ac5a ASoC: dapm: Remove path 'walked' flag
The 'walked' flag was used to avoid walking paths that have already been
walked. But since we started caching the number of inputs and outputs of a
path we never actually get into a situation where we try to walk a path that
has the 'walked' flag set.

There are two cases in which we can end up walking a path multiple times
within a single run of is_connected_output_ep() or is_connected_input_ep().

1) If a path splits up and rejoins later:

	     .--> C ---v
	A -> B         E --> F
	     '--> D ---^

When walking from A to F we'll end up at E twice, once via C and once via D.
But since we do a depth first search we'll fully discover the path and
initialize the number of outputs/inputs of the widget the first time we get
there. The second time we get there we'll use the cached value and not
bother to check any of the paths again. So we'll never see a path where
'walked' is set in this case.

2) If there is a circle:

	A --> B <-- C <-.--> F
	      '--> D ---'

When walking from A to F we'll end up twice at B. But since there is a
circle the 'walking' flag will still be set on B once we get there the
second time. This means we won't look at any of it's outgoing paths. So in
this case we won't ever see a path where 'walked' is set either.

So it is safe to remove the flag. This on one hand means we remove some
always true checks from one of the hottest paths of the DAPM algorithm and
on the other hand means we do not have to do the tedious clearing of the
flag after checking the number inputs or outputs of a widget.

Takashi Iwai 68ab61084d ALSA: seq: bind seq driver automatically
Currently the sequencer module binding is performed independently from
the card module itself.  The reason behind it is to keep the sequencer
stuff optional and allow the system running without it (e.g. for using
PCM or rawmidi only).  This works in most cases, but a remaining
problem is that the binding isn't done automatically when a new driver
module is probed.  Typically this becomes visible when a hotplug
driver like usb audio is used.

This patch tries to address this and other potential issues.  First,
the seq-binder (seq_device.c) tries to load a missing driver module at
creating a new device object.  This is done asynchronously in a workq
for avoiding the deadlock (modprobe call in module init path).

This action, however, should be enabled only when the sequencer stuff
was already initialized, i.e. snd-seq module was already loaded.  For
that, a new function, snd_seq_autoload_init() is introduced here; this
clears the blocking of autoloading, and also tries to load all pending
driver modules.

Lars-Peter Clausen 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.

Takashi Iwai 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.

Takashi Iwai 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.

Lars-Peter Clausen 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.

Unfortunately there are still a couple of CODEC specific debugfs files that are

added to the component struct that will be initialized when a CODEC is

no drivers left using legacy IO this can be removed again.

Nicolin Chen 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.

some cases, the same CPU DAI can be connected to several codecs.

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.

This patch adds Realtek ALC286 codec driver.

ALC286 is a dual mode codec, which can run as HD-A or I2S mode.
It is controlled by HD-A verb commands via I2C protocol.
The following is the I/O difference between ALC286 and general I2S codecs.
1. A HD-A verb command contains three parts, NID, VID, and PID.
   And an I2S command contains only two parts: address and data.
2. Not only the register address is written, but the read command also
   includes the entire write command.
3. rt286 uses different registers for read and write the same bits.

We map verb command to regmap structure. However, we read most registers from
cache to prevent the asymmetry read/write issue in rt286.

(Current driver is assuming 1st SSITDR/SSIRDR for it)

2nd SSIn_BUSIF can be used as FIFO.
This is very helpful/useful for SSI+DMA.

But DMA address / DMA ID are not same between 1st/2nd cases.
This patch care about these settings.

The platform field in the snd_soc_dapm_widget and snd_soc_dapm_context structs
is now unused can be removed. New code that wants to get the platform for a
widget or dapm context should use snd_soc_dapm_to_platform(w->dapm) or
snd_soc_dapm_to_platform(dapm).

Lars-Peter Clausen 9420d97b3f ASoC: dapm: Remove DAI DAPM context
The DAI DAPM context was added in commit be09ad90 ("ASoC: core: Add platform DAI
widget mapping") and the only user was removed again in commit ae10e7e8f ("ASoC:
core: Only add platform DAI widgets once."). Now that we have a per component
DAPM context it is unlikely that we'll need the DAI DAPM context again.

Lars-Peter Clausen 14e8bdebfb ASoC: Add component level stream_event() and seq_notifier() support
This patch adds stream_event() and seq_notifier() callbacks similar to those
found in the snd_soc_codec_driver and snd_soc_platform driver struct to the
snd_soc_component_driver struct. This is meant to unify the handling of these
callbacks across different types of components and will eventually allow their
removal from the CODEC and platfrom driver structs.

The new callbacks are slightly different from the old ones in that they take a
snd_soc_component as a parameter rather than a snd_soc_dapm_context. This was
done since otherwise casting from the DAPM context to the component would
typically be the first thing to do in the callback. And the interface becomes
slightly cleaner by passing a snd_soc_component to all callbacks in the
snd_soc_component_driver struct.

The patch also already removes the stream_event() callback from the
snd_soc_codec_driver and snd_soc_platform_driver structs as it is currently
unused.

Lars-Peter Clausen ce0fc93ae5 ASoC: Add DAPM support at the component level
This patch adds full DAPM support at the component level. Previously there was
only full DAPM support for CODECs and partial DAPM support (e.g. no Mixers nor
MUXs) for platforms. Having DAPM support at the component level will allow all
types of components to use DAPM and also help in consolidating the DAPM support
between CODECs and platforms.

Since the DAPM context is directly embedded into the snd_soc_codec and
snd_soc_platform struct and the 'dapm' field is directly referenced in a lot of
drivers moving the field just right now is not possible without causing code
churn. The approach this patch takes is to add two new fields to the component
struct. One field which is the pointer to the actual DAPM context used by the
component and one DAPM context that will be used as the default if no other
context was specified. For CODECs and platforms the pointer is initialized to
point to the CODEC or platform DAPM context. All generic code when referencing
a component's DAPM struct will go via the pointer. This will make it possible to
eventually seamlessly move the DAPM context from snd_soc_codec and
snd_soc_platform struct over once all direct references have been eliminated.

Lars-Peter Clausen 68f831c272 ASoC: Add a set_bias_level() callback to the DAPM context struct
Currently the DAPM code directly looks at the CODEC driver struct to get a
handle to the set_bias_level() callback. This patch adds a new set_bias_level()
callback to the DAPM context struct. The DAPM code will use this new callback
instead of the CODEC callback. For CODECs the new callback is set up to call the
CODEC specific set_bias_level callback(). Not looking directly at the CODEC
driver struct will allow non CODEC DAPM contexts to implement a set_bias_level()
callback.

This is also similar to how the seq_notifier() and stream_event() callbacks are
currently handled.

Lars-Peter Clausen 7df3788410 ASoC: Auto disconnect pins from all DAPM contexts
Currently only pins in CODEC DAPM contexts are automatically marked as
non-connected if the card has the fully_routed flag set. This makes sense since
widgets which qualify for auto-disconnection are only found in CODEC DAPM
contexts. But with componentisation this is going to change, so consider all
widgets for auto-disconnection.

Also it is probably faster to walk the widgets list only once rather than once
for each CODEC.

Move the name_prefix from the CODEC struct to the component struct. This will
eventually allow to specify prefixes for all types of components. It is also
necessary to make the DAPM code component type independent (i.e. a DAPM context
does not need to know whether it belongs to a CODEC or a platform or something
else).

Lars-Peter Clausen 07f4d9d74a ALSA: control: Protect user controls against concurrent access
The user-control put and get handlers as well as the tlv do not protect against
concurrent access from multiple threads. Since the state of the control is not
updated atomically it is possible that either two write operations or a write
and a read operation race against each other. Both can lead to arbitrary memory
disclosure. This patch introduces a new lock that protects user-controls from
concurrent access. Since applications typically access controls sequentially
than in parallel a single lock per card should be fine.
