ASoC: soc-component: add snd_soc_component_remove()
Current ALSA SoC is directly using component->driver->xxx,
thus, it is deep nested, and makes code difficult to read,
and is not good for encapsulation.
This patch adds new snd_soc_component_remove() and use it.

ASoC: core: no need to check return value of debugfs_create functions
When calling debugfs functions, there is no need to ever check the
return value.  The function can work or not, but the code logic should
never do something different based on this.

Also, there is no need to store the individual debugfs file name, just
remove the whole directory all at once, saving a local variable.

Note, the soc-pcm "state" file has now moved to a subdirectory, as it is
only a good idea to save the dentries for debugfs directories, not
individual files, as the individual file debugfs functions are changing
to not return a dentry.

Masahiro Yamada dc3bf49ea3 treewide: remove SPDX "WITH Linux-syscall-note" from kernel-space headers again
The "WITH Linux-syscall-note" exception exists for headers exported to
user space. It is strange to add it to non-exported headers.

Commit 687a3e4d8e ("treewide: remove SPDX "WITH Linux-syscall-note"
from kernel-space headers") did cleanups some months ago, but it looks
like we need to do this periodically.

This patch was generated by the following script:

  git grep -l -e Linux-syscall-note \
    -- :*.h :^arch/*/include/uapi/asm/*.h :^include/uapi/ :^tools |
  while read file
  do
          sed -i -e 's/(\(GPL-[^[:space:]]*\) WITH Linux-syscall-note)/\1/g' \
          -e 's/ WITH Linux-syscall-note//g' $file
  done

I did not commit drivers/staging/android/uapi/ion.h . This header is
not currently exported, but somebody may plan to move it to include/uapi/
when the time comes. I am not sure. Anyway, it will be better to check
the license inconsistency in drivers/staging/android/uapi/.

Charles Keepax 4475f8c4ab ALSA: compress: Fix regression on compressed capture streams
A previous fix to the stop handling on compressed capture streams causes
some knock on issues. The previous fix updated snd_compr_drain_notify to
set the state back to PREPARED for capture streams. This causes some
issues however as the handling for snd_compr_poll differs between the
two states and some user-space applications were relying on the poll
failing after the stream had been stopped.

To correct this regression whilst still fixing the original problem the
patch was addressing, update the capture handling to skip the PREPARED
state rather than skipping the SETUP state as it has done until now.

Takashi Iwai 4914da2fb0 ALSA: hda - Don't resume forcibly i915 HDMI/DP codec
We apply the codec resume forcibly at system resume callback for
updating and syncing the jack detection state that may have changed
during sleeping.  This is, however, superfluous for the codec like
Intel HDMI/DP, where the jack detection is managed via the audio
component notification; i.e. the jack state change shall be reported
sooner or later from the graphics side at mode change.

This patch changes the codec resume callback to avoid the forcible
resume conditionally with a new flag, codec->relaxed_resume, for
reducing the resume time.  The flag is set in the codec probe.

Although this doesn't fix the entire bug mentioned in the bugzilla
entry below, it's still a good optimization and some improvements are
seen.

Takashi Iwai 774a075ab5 ALSA: hda: Simplify snd_hdac_refresh_widgets()
Along with the recent fix for the races of snd_hdac_refresh_widgets()
it turned out that the instantiation of widgets sysfs at
snd_hdac_sysfs_reinit() could cause a race.  The race itself was
already covered later by extending the mutex protection range, the
commit 98482377dc ("ALSA: hda: Fix widget_mutex incomplete
protection"), but this also indicated that the call of *_reinit() is
basically superfluous, as the widgets shall be created sooner or later
from snd_hdac_device_register().

This patch removes the redundant call of snd_hdac_sysfs_reinit() at
first.  By this removal, the sysfs argument itself in
snd_hdac_refresh_widgets() becomes superfluous, too, because the only
case sysfs=false is always with codec->widgets=NULL.  So, we drop this
redundant argument as well.

Add support platforms_num != 1 in dai_link. Initially, the main purpose of
this change was to make the platform optional in the dai_link, instead of
inserting the dummy platform driver.

This particular case had just been solved by Kuninori Morimoto with
commit 1d76898928 ("ASoC: soc-core: allow no Platform on dai_link").

However, this change may still be useful for those who need multiple
platform components on a single dai_link (it solves one of the FIXME
note in soc-core)

ASoC: soc-core: allow no Platform on dai_link
dai_link is used to selecting Component (= CPU/Codec/Platform) and
DAI (= CPU/Codec). And selected CPU/Codec/Platform components are
*listed* on Card.

Many drivers don't need special Platform component, but was
mandatory at legacy style ALSA SoC.
Thus, there is this kind of settings on many drivers.

	dai_link->platform_of_node = dai_link->cpu_of_node;

In this case, soc_bind_dai_link() will pick-up "CPU component" as
"Platform component", and try to add it to snd_soc_pcm_runtime.
But it will be ignored, because it is already added when CPU bindings.

Historically, this kind of "CPU component" is used/selected as
"Platform" on many ALSA SoC drivers.
OTOH, Dummy Platform will be selected automatically by ALSA SoC if
driver doesn't have Platform settings.

These indicates that there are 2 type of Platforms exist at current
ALSA SoC if driver doesn't need special Platform.

	1) use Dummy Platform as Platform component
	2) use CPU component  as Platform component

ALSA SoC will call Dummy Platform callback function if it is using
Dummy Platform, but it is completely pointless. Because it is the
sound card which doesn't need special Platform.

Thus, the behavior we request to ALSA SoC is selecting 2) automatically
instead of 1) if sound card doesn't need special Platform.
And, 2) means "do nothing" as above explain.

These were needed at legacy style dai_link, but is no longer needed
at modern style dai_link anymore.

This patch allows "no Platform" settings on dai_link, and will do
nothing for it if there was no platform settings. This is same as 2).

By this patch, all drivers which is selecting "CPU component" as
"Platform" can remove such settings.

Timer will be reset when DSP is powered down. So the time stamp of trace
log will be reset after resume. Send time stamp to FW can align the time

Linus Torvalds e57ccca1ba sound updates for 5.2-rc1
The most significant changes at this cycle are the Sound Open Firmware
 support from Intel for the common DSP framework along with its support
 for Intel platforms. It's a door opened to a real "free" firmware (in
 the sense of FOSS), and other parties show interests in it.
 
 In addition to SOF, we've got a bunch of updates and fixes as usual.
 Some highlights are below.
 
 ALSA core:
  - Cleanups and fixes in ALSA timer code to cover some races spotted
    by syzkaller
  - Cleanups and fixes in ALSA sequencer code to cover some races,
    again unsurprisingly, spotted by syzkaller
  - Optimize the common page allocation helper with alloc_pages_exact()
 
 ASoC:
  - Add SOF core support, as well as Intel SOF platform support
  - Generic card driver improvements: support for MCLK/sample rate
    ratio and pin switches
  - A big set of improvements to TLV320AIC32x4 drivers
  - New drivers for Freescale audio mixers, several Intel machines,
    several Mediatek machines, Meson G12A, Spreadtrum compressed audio
    and DMA devices
 
 HD-audio:
  - A few Realtek codec fixes for reducing pop noises
  - Quirks for Chromebooks
  - Workaround for faulty connection report on AMD/Nvidia HDMI
 
 Others:
  - A quirk for Focusrite Scarlett Solo USB-audio
  - Add support for MOTU 8pre FireWire
  - 24bit sample format support in aloop
  - GUS patch format support (finally, over a decade) in native
    emux synth code

Takashi Iwai d81645510c ASoC: Updates for v5.2
This is a pretty huge set of changes, it's been a pretty active release
 all round but the big thing with this release is the Sound Open Firmware
 changes from Intel, providing another DSP framework for use with the
 DSPs in their SoCs.  This one works with the firmware of the same name
 which is free software (unlike the previous DSP firmwares and framework)
 and there has been some interest in adoption by other systems already so
 hopefully we will see adoption by other vendors in the future.
 
 Other highlights incldue:
 
  - Support for MCLK/sample rate ratio setting in the generic cards.
  - Support for pin switches in the generic cards.
  - A big set of improvements to the TLV320AIC32x4 drivers from Annaliese
    McDermond.
  - New drivers for Freescale audio mixers, several Intel machines,
    several Mediatek machines, Meson G12A, Sound Open Firmware and
    Spreadtrum compressed audio and DMA devices.

Takashi Iwai f4fa968950 ALSA: core: Don't refer to snd_cards array directly
The snd_cards[] array holds the card pointers that have been currently
registered, and it's exported for the external modules that may need
to refer a card object.  But accessing to this array can be racy
against the driver probe or removal, as the card registration or free
may happen concurrently.

This patch gets rid of the direct access to snd_cards[] array and
provides a helper function to give the card object from the index
number with a refcount management.  Then the caller can access to the
given card object safely, and releases it via snd_card_unref().

While we're at it, add a proper comment to snd_card_unref() and make
it an inlined function for type-safety, too.

Takashi Iwai df55531b8b ALSA: timer: Revert active callback sync check at close
This is essentially a revert of the commit a7588c896b ("ALSA: timer:
Check ack_list emptiness instead of bit flag").  The intended change
by the commit turns out to be insufficient, as snd_timer_close*()
always calls snd_timer_stop() that deletes the ack_list beforehand.

In theory, we can change the behavior of snd_timer_stop() to sync the
pending ack_list, but this will become a deadlock for the callback
like sequencer that calls again snd_timer_stop() from itself.  So,
reverting the change is a more straightforward solution.

Ranjani Sridharan b4ed6b51f3
ASoC: core: conditionally increase module refcount on component open
Recently, for Intel platforms the "ignore_module_refcount" field
was introduced for the component driver. In order to avoid a
deadlock preventing the PCI modules from being removed
even when the card was idle, the refcounts were not incremented
for the device driver module during component probe.

However, this change introduced a nasty side effect:
the device driver module can be unloaded while a pcm stream is open.

This patch proposes to change the field to be renamed as
"module_get_upon_open". When this field is set, the module
refcount should be incremented on pcm open amd decremented
upon pcm close. This will enable modules to be removed
when no PCM playback/capture happens and prevent removal
when the component is actually in use.

Also, align with the skylake component driver with the new name.

Takashi Iwai 734b5a0bbd ALSA: Replace snd_malloc_pages() and snd_free_pages() with standard helpers, take#2
snd_malloc_pages() and snd_free_pages() are merely thin wrappers of
the standard page allocator / free functions.  Even the arguments are
compatible with some standard helpers, so there is little merit of
keeping these wrappers.

This patch replaces the all existing callers of snd_malloc_pages() and
snd_free_pages() with the direct calls of the standard helper
functions.  In this version, we use a recently introduced one,
alloc_pages_exact(), which suits better than the old
snd_malloc_pages() implementation for our purposes.  Then we can avoid
the waste of pages by alignment to power-of-two.

Since alloc_pages_exact() does split pages, we need no longer
__GFP_COMP flag; or better to say, we must not pass __GFP_COMP to
alloc_pages_exact().  So the former unconditional addition of
__GFP_COMP flag in snd_malloc_pages() is dropped, as well as in most
other places.

For checking the pending timer instance that is still left on the
timer object that is being closed, we set/clear a bit flag
SNDRV_TIMER_IFLG_CALLBACK around the call of callbacks.  This can be
simplified by replace with the list_empty() call for ti->ack_list.
This covers the existence more comprehensively and safely.

A gratis bonus is that we can get rid of SNDRV_TIMER_IFLG_CALLBACK bit
flag definition as well.

Historically, simple-card/simple-scu-card/audio-graph/audio-graph-scu

simple-scu-card which was for DPCM was merged into simple-card, and
audio-graph-scu which was for DPCM was merged into audio-graph.
simple-card is for non OF graph sound card, and
audio-graph is for     OF graph sound card.
And, small detail difference (= function parameter, naming, etc)
between simple-card/audio-graph has been unified.

master for the CPU and other codec devices, there is the need to
not only expose the clock gating of BCLK and WCLK but also the
ability to set those rates without going through the ASoC APIs.

To make this possible, the previous CCF implementation in the
driver has been extended to separate BCLK and WCLK out. WCLK is
the parent clock to BCLK, and is also the clock gate for both.
BCLK in HW is a factor/multiplier of WCLK so derives from whatever
SR is chosen for WCLK, hence the need to make it a child of WCLK
for the purposes of CCF. Enabling/disabling either BCLK or WCLK
will result in clocks being ungated/gated accordingly. To simplify
matters, these clocks can only be configured if the codec is set
as master, otherwise CCF control is disallowed.

Linus Torvalds 45763bf4bc Char/Misc driver patches for 5.1-rc1
Here is the big char/misc driver patch pull request for 5.1-rc1.
 
 The largest thing by far is the new habanalabs driver for their AI
 accelerator chip.  For now it is in the drivers/misc directory but will
 probably move to a new directory soon along with other drivers of this
 type.
 
 Other than that, just the usual set of individual driver updates and
 fixes.  There's an "odd" merge in here from the DRM tree that they asked
 me to do as the MEI driver is starting to interact with the i915 driver,
 and it needed some coordination.  All of those patches have been
 properly acked by the relevant subsystem maintainers.
 
 All of these have been in linux-next with no reported issues, most for
 quite some time.

Chris Wilson d31c85fc86 snd/hda, drm/i915: Track the display_power_status using a cookie
drm/i915 is tracking all wakeref owners with a cookie in order to
identify leaks. To that end, each rpm acquisition ops->get_power is
assigned a cookie which should be passed to ops->put_power to signify
its release (and removal from the list of wakeref owners). As snd/hda is
already using a bool to track current status of display_power extending
that to an unsigned long to hold the boolean cookie is a trivial
extension, and will quell all doubt that snd/hda is the cause of the
device runtime pm leaks.

v2: Keep using the power abstraction for local wakeref tracking.
v3: BUILD_BUG_ON impedance mismatch

ASoC: core: don't increase component module refcount unconditionally
The ASoC core has for the longest time increased the module reference
counts, even before the transition to the component model. This is
probably fine on most platforms, but it introduces a deadlock case on
Intel devices with the Skylake and SOF drivers which cannot be removed
due to their reference counts being modified by the core.

In these 2 cases, the PCI or ACPI driver .probe creates a platform
device to let the machine driver .probe register the audio
card. Conversely the PCI or ACPI driver .remove will unregister the
platform device which results in the card being removed by the machine
driver .remove.

With ascii art, this can be represented as

modprobe
snd_soc_skl/
soc-pci-dev/sof-acpci-dev  ----------> pci/acpi probe
       ^                                    |
       |                     ---------------|
       |                    |               |
       |                    V               V
    increase            register        register machine
    refcount            component       platform_device
       ^                                    |
       |                                    |
       |                                    V
    component <----   register card  <---- probe
    probe

The issue is that by playing with the component's module reference
counts during the card registration, it's no longer possible to remove
the module which controls the component. This can be shown, e.g. with
the following error:

root@plb-XPS-13-9350:~# lsmod | grep snd_soc_skl
snd_soc_skl           110592  1

root@plb-XPS-13-9350:~# rmmod snd_soc_skl
rmmod: ERROR: Module snd_soc_skl is in use

Increasing the reference count during the component probe is not
useful. If the PCI/ACPI module is removed, the card will be removed
anyway.

To avoid breaking existing platforms and allowing Intel platforms to
safely deal with module load/unload cases, this patch introduces a
flag which needs to be set during the component initialization. This
is a strictly opt-in capability that should only be used when the
handling of the component module does not require a reference count
increase to prevent removal during use.

Note that this solution is not directly applicable to the legacy
Atom/SST driver, which uses a different device hierarchy. There are
however additional refcount issues which prevent the ACPI driver from
being removed. This is a different issue which would need a different
patch.

Charles Keepax 4f2ab5e1d1 ALSA: compress: Fix stop handling on compressed capture streams
It is normal user behaviour to start, stop, then start a stream
again without closing it. Currently this works for compressed
playback streams but not capture ones.

The states on a compressed capture stream go directly from OPEN to
PREPARED, unlike a playback stream which moves to SETUP and waits
for a write of data before moving to PREPARED. Currently however,
when a stop is sent the state is set to SETUP for both types of
streams. This leaves a capture stream in the situation where a new
start can't be sent as that requires the state to be PREPARED and
a new set_params can't be sent as that requires the state to be
OPEN. The only option being to close the stream, and then reopen.

Correct this issues by allowing snd_compr_drain_notify to set the
state depending on the stream direction, as we already do in
set_params.

ASoC: dapm: Only power up active channels from a DAI
Currently all widgets attached to a DAI link will be powered
up when the DAI is active, however this may include routes
that are not actually in use if there are unused channels
available on the DAI.

The macros for creating AIF widgets already include an entry for
slot, it is proposed to change that to channel. The effective
difference here being respresenting the logical channel index
rather than the physical slot index. The CODECs currently
using the slot entry on the DAPM_AIF macros are using it in
a manner consistent with this, the CODECs not using it just
have the field set to zero.

A variable is added to snd_soc_dapm_widget to represent
this channel index and then for each AIF widget attached to
a DAI this is compared against the number of channels on
the stream. Enabling the links for those which will be in
use. This has the nice property that the CODECs which haven't
used the slot/channel entry in the macro will function exactly
as before due to all the AIF widgets having a channel of zero
and a stream by definition having at least one channel.

ASoC: add helper to change platform name for all dailinks
To reuse the same machine drivers with Atom/SST, Skylake and SOF, we
need to change the default platform_name (or platforms->name in the
"modern" representation).

So far, this override was done with an automatic override, which was
broken by a set of changes for DT platforms related to deferred probe
handling.

This automatic override is actually not really needed, the machine
driver can already receive the platform name as a platform_data
parameter. This is used e.g. for HDaudio support where we have
different PCI aliases used for different platforms. We can reuse the
same mechanism and modify the machine drivers to override the dailinks
prior to registrating the card.

This will require additional work for SOF, but with this helper it'll
be just two lines of additional code per machine driver which is
reused, not the end of the world.

This helper can be simplified when all drivers have transitioned to
the "modern" representation of dailinks.

Takashi Iwai f57f3df03a ALSA: pcm: More fine-grained PCM link locking
We have currently two global locks, a rwlock and a rwsem, that are
used for managing linking the PCM streams.  Due to these global locks,
once when a linked stream is used, the lock granularity suffers a
lot.

This patch attempts to eliminate the former global lock for atomic
ops.  The latter rwsem needs remaining because of the loosy way of the
loop calls in snd_pcm_action_nonatomic(), as well as for avoiding the
deadlock at linking.  However, these are used far rarely, actually
only by two actions (prepare and  reset), where both are no timing
critical ones.  So this can be still seen as a good improvement.

The basic strategy to eliminate the rwlock is to assure group->lock at
adding or removing a stream to / from the group.  Since we already
takes the group lock whenever taking the all substream locks under the
group, this shouldn't be a big problem.  The reference to group
pointer in snd_pcm_substream object is protected by the stream lock
itself.

However, there are still pitfalls: a race window at re-locking and the
lifecycle of group object.  The former is a small race window for
dereferencing the substream group object opened while snd_pcm_action()
performs re-locking to avoid ABBA deadlocks.  This includes the unlink
of group during that window, too.  And the latter is the kfree
performed after all streams are removed from the group while it's
still dereferenced.

For addressing these corner cases, two new tricks are introduced:
- After re-locking, the group assigned to the stream is checked again;
  if the group is changed, we retry the whole procedure.
- Introduce a refcount to snd_pcm_group object, so that it's freed
  only when it's empty and really no one refers to it.

(Some readers might wonder why not RCU for the latter.  RCU in this
case would cost more than refcounting, unfortunately.  We take the
group lock sooner or later, hence the performance improvement by RCU
would be negligible.  Meanwhile, because we need to deal with
schedulable context depending on the pcm->nonatomic flag, it'll become
dynamic RCU/SRCU switch, and the grace period may become too long.)

Along with these changes, there are a significant amount of code
refactoring.  The complex group re-lock & ref code is factored out to
snd_pcm_stream_group_ref() function, for example.

ASoC: soc.h: add explanation of legacy/modern style of dai_link
Current ALSA SoC is assuming 1 CPU 1 Platform (= DMA) style system.
Because of this background, it is directly using
xxx_name / xxx_of_node / xxx_dai_name on dai_link.
Let's call it as legacy style here.

More complex style system like multi CPU multi Platform (= DMA) will
coming. To supporting it, we can use snd_soc_dai_link_component on
dai_link. Let's call it as modern style here.
But current ALSA SoC can't support it so far. Thus, we need to have
multi CPU / multi Codec / multi Platform style in the future on ALSA SoC.

Currently we already have multi Codec support. Platform is starting to
use modern style on dai_link, but still style only. Multi Platform is
not yet implemented. And we still don't have multi CPU support on ALSA
SoC, and not have modern style either.

Currently, if driver is using legacy style Codec/Platform, it will be
converted to modern style on soc-core. This means, we are using glue code
for legacy vs modern style so far on ALSA SoC.
We can fully switch to modern style on all drivers if ALSA SoC supported
modern style for CPU, and then, legacy style code will be removed from
ALSA SoC.
Untile then, we need to keep both legacy/modern style and its glue code.
This patch adds such future plan and background on soc.h

ASoC: Fixes for v5.0

Quite a big batch of fixes here.  There's a couple of things going on,
the main one is that we found some issues with not deferring probe when
we should, causing us to skip some driver initialization.  The fixes for
this then in turn exposed some issues with how we were searching for
components which had previously gone unnoticed due to the original
issue.

There's also been the normal driver specific stuff and there's been what

generated quite a large set of smaller fixes for potential crashes and

Takashi Iwai 3d21ef0b49 ALSA: pcm: Suspend streams globally via device type PM ops
Until now we rely on each driver calling snd_pcm_suspend*() explicitly
at its own PM handling.  However, this can be done far more easily by
setting the PM ops to each actual snd_pcm device object.

This patch adds the device_type object for PCM stream and assigns to
each PCM stream object.  The type contains only the PM ops for system
suspend; we don't need to deal with the resume in general.

The suspend hook simply calls snd_pcm_suspend_all() for the given PCM
streams.  This implies that the PM order is correctly put, i.e. PCM is
suspended before the main (or codec) driver, which should be true in
general.  If a special ordering is needed, you'd need to adjust the
device PM order manually later.

This patch introduces a new flag, snd_pcm.no_device_suspend, too.
With this flag set, the PCM device object won't invoke
snd_pcm_suspend_all() by itself.  This is needed for ASoC who wants to
manage the PM call orders in its serialized way, and the flag is set
in soc_new_pcm() as default.

For the non-ASoC world, we can get rid of the manual snd_pcm_suspend
calls.  This will be done in the later patches.

ASoC: soc-core: fix init platform memory handling
snd_soc_init_platform initializes pointers to snd_soc_dai_link which is
statically allocated and it does this by devm_kzalloc. In the event of
an EPROBE_DEFER the memory will be freed and the pointers are left
dangling. snd_soc_init_platform sees the dangling pointers and assumes
they are pointing to initialized memory and does not reallocate them on
the second probe attempt which results in a use after free bug since
devm has freed the memory from the first probe attempt.

Since the intention for snd_soc_dai_link->platform is that it can be set
statically by the machine driver we need to respect the pointer in the
event we did not set it but still catch dangling pointers. The solution
is to add a flag to track whether the pointer was dynamically allocated
or not.

Takashi Iwai 029d92c289 ALSA: hda: Refactor display power management
The current HD-audio code manages the DRM audio power via too complex
redirections, and this seems even still unbalanced in a corner case as
Intel DRM CI has been intermittently reporting.  This patch is a big
surgery for addressing the complexity and the possible unbalance.

Basically the patch changes the display PM in the following ways:

- Both HD-audio controller and codec drivers call a single helper,
  snd_hdac_display_power().  (Formerly, the display power control from
  a codec was done indirectly via link_power bus ops.)

- snd_hdac_display_power() receives the codec address index.  For
  turning on/off from the controller, pass HDA_CODEC_IDX_CONTROLLER.

- snd_hdac_display_power() doesn't manage refcounts any longer, but
  keeps the power status in bitmap.  If any of controller or codecs is
  turned on, the function updates the DRM power state via get_power()
  or put_power().

Also this refactor allows us more cleanup:

- The link_power bus ops is dropped, so there is no longer indirect
  management, as mentioned in the above.

- hdac_device link_power_control flag is moved to hda_codec
  display_power_control flag, as it's only for HDA legacy.

ASoC: fix oops w/ for_each_rtd_codec_dai_rollback() macro
A kernel oops happens on an error case (usual missing BE mixer
configuration required by Intel SST driver). Git bisect points to this
macro and an operator precedence issue.

	for (; ((i--) >= 0) && ((dai) = rtd->codec_dais[i]);)

The initial code replaced by this macro was
	while (--i >= 0) {
		codec_dai = rtd->codec_dais[i];

Fix the C operator precedence difference by reverting to pre-decrement

Takashi Iwai 5e3cdecf78 ASoC: Updates for v5.0/v4.20
As ever there's a lot of small and driver specific changes going on
 here, but we do also have some relatively large changes in the core
 thanks to the hard work of Charles and Morimoto-san:
 
  - More component transitions from Morimoto-san, I think we're about
    finished with this.  Thanks for all the hard work!
  - Morimoto-san also added a bunch of for_each_foo macros
  - A bunch of cleanups and fixes for DAPM from Charles.
  - MCLK support for several different devices, including CS42L51, STM32
    SAI, and MAX98373.
  - Support for Allwinner A64 CODEC analog, Intel boards with DA7219 and
    MAX98927, Meson AXG PDM inputs, Nuvoton NAU8822, Renesas R8A7744 and
    TI PCM3060.

sound: don't call skl_init_chip() to reset intel skl soc
Internally, skl_init_chip() calls snd_hdac_bus_init_chip() which
1) sets bus->chip_init to prevent multiple entrances before device
is stopped; 2) enables interrupt.

We shouldn't use it for the purpose of resetting device only because
1) when we really want to initialize device, we won't be able to do
so; 2) we are ready to handle interrupt yet, and kernel crashes when
interrupt comes in.

Rename azx_reset() to snd_hdac_bus_reset_link(), and use it to reset
device properly.

ASoC: core: add support to card rebind
Current behaviour of ASoC core w.r.t to component removal is that it
unregisters dependent sound card totally. There is no support to
rebind the card if the component comes back.
Typical use case is DSP restart or kernel modules itself.

With this patch, core now maintains list of cards that are unbind due to
any of its depended components are removed and card not unregistered yet.
This list is cleared when the card is rebind successfully or when the
card is unregistered from machine driver.

This list of unbind cards are tried to bind once again after every new
component is successfully added, giving a fair chance for card bind
to be successful.
