79e8b218b3 ALSA: emu10k1: Allocate resources with device-managed APIs
This patch converts the resource management in PCI emu10k1 driver with
devres as a clean up.  Each manual resource management is converted
with the corresponding devres helper, the page allocations are done
with the devres helper, and the card object release is managed now via
card->private_free instead of a lowlevel snd_device.

This should give no user-visible functional changes.

c2b94954ad ALSA: core: Add device-managed request_dma()
This patch adds a devres-supported helper for requesting an ISA DMA
channel that will be automatically freed at the device unbinding.
It'll be used by quite a few ISA sound drivers.

e8ad415b7a ALSA: core: Add managed card creation
As a second step for preliminary to widen the devres usages among
sound drivers, this patch adds a new ALSA core API function,
snd_devm_card_new(), to create a snd_card object via devres.
When a card object is created by this new function, snd_card_free() is
called automatically and the card object resource gets released at the
device unbinding time.

However, the story isn't that simple.  A caveat is that we have to
call snd_card_free() at the very first of the whole resource release
procedure, in order to assure that the all exposed devices on
user-space are deleted and sync with processes accessing those devices
before releasing resources.

For achieving it, snd_card_register() adds a new devres action to
trigger snd_card_free() automatically when the given card object is a
"managed" one.  Since usually snd_card_register() is the last step of
the initialization, this should work in most cases.

With all these tricks, some drivers can get rid of the whole driver
remove callback code.

About a bit of implementation details: the patch adds two new flags to
snd_card object: managed and releasing.  The former indicates that the
object was created via snd_devm_card_new(), and the latter is used for
avoiding the double-free of snd_card_free() calls.  Both flags are
fairly internal and likely uninteresting to normal users.

427ae2689d ALSA: core: Add device-managed page allocator helper
This is a preparation for allowing devres usages more widely in
various sound drivers.  As a first step, this patch adds a new
allocator function, snd_devm_alloc_pages(), to manage the allocated
pages via devres, so that the pages will be automagically released as
device unbinding.

Unlike the old snd_dma_alloc_pages(), the new function returns
directly the snd_dma_buffer pointer.  The caller needs NULL-check for
the allocation error appropriately.

Also, since a real device pointer is mandatory for devres,
SNDRV_DMA_TYPE_CONTINUOUS or SNDRV_DMA_TYPE_VMALLOC type can't be used
for this function.

ASoC: soc-core: add snd_soc_daifmt_parse_format/clock_provider()
snd_soc_of_parse_daifmt() parses daifmt, but bitclock/frame provider
parsing part is one of headacke, because we are assuming below both cases.

A)	node {
		bitclock-master;
		frame-master;
		...
	};

B)	link {
		bitclock-master = <&xxx>;
		frame-master = <&xxx>;
		...
	};

The original was style A), and style B) was added later
by commit b3ca11ff59 ("ASoC: simple-card: Move dai-link level
properties away from dai subnodes").

snd_soc_of_parse_daifmt() parses it as style A),
and user need to update it to style B) if needed.

To handle it more flexibile, this patch adds new functions
which separates snd_soc_of_parse_daifmt() helper function.

 snd_soc_daifmt_parse_format()			 :for DAI format
 snd_soc_daifmt_parse_clock_provider_as_flag()	 :for style A)
 snd_soc_daifmt_parse_clock_provider_as_phandl() :for style B)
 snd_soc_daifmt_parse_clock_provider_as_bitmap() :use with _from_bitmap

This means

 snd_soc_of_parse_daifmt() ==
	snd_soc_daifmt_parse_format() |
	snd_soc_daifmt_parse_clock_provider_as_flag()

Each buffer type has now callbacks in the struct snd_malloc_ops, and
the common helper functions call those ops accordingly.  The former
inline code that is specific to SG-buffer is moved into the local
sgbuf.c, and we can simplify the PCM code without details of memory
handling.

47271b1b98 ALSA: pcm: add snd_pcm_period_elapsed() variant without acquiring lock of PCM substream
Current implementation of ALSA PCM core has a kernel API,
snd_pcm_period_elapsed(), for drivers to queue event to awaken processes
from waiting for available frames. The function voluntarily acquires lock
of PCM substream, therefore it is not called in process context for any
PCM operation since the lock is already acquired.

It is convenient for packet-oriented driver, at least for drivers to audio
and music unit in IEEE 1394 bus. The drivers are allowed by Linux
FireWire subsystem to process isochronous packets queued till recent
isochronous cycle in process context in any time.

This commit adds snd_pcm_period_elapsed() variant,
snd_pcm_period_elapsed_without_lock(), for drivers to queue the event in
the process context.

ASoC: soc-core: add snd_soc_runtime_get_dai_fmt()
ASoC is using dai_link which specify DAI format (= dai_link->dai_fmt),
and it is selected by "Sound Card" driver in corrent implementation.
In other words, Sound Card *needs* to setup it.
But, it should be possible to automatically selected from CPU and
Codec driver settings.

This patch adds new .auto_selectable_formats support
at snd_soc_dai_ops.

By this patch, dai_fmt can be automatically selected from each
driver if both CPU / Codec driver had it.
Automatically selectable *field* is depends on each drivers.

For example, some driver want to select format "automatically",
but want to select other fields "manually", because of complex limitation.
Or other example, in case of both CPU and Codec are possible to be
clock provider, but the quality was different.
In these case, user need/want to *manually* select each fields
from Sound Card driver.

This .auto_selectable_formats can set priority.
For example, no limitaion format can be HI priority,
supported but has picky limitation format can be next priority, etc.

It uses Sound Card specified fields preferentially, and try to select
non-specific fields from CPU and Codec driver automatically
if all drivers have .auto_selectable_formats.

In other words, we can select all dai_fmt via Sound Card driver
same as before.

e94fdbd7b2 ALSA: control: Track in-flight control read/write/tlv accesses
Although the power state check is performed in various places (e.g. at
the entrance of quite a few ioctls), there can be still some pending
tasks that already went into the ioctl handler or other ops, and those
may access the hardware even after the power state check.  For
example, kcontrol access ioctl paths that call info/get/put callbacks
may update the hardware registers.  If a system wants to assure the
free from such hw access (like the case of PCI rescan feature we're
going to implement in future), this situation must be avoided, and we
have to sync such in-flight tasks finishing beforehand.

For that purpose, this patch introduces a few new things in core code:
- A refcount, power_ref, and a wait queue, power_ref_sleep, to the
  card object
- A few new helpers, snd_power_ref(), snd_power_unref(),
  snd_power_ref_and_wait(), and snd_power_sync_ref()

In the code paths that call kctl info/read/write/tlv ops, we check the
power state with the newly introduced snd_power_ref_and_wait().  This
function also takes the card.power_ref refcount for tracking this
in-flight task.  Once after the access finishes, snd_power_unref() is
called to released the refcount in return.  So the driver can sync via
snd_power_sync_ref() assuring that all in-flight tasks have been
finished.

As of this patch, snd_power_sync_ref() is called only at
snd_card_disconnect(), but it'll be used in other places in future.

Note that atomic_t is used for power_ref intentionally instead of
refcount_t.  It's because of the design of refcount_t type; refcount_t
cannot be zero-based, and it cannot do dec_and_test() call for
multiple times, hence it's not suitable for our purpose.

Also, this patch changes snd_power_wait() to accept only
SNDRV_CTL_POWER_D0, which is the only value that makes sense.

08fdced60c ALSA: rawmidi: Add framing mode
This commit adds a new framing mode that frames all MIDI data into
32-byte frames with a timestamp.

The main benefit is that we can get accurate timestamps even if
userspace wakeup and processing is not immediate.

Testing on a Celeron N3150 with this mode has a max jitter of 2.8 ms,
compared to the in-kernel seq implementation which has a max jitter
of 5 ms during idle and much worse when running scheduler stress tests
in parallel.

ASoC: topology: Add support for multiple kcontrol types to a widget
Current dapm widget has a single variable to describe its kcontrol's
type. As there can be many kcontrols in one widget it is inherently
presumed that the types are the same.

Lately there has been use cases where different types of kcontrols would
be needed for a single widget. Thus add pointer to dapm widget to hold
an array for different kcontrol types and modify the kcontrol creation
to operate in a loop based on individual kcontrol type.

Change control creation and deletion to use individual kcontrol types in
SOF driver. This is done in the same patch for not breaking bisect. SOF
driver is also currently the only one using the dapm widget
kcontrol_type.

ASoC: simple-card-utils: share dummy DAI and reduce memory
Current simple-card / audio-graph creates 1xCPU + 1xCodec + 1xPlatform
for all dai_link, but some of them is not needed.
For example Platform is not needed for DPCM BE case.
Moreover, we can share snd-soc-dummy DAI for CPU-dummy / dummy-Codec
in DPCM.

This patch adds dummy DAI and share it when DPCM case,
I beliave it can contribute to reduce memory.

By this patch, CPU-dummy / dummy-CPU are set at asoc_simple_init_priv(),
thus, its settings are no longer needed at DPCM detecting timing
on simple-card / audio-graph.
Moreover, we can remove triky Platform settings code for DPCM BE,
because un-needed Platform is not created.

66c6d1ef86 ALSA: control: Add memory consumption limit to user controls
ALSA control interface allows users to add arbitrary control elements
(called "user controls" or "user elements"), and its resource usage is
limited just by the max number of control sets (currently 32).  This
limit, however, is quite loose: each allocation of control set may
have 1028 elements, and each element may have up to 512 bytes (ILP32) or
1024 bytes (LP64) of value data. Moreover, each control set may contain
the enum strings and TLV data, which can be up to 64kB and 128kB,
respectively.  Totally, the whole memory consumption may go over 38MB --
it's quite large, and we'd rather like to reduce the size.

OTOH, there have been other requests even to increase the max number
of user elements; e.g. ALSA firewire stack require the more user
controls, hence we want to raise the bar, too.

For satisfying both requirements, this patch changes the management of
user controls: instead of setting the upper limit of the number of
user controls, we check the actual memory allocation size and set the
upper limit of the total allocation in bytes.  As long as the memory
consumption stays below the limit, more user controls are allowed than
the current limit 32. At the same time, we set the lower limit (8MB)
as default than the current theoretical limit, in order to lower the
risk of DoS.

As a compromise for lowering the default limit, now the actual memory
limit is defined as a module option, 'max_user_ctl_alloc_size', so that
user can increase/decrease the limit if really needed, too.

ad858508fd ALSA: control - add generic LED API
This patchset tries to resolve the diversity in the audio LED
 control among the ALSA drivers. A new control layer registration
 is introduced which allows to run additional operations on
 top of the elementary ALSA sound controls.
 
 A new control access group (three bits in the access flags)
 was introduced to carry the LED group information for
 the sound controls. The low-level sound drivers can just
 mark those controls using this access group. This information
 is not exported to the user space, but user space can
 manage the LED sound control associations through sysfs
 (last patch) per Mark's request. It makes things fully
 configurable in the kernel and user space (UCM).
 
 The actual state ('route') evaluation is really easy
 (the minimal value check for all channels / controls / cards).
 If there's more complicated logic for a given hardware,
 the card driver may eventually export a new read-only
 sound control for the LED group and do the logic itself.
 
 The new LED trigger control code is completely separated
 and possibly optional (there's no symbol dependency).
 The full code separation allows eventually to move this
 LED trigger control to the user space in future.
 Actually it replaces the already present functionality
 in the kernel space (HDA drivers) and allows a quick adoption
 for the recent hardware (ASoC codecs including SoundWire).
 
 snd_ctl_led            24576  0
 
 The sound driver implementation is really easy:
 
 1) call snd_ctl_led_request() when control LED layer should be
    automatically activated
    / it calls module_request("snd-ctl-led") on demand /
 2) mark all related kcontrols with
         SNDRV_CTL_ELEM_ACCESS_SPK_LED or
         SNDRV_CTL_ELEM_ACCESS_MIC_LED

ALSA: control - add generic LED API

This patchset tries to resolve the diversity in the audio LED
control among the ALSA drivers. A new control layer registration
is introduced which allows to run additional operations on
top of the elementary ALSA sound controls.

A new control access group (three bits in the access flags)
was introduced to carry the LED group information for
the sound controls. The low-level sound drivers can just
mark those controls using this access group. This information
is not exported to the user space, but user space can
manage the LED sound control associations through sysfs
(last patch) per Mark's request. It makes things fully
configurable in the kernel and user space (UCM).

The actual state ('route') evaluation is really easy
(the minimal value check for all channels / controls / cards).
If there's more complicated logic for a given hardware,
the card driver may eventually export a new read-only
sound control for the LED group and do the logic itself.

The new LED trigger control code is completely separated
and possibly optional (there's no symbol dependency).
The full code separation allows eventually to move this
LED trigger control to the user space in future.
Actually it replaces the already present functionality
in the kernel space (HDA drivers) and allows a quick adoption
for the recent hardware (ASoC codecs including SoundWire).

snd_ctl_led            24576  0

The sound driver implementation is really easy:

1) call snd_ctl_led_request() when control LED layer should be
   automatically activated
   / it calls module_request("snd-ctl-led") on demand /
2) mark all related kcontrols with
        SNDRV_CTL_ELEM_ACCESS_SPK_LED or
        SNDRV_CTL_ELEM_ACCESS_MIC_LED

22d8de62f1 ALSA: control - add generic LED trigger module as the new control layer
The recent laptops have usually two LEDs assigned to reflect
the speaker and microphone mute state. This implementation
adds a tiny layer on top of the control API which calculates
the state for those LEDs using the driver callbacks.

Two new access flags are introduced to describe the controls
which affects the audio path settings (an easy code change
for drivers).

The LED resource can be shared with multiple sound cards with
this code. The user space controls may be added to the state
chain on demand, too.

This code should replace the LED code in the HDA driver and
add a possibility to easy extend the other drivers (ASoC
codecs etc.).

Merge series "Add audio driver base on rpmsg on i.MX platform" from Shengjiu Wang <shengjiu.wang@nxp.com>:
On Asymmetric multiprocessor, there is Cortex-A core and Cortex-M core,
Linux is running on A core, RTOS is running on M core.
The audio hardware device can be controlled by Cortex-M device,
So audio playback/capture can be handled by M core.

Rpmsg is the interface for sending and receiving msg to and from M
core, that we can create a virtual sound on Cortex-A core side.

A core will tell the Cortex-M core sound format/rate/channel,
where is the data buffer, what is the period size, when to start,
when to stop and when suspend or resume happen, each of this behavior
there is defined rpmsg command.

Especially we designed the low power audio case, that is to
allocate a large buffer and fill the data, then Cortex-A core can go
to sleep mode, Cortex-M core continue to play the sound, when the
buffer is consumed, Cortex-M core will trigger the Cortex-A core to
wakeup to fill data.

changes in v5:
- remove unneeded property in binding doc and driver
- update binding doc according to Rob's comments.
- Fix link issue reported by kernel test robot

changes in v4:
- remove the sound card node, merge the property to cpu dai node
  according to Rob's comments.
- sound card device will be registered by cpu dai driver.
- Fix do_div issue reported by kernel test robot

changes in v3:
- add local refcount for clk enablement in hw_params()
- update the document according Rob's comments

The differences are

	3) Do soc_pcm_hw_free() if it was not !OPENed and !HW_FREEed,

We can share same code by

9b838a3c32 ALSA/ASoC/SOF/SoundWire: fix Kconfig issues
In January, Intel kbuild bot and Arnd Bergmann reported multiple
 issues with randconfig. This patchset builds on Arnd's suggestions to
 
 a) expose ACPI and PCI devices in separate modules, while sof-acpi-dev
 and sof-pci-dev become helpers. This will result in minor changes
 required for developers/testers, i.e. modprobe snd-sof-pci will no
 longer result in a probe. The SOF CI was already updated to deal with
 this module dependency change and introduction of new modules.
 
 b) Fix SOF/SoundWire/DSP_config dependencies by moving the code
 required to detect SoundWire presence in ACPI tables to sound/hda.

ALSA/ASoC/SOF/SoundWire: fix Kconfig issues

In January, Intel kbuild bot and Arnd Bergmann reported multiple
issues with randconfig. This patchset builds on Arnd's suggestions to

a) expose ACPI and PCI devices in separate modules, while sof-acpi-dev
and sof-pci-dev become helpers. This will result in minor changes
required for developers/testers, i.e. modprobe snd-sof-pci will no
longer result in a probe. The SOF CI was already updated to deal with
this module dependency change and introduction of new modules.

b) Fix SOF/SoundWire/DSP_config dependencies by moving the code
required to detect SoundWire presence in ACPI tables to sound/hda.

To change the module dependencies and simplify Kconfigs, we need to
introduce new driver names (sof-audio-acpi-intel-byt and
sof-audio-acpi-intel-bdw), and move from an exact string match to a
partial one.

a864e8f159 ALSA: hda: intel-nhlt: verify config type
Multiple bug reports report issues with the SOF and SST drivers when
dealing with single microphone cases.

We currently read the DMIC array information unconditionally but we
don't check that the configuration type is actually a mic array.

When the DMIC link does not rely on a mic array configuration, the
recommendation is to check the format information to infer the maximum
number of channels, and map this to the number of microphones.

This leaves a potential for a mismatch between actual microphones
available in hardware and what the ACPI table contains, but we have no
other source of information.

Note that single microphone configurations can alternatively be
handled with a 'mic array' configuration along with a 'vendor-defined'
geometry.

f9e5fd1b66 ALSA: hda: add link_power op to hdac_bus_ops
The extended HDA bus (hdac_ext) provides interfaces for more
fine-grained control of individual links than what plain HDA
provides for. Links can be powered off when they are not used and if
all links are released, controller can shut down the command DMA.

These interfaces are currently not used by common HDA codec drivers.
When a HDA codec is runtime suspended, it calls snd_hdac_codec_link_down(),
but there is no link to the HDA extended bus, and on controller side
the links are shut down only when all codecs are suspended.

This patch adds link_power() to hdac_bus ops. Controllers using the HDA
extended core, can use this to plug in snd_hdac_ext_bus_link_power() to
implement more fine-grained control of link power.

No change is needed for plain HDA controllers nor to existing HDA
codec drivers.

2d670ea2bd ALSA: jack: implement software jack injection via debugfs
This change adds audio jack injection feature through debugfs, with
this feature, we could validate alsa userspace changes by injecting
plugin or plugout events to the non-phantom audio jacks.

With this change, the sound core will build the folders
$debugfs_mount_dir/sound/cardN if SND_DEBUG and DEBUG_FS are enabled.
And if users also enable the SND_JACK_INJECTION_DEBUG, the jack
injection nodes will be built in the folder cardN like below:

$tree $debugfs_mount_dir/sound
$debugfs_mount_dir/sound

        ├── mask_bits
        ├── status
        ├── sw_inject_enable
        └── type

The nodes kctl_id, mask_bits, status and type are read-only, users
could check jack or jack_kctl's information through them.

The nodes sw_inject_enable and jackin_inject are directly used for
injection. The sw_inject_enable is read-write, users could check if
software injection is enabled or not on this jack, and users could
echo 1 or 0 to enable or disable software injection on this jack. Once
the injection is enabled, the jack will not change by hardware events
anymore, once the injection is disabled, the jack will restore the
last reported hardware events to the jack. The jackin_inject is
write-only, if the injection is enabled, users could echo 1 or 0 to
this node to inject plugin or plugout events to this jack.

For the detailed usage information on these nodes, please refer to
Documentation/sound/designs/jack-injection.rst.

ASoC: soc-component: add snd_soc_component_read/write_field()
It's often the case that we would write or read a particular field
in register. With the current soc_component apis, reading a particular
field in register would involve first read the register and then
perform shift operations.

Ex:
to read from a field mask of 0xf0

	val = snd_soc_component_read(component, reg);
	field = ((val & 0xf0) >> 0x4);

This is sometimes prone to errors and code become less readable!

With this new api we could just do
	field = snd_soc_component_read_field(component, reg, 0xf0);

this makes it bit simple, easy to write and less error prone!

This also applies to writing!

There are various places in kernel which provides such field interfaces
however soc_component seems to be missing this.

This patch is inspired by FIELD_GET/FIELD_PREP macros in include/linux/bitfield.h

23b53d4417 ALSA: pcm: One more dependency for hw constraints
The fix for a long-standing USB-audio bug required one more dependency
variable to be added to the hw constraints.  Unfortunately I didn't
realize at debugging that the new addition may result in the overflow
of the dependency array of each snd_pcm_hw_rule (up to three plus a
sentinel), because USB-audio driver adds one more dependency only for
a certain device and bus, hence it works as is for many devices.  But
in a bad case, a simple open always results in -EINVAL (with kernel
WARNING if CONFIG_SND_DEBUG is set) no matter what is passed.

Since the dependencies are real and unavoidable (USB-audio restricts
the hw_params per looping over the format/rate/channels combos), the
only good solution seems to raise the bar for one more dependency for
snd_pcm_hw_rule -- so does this patch: now the hw constraint
dependencies can be up to four.

 - Support for some basic DPCM systems in the audio graph card from
   Sameer Pujar.
 - Remove some old pre-DT Freescale drivers for platforms that are now
   DT only.
 - Move selection of which Intel DSP implementation to use to boot time
   rather than requiring it to be selected at build time.
 - Support for Allwinner H6 I2S, Analog Devices ADAU1372, Intel
   Alderlake-S, GMediatek MT8192, NXP i.MX HDMI and XCVR, Realtek RT715,
   Qualcomm SM8250 and simple GPIO based muxes.

ASoC: soc-pcm: care trigger rollback
soc_pcm_trigger() calls DAI/Component/Link trigger,
but some of them might be failed.

	static int soc_pcm_trigger(...)
	{
		...
		switch (cmd) {
		case SNDRV_PCM_TRIGGER_START:
		case SNDRV_PCM_TRIGGER_RESUME:
		case SNDRV_PCM_TRIGGER_PAUSE_RELEASE:
			ret = snd_soc_link_trigger(substream, cmd);
			if (ret < 0)
				break;

(*)			ret = snd_soc_pcm_component_trigger(substream, cmd);
			if (ret < 0)
				break;

			ret = snd_soc_pcm_dai_trigger(substream, cmd);
			break;
		case SNDRV_PCM_TRIGGER_STOP:
		case SNDRV_PCM_TRIGGER_SUSPEND:
		case SNDRV_PCM_TRIGGER_PAUSE_PUSH:
			ret = snd_soc_pcm_dai_trigger(substream, cmd);
			if (ret < 0)
				break;

			ret = snd_soc_pcm_component_trigger(substream, cmd);
			if (ret < 0)
				break;

			ret = snd_soc_link_trigger(substream, cmd);
			break;
		}
		...
	}

For example, if soc_pcm_trigger() failed at (*) point,
we need to rollback previous succeeded trigger.

This patch adds trigger mark for DAI/Component/Link,
and do STOP if START/RESUME/PAUSE_RELEASE were failed.

Because it need to use new rollback parameter,
we need to modify DAI/Component/Link trigger functions in the same time.

ASoC: SOF: trace: Add runtime trace filtering mechanism
The "filter" debugfs file defines the log levels used by
the firmware and reported by sof-logger.

The file contains the formatted entry list, where each entry
follows the following syntax in plain text:
log_level uuid_id pipe_id comp_id;

This file may be updated by userspace applications such sof-logger,
or directly by the user during debugging process.

An unused (wildcard) pipe_id or comp_id value should be set to -1,
uuid_id is hexadecimal value, so when unused then should be set to 0.

When the file is modified, an IPC command is sent to FW with new
trace levels for selected components in filter elements list.

Merge series "ASoC: SOF: Intel: fix ICL boot sequence" from Kai Vehmanen <kai.vehmanen@linux.intel.com>:
Series introducing a modified boot sequence for the Intel Ice Lake
platform. While no bugs are currently open for this, the current
DSP boot implementation does not follow the full programming sequence.

This patchset is the first instance where SOF driver uses data in
the extended manifest (part of the firmware binary), to influence
the boot process. IPC cannot be used to get this information, as it
is already needed for early boot.

This change is backwards compatible with old firmware versions,
where extended manifest is not available.

9be9f2d3d0 ALSA: compress: allow pause and resume during draining
With a stream with low bitrate, user can't pause or resume the stream
near the end of the stream because current ALSA doesn't allow it.
If the stream has very low bitrate enough to store whole stream into
the buffer, user can't do anything except stop the stream and then
restart it from the first because most of applications call draining
after sending last frame to the kernel.
If pause, resume are allowed during draining, user experience can be
enhanced.
To prevent malfunction in HW drivers which don't support pause
during draining, pause during draining will only work if HW driver
enable this feature explicitly by calling
snd_compr_use_pause_in_draining().

soc_compr_open() does rollback when failed (A),

 ^	machine_err:

The difference is
soc_compr_free()  is for all dai/component/substream,
rollback          is for succeeded part only.

This kind of duplicated code can be a hotbed of bugs,
thus, we want to share soc_compr_free() and rollback.
	1) snd_soc_dai_compr_startup/shutdown()
	2) snd_soc_component_compr_open/free()
=>	3) snd_soc_link_compr_startup/shutdown()

This patch is for 3) snd_soc_link_compr_startup/shutdown()
and adds new cstream mark.
It will mark cstream when startup() was suceeded.
If rollback happen *after* that, it will check rollback flag
and marked cstream.

It cares *previous* startup() only now,
but we might want to check *whole* marked cstream in the future.
This patch is using macro so that it can be easily adjust to it.

ASoC: soc-acpi: add helper to identify parent driver.
Intel machine drivers are used by parent platform drivers based on
closed-source firmware (Atom/SST and catpt) and SOF-based ones.

In some cases for ACPI-based platforms, the behavior of machine
drivers needs to be modified depending on the parent type, typically
for card names and power management.

An initial solution based on passing a boolean flag as a platform
device parameter was tested earlier. Since it looked overkill, this
patch suggests instead a simple string comparison to identify an SOF
parent device/driver.

The "legacy" option supported for HDaudio has no meaning here and will
be ignored.

The 'SST' driver based on closed-source firmware has the priority to
avoid any impact on users, and the choice to use SOF is strictly
opt-in. This may change at some point when the 'SST' driver is
deprecated on Baytrail/Cherrytrail.

Merge series "ASoC: use inclusive language for bclk/fsync/topology" from Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>:
The SOF (Sound Open Firmware) tree contains a lot of references in
topology files to 'codec_slave'/'codec_master' terms, which in turn
come from alsa-lib and ALSA/ASoC topology support at the kernel
level. These terms are no longer compatible with the guidelines
adopted by the kernel community [1], standard organizations, and need
to change in backwards-compatible ways.

The main/secondary terms typically suggested in guidelines don't mean
anything for clocks, this patchset suggests instead the use of
'provider' and 'consumer' terms, with the 'codec' prefix kept to make
it clear that the codec is the reference. The CM/CS suffixes are also
replaced by CP/CC.

It can be argued that the change of suffix is invasive, but finding a
replacement that keeps the M and S shortcuts has proven difficult in
quite a few contexts.

The previous definitions are kept for backwards-compatibility so this
change should not have any functional impact. It is suggested that new
contributions only use the new terms but there is no requirement to
transition immediately to the new definitions for existing code. Intel
will however update all its past contributions related to bit
clock/frame sync configurations immediately.

This patchset contains the kernel changes only, the alsa-lib changes
were shared separately.

Feedback welcome

ASoC: audio-graph: Expose helpers from audio graph
This commit exposes following functions which can be used by a sound
card driver based on generic audio graph driver. Idea is vendors can
have a thin driver and re-use common stuff from audio graph driver.

 - graph_card_probe()
 - graph_parse_of()

In doing so a new header file is added for above. The graph_probe()
function is simplified by moving more common stuff to graph_parse_of().

ASoC: audio-graph: Expose new members for asoc_simple_priv
Add new members in struct 'asoc_simple_priv'. Idea is to leverage
simple or graph card driver as much as possible and vendor can
maintain a thin driver to control the behavior by populating these
newly exposed members.

Following are the members added in 'asoc_simple_priv':

  - 'ops' struct: In some cases SoC vendor drivers may want to
    implement 'snd_soc_ops' callbacks differently. In such cases
    custom callbacks would be used.

  - 'force_dpcm' flag: Right now simple or graph card drivers
    detect DAI links as DPCM links if:

      * The dpcm_selectable is set AND
      * Codec is connected to multiple CPU endpoints or aconvert
        property is used for rate/channels.

    So there is no way to directly specify usage of DPCM alone. So a
    flag is exposed to mark all links as DPCM. Vendor driver can
    set this if required.

  - 'dpcm_selectable': Currently simple or audio graph drivers
    provide a way to enable this for specific compatibles. However
    vendor driver may want to define some additional info. Thus
    expose this variable where vendor drivers can set this if
    required.

Audio graph driver is updated to consider above flags or callbacks.
Subsequent patches in the series illustrate usage for above.

ASoC: soc-pcm: Get all BEs along DAPM path
dpcm_end_walk_at_be() stops the graph walk when first BE is found for
the given FE component. In a component model we may want to connect
multiple DAIs from different components. A new flag is introduced in
'snd_soc_card', which when set allows DAI/component chaining. Later
PCM operations can be called for all these listed components for a
valid DAPM path.

ASoC: soc-pcm: add soc_pcm_hw_clean() and call it from soc_pcm_hw_params/free()
soc_pcm_hw_params() does rollback when failed (A),
but, it is almost same as soc_pcm_hw_free().

	static int soc_pcm_hw_params(xxx)
	{
		...
		if (ret < 0)
			goto xxx_err;
		...
		return ret;

 ^	component_err:
 |		...
 |	interface_err:
(A)		...
 |	codec_err:
 |		...
 v		return ret;
	}

The difference is
soc_pcm_hw_free() is for all dai/component/substream,
rollback          is for succeeded part only.

This kind of duplicated code can be a hotbed of bugs,
thus, we want to share soc_pcm_hw_free() and rollback.

Now, soc_pcm_hw_params/free() are handling
	1) snd_soc_link_hw_params/free()
	2) snd_soc_pcm_component_hw_params/free()
	3) snd_soc_dai_hw_params/free()

Now, 1) to 3) are handled.
This patch adds new soc_pcm_hw_clean() and call it from
soc_pcm_hw_params() as rollback, and from soc_pcm_hw_free() as
normal close handler.

Other difference is that soc_pcm_hw_free() handles digital mute
if it was last user. Rollback also handles it by this patch.

	1) snd_soc_link_hw_params/free()
	2) snd_soc_pcm_component_hw_params/free()
=>	3) snd_soc_dai_hw_params/free()

This patch is for 3) snd_soc_dai_hw_params/free().

The idea of having bit-flag or counter is not enough for this purpose.
For example if one DAI is used for 2xPlaybacks for some reasons,
and if 1st Playback was succeeded but 2nd Playback was failed,
2nd Playback rollback doesn't need to call shutdown.
But it has succeeded bit-flag or counter via 1st Playback,
thus, 2nd Playback rollback will call unneeded shutdown.
And 1st Playback's necessary shutdown will not be called,
because bit-flag or counter was cleared by wrong 2nd Playback rollback.

To avoid such case, this patch marks substream pointer when hw_params() was
succeeded. If rollback needed, it will check rollback flag and marked
substream pointer.

One note here is that it cares *previous* hw_params() only now,
but we might want to check *whole* marked substream in the future.
This patch is using macro named "push/pop", so that it can be easily
update.

ASoC: soc-link: add mark for snd_soc_link_hw_params/free()
soc_pcm_hw_params() does rollback when failed (A),
but, it is almost same as soc_pcm_hw_free().

	static int soc_pcm_hw_params(xxx)
	{
		...
		if (ret < 0)
			goto xxx_err;
		...
		return ret;

 ^	component_err:
 |		...
 |	interface_err:
(A)		...
 |	codec_err:
 |		...
 v		return ret;
	}

The difference is
soc_pcm_hw_free() is for all dai/component/substream,
rollback          is for succeeded part only.

This kind of duplicated code can be a hotbed of bugs,
thus, we want to share soc_pcm_hw_free() and rollback.

Now, soc_pcm_hw_params/free() are handling
=>	1) snd_soc_link_hw_params/free()
	2) snd_soc_pcm_component_hw_params/free()
	3) snd_soc_dai_hw_params/free()

This patch is for 1) snd_soc_link_hw_params/free().

The idea of having bit-flag or counter is not enough for this purpose.
For example if one DAI is used for 2xPlaybacks for some reasons,
and if 1st Playback was succeeded but 2nd Playback was failed,
2nd Playback rollback doesn't need to call shutdown.
But it has succeeded bit-flag or counter via 1st Playback,
thus, 2nd Playback rollback will call unneeded shutdown.
And 1st Playback's necessary shutdown will not be called,
because bit-flag or counter was cleared by wrong 2nd Playback rollback.

To avoid such case, this patch marks substream pointer when hw_params() was
succeeded. If rollback needed, it will check rollback flag and marked
substream pointer.

One note here ist that it cares *previous* hw_params() only now,
but we might want to check *whole* marked substream in the future.
This patch is using macro named "push/pop", so that it can be easily
update.

a6e7d0a4bd ALSA: hda: fix jack detection with Realtek codecs when in D3
In case HDA controller becomes active, but codec is runtime suspended,
jack detection is not successful and no interrupt is raised. This has
been observed with multiple Realtek codecs and HDA controllers from
different vendors. Bug does not occur if both codec and controller are
active, or both are in suspend. Bug can be easily hit on desktop systems
with no built-in speaker.

The problem can be fixed by powering up the codec once after every
controller runtime resume. Even if codec goes back to suspend later, the
jack detection will continue to work. Add a flag to 'hda_codec' to
describe codecs that require this flow from the controller driver.
Modify __azx_runtime_resume() to use pm_request_resume() to make the
intent clearer.

Mark all Realtek codecs with the new forced_resume flag.

ASoC: Intel: add codec name prefix to ACPI machine description
The current SOF machine driver adds a name prefix for each codec,
mainly to differentiate ALSA controls for left and right amplifiers.

This is a good idea, but the machine driver duplicates some of the
information that already exists in ACPI descriptors, so add those
prefixes there. Follow-up patches will make use of the information
encoded in these tables and remove duplication.

ASoC: hdac: make SOF HDA codec driver probe deterministic
To provide backward compatibility to older systems, the SOF HDA driver
allows user to specify which HDMI codec driver to use at runtime via
kernel parameter. This mechanism has a subtle flaw in that it assumes
the codec drivers not to be loaded when the SOF PCI driver is loaded.

The problem is rooted in use of the hdev->type field.
snd_hdac_ext_bus_device_init() initializes this field to HDA_DEV_ASOC.
This signals the HDA core that ASoC drivers should be considered in
driver matching (hda_bus_match()). The SOF and SST drivers continue by
overriding this field to HDA_DEV_LEGACY and proceeding to load driver
modules with request_module(). Correct drivers will get loaded and
attached.

If however the codec drivers are already loaded when
snd_hdac_ext_bus_device_init() is called, the matching will not work as
expected as device type is still set to HDA_DEV_ASOC. Specifically if
hdac-hdmi is attached when machine driver is configured to use hdac-hda,
this leads to out-of-bounds memory access in
hda_dsp_hdmi_build_controls().

Fix the issue by adding codec type as a parameter to
snd_hdac_ext_bus_device_init() and ensuring type is set correctly from
the start.
