Mengdong Lin eea3dd4f12 ASoC: topology: Only free TLV for volume mixers of a widget
This patch will check the type of embedded controls for a widget, and
only free the TLV of volume mixers. Bytes controls don't have TLV.

Just free the private value which is used as struct soc_mixer_control
for volume mixers or soc_bytes_ext for bytes controls. No need to cast
to these types before freeing it.

Richard Fitzgerald 1b4d9c2219 ASoC: core: Add component pin control functions
It's often the case that a codec driver will need to control its
own pins. However, if a name_prefix has been applied to this codec it
must be included in the name passed to any of the snd_soc_dapm_x_pin()
functions.

The behaviour of the existing pin control functions is reasonable, since
you may want to search for a fully-specified name within the scope of an
entire card. This means that we can't apply the prefix in these functions
because it will break card-scope searches.

Constructing a prefixed string "manually" in codec drivers leads to a lot
of repetition of the same code.

To make this tidier in codec drivers this patch adds a new set of
equivalent functions that take a struct snd_soc_component instead of a
dapm context and automatically add the component's name_prefix to the
given name. This makes it a simple change in codec drivers to be
prefix-safe.

The new functions are not quite trivial enough to be inlines and the
compiler won't be able to compile-away any part of them.

Although it looks somewhat inefficient to have to allocate a temporary
buffer and combine strings, the current design of the widget list
doesn't lend itself to a more optimized implementation - it's a single
list of all widgets on a card and is searched linearly for a matching
string. As pin state changes are generally low-frequency events it's
unlikely to be a significant issue - at least not enough to rewrite the
widget list handling just for this.

Takashi Iwai aeaa6203b6 ALSA: emu10k1: Use workqueue instead of kthread for emu1010 fw polling
This patch is a cleanup of EMU1010 dock probing code in emu10k1 driver
to use work instead of kthread in a loop.  The work is lighter and
easier to control than kthread, in general.

Instead of a loop with the explicit sleep, we do simply
delayed-schedule the work.  At suspend/resume callbacks, the work is
canceled and restarted, respectively.

Define the API to find an existing DAI link of the soc card by matching
the ID, name and stream name.

Some cards may use unique ID for each DAI link, so matching ID is enough,
and name or stream name are not necessary. But user need to specify name
or stream name as well if not sure whether link ID is unique since most
cards use 0 as the default link ID.

Topology can use this API to find an existing BE link and configure it.

Takashi Sakamoto 318824d3d0 ALSA: control: cage TLV_DB_RANGE_HEAD in kernel land because it was obsoleted
In commit bf1d1c9b61 ("ALSA: tlv: add DECLARE_TLV_DB_RANGE()"), the new
macro was added so that "dB range information can be specified without
having to count the items manually for TLV_DB_RANGE_HEAD()". In short,
TLV_DB_RANGE_HEAD macro was obsoleted.

In commit 46e860f768 ("ALSA: rename TLV-related macros so that they're
friendly to user applications"), TLV-related macros are exposed for
applications in user land to get content of data structured by
Type/Length/Value shape. The commit managed to expose TLV-related macros
as many as possible, while obsoleted TLV_DB_RANGE_HEAD() was included to
the list of exposed macros.

This situation brings some confusions to application developers because
they might think all exposed macros have their own purpose and useful for
applications.

For the reason, this commit moves TLV_DB_RANGE_HEAD macro from UAPI header
to a header for kernel land, again. The above commit is done within the
same development period for kernel 4.9, thus not published yet. This

Pandiyan, Dhinakaran f931894194 drm/i915/dp: DP audio API changes for MST
DP MST provides the capability to send multiple video and audio streams
through a single port. This requires the API's between i915 and audio
drivers to distinguish between multiple audio capable displays that can be
connected to a port. Currently only the port identity is shared in the
APIs. This patch adds support for MST with an additional parameter
'int pipe'. The existing parameter 'port' does not change it's meaning.

pipe =
	MST	: display pipe that the stream originates from
	Non-MST	: -1

Affected APIs:
struct i915_audio_component_ops
-       int (*sync_audio_rate)(struct device *, int port, int rate);
+	int (*sync_audio_rate)(struct device *, int port, int pipe,
+	     int rate);

-       int (*get_eld)(struct device *, int port, bool *enabled,
-                       unsigned char *buf, int max_bytes);
+       int (*get_eld)(struct device *, int port, int pipe,
+		       bool *enabled, unsigned char *buf, int max_bytes);

struct i915_audio_component_audio_ops
-       void (*pin_eld_notify)(void *audio_ptr, int port);
+       void (*pin_eld_notify)(void *audio_ptr, int port, int pipe);

This patch makes dummy changes in the audio drivers (thanks Libin) for
build to succeed. The audio side drivers will send the right 'pipe' values
for MST in patches that will follow.

v2:
Renamed the new API parameter from 'dev_id' to 'pipe'. (Jim, Ville)
Included Asoc driver API compatibility changes from Jeeja.
Added WARN_ON() for invalid pipe in get_saved_encoder(). (Takashi)
Added comment for av_enc_map[] definition. (Takashi)

v3:
Fixed logic error introduced while renaming 'dev_id' as 'pipe' (Ville)
Renamed get_saved_encoder() to get_saved_enc() to reduce line length

v4:
Rebased.
Parameter check for pipe < -1 values in get_saved_enc() (Ville)
Switched to for_each_pipe() in get_saved_enc() (Ville)
Renamed 'pipe' to 'dev_id' in audio side code (Takashi)

v5:
Included a comment for the dev_id arg. (Libin)

Takashi Sakamoto 46e860f768 ALSA: rename TLV-related macros so that they're friendly to user applications
In a previous commit, some macros newly appeared to UAPI header for TLV
packet. These macros have short names and they easily bring name conflist
to applications. The conflict can be avoided to rename them with a proper
prefix.

For this purpose, this commit renames these macros with prefix
'SNDRV_CTL_TLVD_'.

Takashi Sakamoto 398fa4db6c ALSA: control: move layout of TLV payload to UAPI header
In ALSA control interface, each element set can have threshold level
information. This information is transferred between drivers/applications,
in a shape of tlv packet. The layout of this packet is defined in
'uapi/sound/asound.h' (struct snd_ctl_tlv):

struct snd_ctl_tlv {
    unsigned int numid;
    unsigned int length;
    unsigned int tlv[0];
};

Data in the payload (struct snd_ctl_tlv.tlv) is expected to be filled
according to our own protocol. This protocol is described in
'include/sound/tlv.h'. A layout of the payload is expected as:

struct snd_ctl_tlv.tlv[0]: one of SNDRV_CTL_TLVT_XXX
struct snd_ctl_tlv.tlv[1]: Length of data
struct snd_ctl_tlv.tlv[2...]: data

Unfortunately, the macro is not exported to user land yet, thus
applications cannot get to know the protocol.

Additionally, ALSA control core has a feature called as 'user-defined'
element set. This allows applications to add/remove arbitrary element sets
with elements to control devices. Elements in the element set can be
operated by the same way as the ones added by in-kernel implementation.

For threshold level information of 'user-defined' element set, applications
need to register the information to an element set. However, as described
above, layout of the payload is closed in kernel land. This is quite
inconvenient, too.

This commit moves the protocol to UAPI header for TLV.

Kuninori Morimoto abd3147e69 ASoC: add new simple-card-utils.c
Current ALSA SoC has simple-card driver which is supporting both
platform and DT probe.
Now, some sound cards driver are created based on simple-card.
They have similar feature or function, but implemented separately
on each drivers. This is a waste of code.
OTOH, merging these driver into same driver is highly risk,
because it will be very difficult to keep compatibility.
More over, ALSA SoC want to have graph base of DT feature in the
future. Maybe it want to use simple-card like feature / function.
Because of these background, this patch creates simple-card
helper utils, and provides common function to each drivers.

Kuninori Morimoto efc9194bcf ASoC: hdmi-codec: callback function will be called with private data
Current hdmi-codec driver is assuming that it will be registered
from HDMI driver. Because of this assumption, each callback function
has struct device pointer which is parent device (= HDMI).
Then, it can use dev_get_drvdata() to get private data.

OTOH, on some SoC/HDMI case, SoC has VIDEO/SOUND and HDMI IPs.
This case, it needs SoC VIDEO, SoC SOUND and HDMI video, HDMI codec
driver. In DesignWare HDMI IP case, SoC VIDEO (= DRM/KMS) driver tries
to bind DesignWare HDMI video driver, and HDMI codec driver
(= hdmi-codec). This case, above "parent device" of HDMI codec driver
is DRM/KMS driver and its "device" already has private data.

And, from DT and ASoC CPU/Codec/Card binding point of view, HDMI codec
(= hdmi-codec) needs to have "parent device" (= DRM/KMS), otherwise,
it never detect sound card.

Because of these reasons, some driver can't use dev_get_drvdata() to
get private data on hdmi-codec driver. This patch add new void pointer
on hdmi_codec_pdata for private data, and callback function will be
called with it.

Charles Keepax a4f2d87c63 ALSA: compress: Add function to indicate the stream has gone bad
Currently, the avail IOCTL doesn't pass any error status, which
means typically on error it simply shows no data available. This
can lead to situations where user-space is waiting indefinitely
for data that will never come as the DSP has suffered an
unrecoverable error.

Add snd_compr_stop_error which end drivers can call to indicate
the stream has suffered an unrecoverable error and stop it. The
avail and poll IOCTLs are then updated to report if the stream is
in an error state to user-space. Allowing the error to propagate
out. Processing of the actual snd_compr_stop needs to be deferred
to a worker thread as the end driver may detect the errors during
an existing operation callback.

This patch introduces SOC_SINGLE_S8_TLV() macro for volume control
on chips which supports both negative and positive gains with sign
bit on a 8 bit register, Gain ranges from -128 to +127 with a
predefined step size.
Currently we only have support to DOUBLE_S8_TLV() which does not fit
for cases where we just have separate gain control register for each
channel.

One of the Qualcomm SOC msm8916 has such gain control register whose gain
range is from -38.4dB to +38.4dB with step size of 0.3dB.

Piotr Stankiewicz 6742064aef ASoC: dapm: support user-defined stop condition in dai_get_connected_widgets
Certain situations may warrant examining DAPM paths only to a certain
arbitrary point, as opposed to always following them to the end. For
instance, when establishing a connection between a front-end DAI link
and a back-end DAI link in a DPCM path, it does not make sense to walk
the DAPM graph beyond the first widget associated with a back-end link.

This patch introduces a mechanism which lets a user of
dai_get_connected_widgets supply a function which will be called for
every node during the graph walk. When invoked, this function can
execute arbitrary logic to decide whether the walk, given a DAPM widget
and walk direction, should be terminated at that point or continued
as normal.

Matthias Reichl 73fe01cfb3 ASoC: dmaengine_pcm: Add support for packed transfers
dmaengine_pcm currently only supports setups where FIFO reads/writes
correspond to exactly one sample, eg 16-bit sample data is transferred
via 16-bit FIFO accesses, 32-bit data via 32-bit accesses.

This patch adds support for setups with fixed width FIFOs where
multiple samples are packed into a larger word.

For example setups with a 32-bit wide FIFO register that expect
16-bit sample transfers to be done with the left+right sample data
packed into a 32-bit word.

Support for packed transfers is controlled via the
SND_DMAENGINE_PCM_DAI_FLAG_PACK flag in snd_dmaengine_dai_dma_data.flags

If this flag is set dmaengine_pcm doesn't put any restriction on the
supported formats and sets the DMA transfer width to undefined.

This means control over the constraints is now transferred to the DAI
driver and it's responsible to provide proper configuration and
check for possible corner cases that aren't handled by the ALSA core.

Takashi Iwai bb03ed2163 ALSA: hda - Update BCLK also at hotplug for i915 HSW/BDW
The recent bug report suggests that BCLK setup for i915 HSW/BDW needs
to be updated at each HDMI hotplug, not only at initialization and
resume.  That is, we need to update HSW_EM4 and HSW_EM5 registers at
ELD notification, too.  Otherwise the HDMI audio may be out of sync
and played in a wrong pitch.

However, the HDA codec driver has no access to the controller
registers, and currently the code managing these registers is in
hda_intel.c, i.e. local to the controller driver.  For allowing the
explicit BCLK update from the codec driver, as in this patch, the
former haswell_set_bclk() in hda_intel.c is moved to hdac_i915.c and
exposed as snd_hdac_i915_set_bclk().  This is called from both the HDA
controller driver and intel_pin_eld_notify() in HDMI codec driver.

Along with this change, snd_hdac_get_display_clk() gets dropped as
it's no longer used.

Takashi Iwai 3194ed4979 ALSA: hda - Fix possible race on regmap bypass flip
HD-audio driver uses regmap cache bypass feature for reading a raw
value without the cache.  But this is racy since both the cached and
the uncached reads may occur concurrently.  The former is done via the
normal control API access while the latter comes from the proc file
read.

Even though the regmap itself has the protection against the
concurrent accesses, the flag set/reset is done without the
protection, so it may lead to inconsistent state of bypass flag that
doesn't match with the current read and occasionally result in a
kernel WARNING like:
  WARNING: CPU: 3 PID: 2731 at drivers/base/regmap/regcache.c:499 regcache_cache_only+0x78/0x93

One way to work around such a problem is to wrap with a mutex.  But in
this case, the solution is simpler: for the uncached read, we just
skip the regmap and directly calls its accessor.  The verb execution
there is protected by itself, so basically it's safe to call
individually.

The existing TLV callback implementation copies all of the

With this patch, it parses the spk_alloc block as queried from

allocation entries from the cea channel speaker allocation table.
Thus the user can parse the TLV container to identify sink's

It shouldn't impact the behavior in AMD chipset, as this makes

Takashi Iwai fc4f000bf8 ALSA: hda - Fix unexpected resume through regmap code path
HD-audio driver has a mechanism to trigger the runtime resume
automatically at accessing the verbs.  This auto-resume, however,
causes the mutex deadlock when invoked from the regmap handler since
the regmap keeps the mutex while auto-resuming.  For avoiding that,
there is some tricky check in the HDA regmap handler to return -EAGAIN
error to back-off when the codec is powered down.  Then the caller of
regmap r/w will retry after properly turning on the codec power.

This works in most cases, but there seems a slight race between the
codec power check and the actual on-demand auto-resume trigger.  This
resulted in the lockdep splat, eventually leading to a real deadlock.

This patch tries to address the race window by getting the runtime PM
refcount at the check time using pm_runtime_get_if_in_use().  With
this call, we can keep the power on only when the codec has been
already turned on, and back off if not.

For keeping the code consistency, the code touching the runtime PM is
stored in hdac_device.c although it's used only locally in
hdac_regmap.c.

Takashi Iwai 473f414564 ALSA: hda - Loop interrupt handling until really cleared
Currently the interrupt handler of HD-audio driver assumes that no irq
update is needed while processing the irq.  But in reality, it has
been confirmed that the HW irq is issued even during the irq
handling.  Since we clear the irq status at the beginning, process the
interrupt, then exits from the handler, the lately issued interrupt is
left untouched without being properly processed.

This patch changes the interrupt handler code to loop over the
check-and-process.  The handler tries repeatedly as long as the IRQ
status are turned on, and either stream or CORB/RIRB is handled.

For checking the stream handling, snd_hdac_bus_handle_stream_irq()
returns a value indicating the stream indices bits.  Other than that,
the change is only in the irq handler itself.

Since the recent integration of kctl jack and input jack layers, we
can basically build the jack layer even without input devices.  That
is, the jack layer itself can be built with conditional to enable the

CONFIG_SND_JACK unconditionally.

For achieving it, this patch changes the following:
- A new Kconfig, CONFIG_SND_JACK_INPUT_DEV, was introduced to indicate
  whether the jack layer supports the input device,
- A few items in snd_jack struct and relevant codes are conditionally
  built upon CONFIG_SND_JACK_INPUT_DEV,
- The users of CONFIG_SND_JACK drop the messy dependency on
  CONFIG_INPUT.

This change also automagically fixes a potential bug in HD-audio
driver Arnd reported, where the NULL or uninitialized jack instance is

Mengdong Lin acfc7d46cd ASoC: topology: Add FE DAI links dynamically
Topology will also create FE DAI links dynamically from the PCM
objects. These links will be removed when the component is removed
and its topology info is unloaded.

The component driver can implement link_load/unload ops for extra
intialization (e.g. error check) and destruction.

Mengdong Lin 64527e8a35 ASoC: topology: Add FE DAIs dynamically
Topology will create FE DAIs dynamically from the PCM objects,
and register them to the component.

A PCM topoplogy object describes a FE DAI and DAI link. Later
patch will add FE DAI links as well.

Change tplg load ops for DAI:
- Only process a DAI.
- Pass the DAI driver pointer to the component driver for
  extra initialization.

In the former case, the reason is that virmidi has an open code
calling snd_rawmidi_transmit_ack() with the value calculated outside
the spinlock.   We may use snd_rawmidi_transmit() in a loop just for
consuming the input data, but even there, there is a race between
snd_rawmidi_transmit_peek() and snd_rawmidi_tranmit_ack().

Similarly in the latter case, it calls snd_rawmidi_transmit_peek() and
snd_rawmidi_tranmit_ack() separately without protection, so they are
racy as well.

The patch tries to address these issues by the following ways:
- Introduce the unlocked versions of snd_rawmidi_transmit_peek() and
  snd_rawmidi_transmit_ack() to be called inside the explicit lock.
- Rewrite snd_rawmidi_transmit() to be race-free (the former case).
- Make the split calls (the latter case) protected in the rawmidi spin
  lock.

Currently the info in /proc/interrupts doesn't allow to figure out which

Therefore add card details to the interrupt description.
With the patch the info in /proc/interrupts looks like this:

PCI-MSI 442368-edge      snd_hda_intel:card1
PCI-MSI 49152-edge      snd_hda_intel:card0

NOTE: this patch adds the new irq_descr field snd_card struct that is
filled automatically at a card object creation.  This can be used
generically for other drivers as well.  The changes for others will

Mengdong Lin f2ed6b0764 ASoC: Make aux_dev more like a generic component
aux_dev is mainly used by the machine driver to specify analog devices,
which are registered as codecs. Making it more like a generic component
can help the machine driver to use it to specify any component with
topology info by name.

Details:
- Remove the stub 'rtd_aux' array from the soc card.
- Add a list 'aux_comp_list' to store the components of aux_devs.
  And add a list head 'list_aux' to struct snd_soc_component, for adding
  such components to the above list.
- Add a 'init' ops to a component for machine specific init.
  soc_bind_aux_dev() will set it to be aux_dev's init. And it will be
  called when probing the component.
- soc_bind_aux_dev() will also search components by name of an aux_dev,
  since it may not be a codec.
- Move probing of aux_devs before checking new DAI links brought by
  topology.
- Move removal of aux_devs later than removal of links. Because topology
  of aux components may register DAIs and the DAI drivers will go with
  removal of the aux components, we want soc_remove_link_dais() to remove
  the DAIs at first.

Charles Keepax 783513eec3 ASoC: Use nested lock for snd_soc_dapm_mutex_lock
snd_soc_dapm_mutex_lock currently uses the un-nested call which can
cause lockdep warnings when called from control handlers (a relatively
common usage) and using modules. As creating the control causes a
potential mutex inversion with the handler, creating the control will
take the controls_rwsem under the dapm_mutex and accessing the control
will take the dapm_mutex under controls_rwsem.

All the users look like they want to be using the runtime class of the
lock anyway, so this patch just changes snd_soc_dapm_mutex_lock to use
the nested call, with the SND_SOC_DAPM_CLASS_RUNTIME class.

This patch does it, adds two new helper functions for setting N/CTS

A machine driver can register the two ops.

When a DAI link is added or removed by a component's topology, the
ASoC core can call the ops to notify the machine driver for extra
intialization or destruction.

E.g. topology can create FE DAI links from a cpu DAI component, and
the machine driver may define an add_dai_link ops to set machine-specific
.init ops for the DAI link.

Mengdong Lin 1a497983a5 ASoC: Change the PCM runtime array to a list
Currently the number of DAI links is statically defined by the machine
driver at build time using an array. This makes it difficult to shrink/
grow the number of DAI links at runtime in order to reflect any changes
in topology.

We can change the DAI link array in the core to a list so that PCMs and
FE DAI links can be added and deleted at runtime to reflect changes in
use case and DSP topology. The machine driver can still register DAI links
as an array.

As the 1st step, this patch change the PCM runtime array to a list. A new
PCM runtime is added to the list when a DAI link is bound successfully.

Later patches will further implement the DAI link list.

More:
- define snd_soc_new/free_pcm_runtime() to create/free a runtime.
- define soc_add_pcm_runtime() to add a runtime to the rtd list.
- define soc_remove_pcm_runtimes() to clean up the runtime list.

- traverse the rtd list to probe the link components and dais.

- Add a field "num" to PCM runtime struct, used to specify the device
  number when creating the pcm device, and for a soc card to access
  its dai_props array.

- The following 3rd party machine/platform drivers iterate the rtd list
  to check the runtimes:
  sound/soc/intel/atom/sst-mfld-platform-pcm.c
  sound/soc/intel/boards/cht_bsw_rt5645.c
  sound/soc/intel/boards/cht_bsw_rt5672.c

Currently there is no clear definition of what FSYNC polarity is.
Different drivers use its own definition of what is "normal" and what is
"inverted" fsync. This leads to compatibility problems between drivers.

For example TegraX1 driver assumes that DSP-A format with frames
starting at rising FSYNC edge has "inverted" polarity,
while RT5677 assumes it is "normal" polarity.

Explicitly specify meaning of BCLK/FSYNC polarity to avoid future
compatibility problems.

Lars-Peter Clausen bc1043cdcd ALSA: Add helper function to add single value constraint
The recommended and most efficient way to constraint a configuration
parameter to a single value is to set the minimum and maximum allowed
values to the same value, i.e. calling snd_pcm_hw_constraint_minmax() with
the same value for min and max.

It is not necessarily obvious though that this is the approach that should
be taken and some drivers have come up with other ways of solving this
problem, e.g. installing a list constraint with a single item. List
constraints are dynamic constraints though and hence less efficient than
the static min-max constraint.

This patch introduces a new helper function called
snd_pcm_hw_constraint_single() which only takes a single value has the same
effect as calling snd_pcm_hw_constraint_minmax() with the same values for
min and max. But it is hopefully semantically more expressive, making it
clear that this is the preferred way of setting a single value constraint.

For distinguishing the difference between HDA legacy and ext codec
driver entries, we need to expose the value corresponding to type
field.  This patch adds a new field, api_version, to hda_device_id
struct, so that this information is embedded in modalias string.

Although the information is basically redundant (struct hdac_device
already has type field), the helper that extracts from
MODULE_DEVICE_TABLE() won't take it account except for the exported
table entries themselves.  So we need to put the same information in
the table, too.

Charles Keepax 34198710f5 ASoC: Add info callback for SX_TLV controls
SX_TLV controls are intended for situations where the register behind
the control has some non-zero value indicating the minimum gain
and then gains increasing from there and eventually overflowing through
zero.

Currently every CODEC implementing these controls specifies the minimum
as the non-zero value for the minimum and the maximum as the number of
gain settings available.

This means when the info callback subtracts the minimum value from the
maximum value to calculate the number of gain levels available it is
actually under reporting the available levels. This patch fixes this
issue by adding a new snd_soc_info_volsw_sx callback that does not
subtract the minimum value.

This structure was added by 4d96eb255c ('ALSA: pcm_lib - add possibility

information of latest 10 pointer movements (=XRUN_LOG_CNT). When
CONFIG_SND_PCM_XRUN_DEBUG is configured, 'struct snd_pcm_runtime' has
'hwptr_log' member with a pointer to the structure. When calling
xrun_log() in pcm_lib.c, the structure was allocated to the pointer.
When calling snd_pcm_detach_substream() in pcm.c, the allocated pointer
is released.

In f5914908a5 ('ALSA: pcm: Replace PCM hwptr tracking with tracepoints'),
the pointer logging is replaced with using Linux Kernel Tracepoints. The
structure was also removed, while it's just declared. The member and kfree
still remains.

This commit removes the member and related codes. I think this was
overlooked because it brings no errors/warnings to C compilers.

Mengdong Lin 88a17d8fb7 ASoC: topology: Bind vendor specific kcontrol handlers before standard ones
Vendor specific handlers should override standard handlers. So we can
handle things in the order from specific to generic.

Jeeja KP ee8bc4df1b ALSA: hdac: Add support to enable SPIB for hdac ext stream
The drivers need to set the spib and maxfifios values, so add
these new APIs snd_hdac_ext_stream_set_spib() and
snd_hdac_ext_stream_set_spbmaxfifo() APIs

For these APIs we also need to have spib and fifos pointer, so
add these to hdac_ext_stream and initialize them at stream init

Jeeja KP c5b0c09b8f ALSA: hdac: Add snd_hdac_ext_bus_link_power_down_all()
New HDA controllers like Skylake sport multiple HDA links, so we need a
helper to turn off all the links in one go while suspending the device so
add snd_hdac_ext_bus_link_power_down_all() API

Vinod Koul 18dfd79d92 ALSA: hdac: add snd_hdac_refresh_widget_sysfs()
Some codecs like Intel HDMI by default do not show up all the pins, they
have to be manually enabled, so we need to refresh the codec widgets and
then recreate the sysfs tree. So add new API snd_hdac_refresh_widget_sysfs()
to do this. It should be be used by codec driver after sending magic verbs
to codec

Mark Brown 78b50f3914 ASoC: topology: Add Kconfig option for topology
Allow the topology code to be compiled out so that users who don't need
topology don't need to havve the code compiled in, saving them some
memory.

Some more configuration could be added to remove some of the hooks into
the core data structures but that is probably best done with some
refactoring to use functions to do the updates of the data structures
rather than ifdefing in the code as we'd need to do at the minute.
