Kuninori Morimoto ef641e5d5e ASoC: add Component level set_pll
In current ALSA SoC, Codec only has set_pll feature.
Codec will be merged into Component in next generation ALSA SoC,
thus current Codec specific feature need to be merged into it.
This is glue patch for it.

Takashi Iwai 7d8e829201 ALSA: Get rid of card power_lock
Currently we're taking power_lock at each card component for assuring
the power-up sequence, but it doesn't help anything in the
implementation at the moment: it just serializes unnecessarily the
callers, but it doesn't protect about the power state change itself.
It used to have some usefulness in the early days where we managed the
PM manually.  But now the suspend/resume core procedure is beyond our
hands, and power_lock lost its meaning.

This patch drops the power_lock from allover the places.
There shouldn't be any issues by this change, as it's no helper
regarding the power state change.  Rather we'll get better performance
by removing the serialization; which is the only slight concern of any
behavior change, but it can't be a showstopper, after all.

Kuninori Morimoto a0ac441152 ASoC: soc-core: add snd_soc_rtdcom_xxx()
Current snd_soc_pcm_runtime has platform / codec pointers, and we could
use these specific pointer. But these will be replaced to more generic
"component" soon, and will need more generic method to get each
connected component pointer from rtd.

This patch adds new snd_soc_rtdcom_xxx() to connect/disconnect
component to rtd. It means same as previous "platform" / "codec"
pointer style, but more generic.
We can find necessary component pointer from rtd by using component
driver name on snd_soc_rtdcom_lookup().

Here, the reason why it uses "driver name" is that "component name"
was created by fmt_single_name() and difficult to use it from driver.
Driver of course knows its "driver name", thus, using it is more easy.

Johan Hovold c641e5b207 ASoC: fix pcm-creation regression
This reverts commit 99b04f4c40 ("ASoC: add Component level
pcm_new/pcm_free"), which started calling the pcm_new callback for every
component in a *card* when creating a new pcm, something which does not
seem to make any sense.

This specifically led to memory leaks in systems with more than one
platform component and where DMA memory is allocated in the
platform-driver callback. For example, when both mcasp devices are being
used on an am335x board, DMA memory would be allocated twice for every
DAI link during probe.

When CONFIG_SND_VERBOSE_PROCFS was set this fortunately also led to
warnings such as:

WARNING: CPU: 0 PID: 565 at ../fs/proc/generic.c:346 proc_register+0x110/0x154
proc_dir_entry 'sub0/prealloc' already registered

Since there seems to be no users of the new component callbacks, and the
current implementation introduced a regression, let's revert the
offending commit for now.

Takashi Iwai 4b671f5774 ALSA: pcm: Add an ioctl to specify the supported protocol version
We have an ioctl to inform the PCM protocol version the running kernel
supports, but there is no way to know which protocol version the
user-space can understand.  This lack of information caused headaches
in the past when we tried to extend the ABI.  For example, because we
couldn't guarantee the validity of the reserved bytes, we had to
introduce a new ioctl SNDRV_PCM_IOCTL_STATUS_EXT for assigning a few
new fields in the formerly reserved bits.  If we could know that it's
a new alsa-lib, we could assume the availability of the new fields,
thus we could have reused the existing SNDRV_PCM_IOCTL_STATUS.

In order to improve the ABI extensibility, this patch adds a new ioctl
for user-space to inform its supporting protocol version to the
kernel.  By reporting the supported protocol from user-space, the
kernel can judge which feature should be provided and which not.

With the addition of the new ioctl, the PCM protocol version is bumped
to 2.0.14, too.  User-space checks the kernel protocol version via
SNDRV_PCM_INFO_PVERSION, then it sets the supported version back via
SNDRV_PCM_INFO_USER_PVERSION.

Usually common set of operations are used for it.

SNDRV_PCM_IOCTL1_INFO is one of the requests. According to code comment,
it has been obsoleted in the old days.

We can see old releases in ftp.alsa-project.org. The command was firstly
introduced in v0.5.0 release as SND_PCM_IOCTL1_INFO, to allow drivers to
fill data of 'struct snd_pcm_channel_info' type. In v0.9.0 release,
this was obsoleted by the other commands for ioctl(2) such as
SNDRV_PCM_IOCTL_CHANNEL_INFO.

This commit removes the long-abandoned command, bye.

Takashi Iwai 3d774d5ef0 ALSA: seq: Allow the tristate build of OSS emulation
Currently OSS sequencer emulation is tied with ALSA sequencer core,
both are built in the same level; i.e. when CONFIG_SND_SEQUENCER=y,
the OSS sequencer emulation is also always built-in, even though the
functionality can be built as an individual module.

This patch changes the rule and allows users to build snd-seq-oss
module while others are built-in.  Essentially, it's just a few simple
changes in Kconfig and Makefile.  Some driver codes like opl3 need to
convert from the simple ifdef to IS_ENABLED().  But that's all.

You might wonder how about the dependency: right, it can be messy, but
it still works.  Since we rewrote the sequencer binding with the
standard bus, the driver can be bound at any time on demand.  So, the
synthesizer driver module can be loaded individually from the OSS
emulation core before/after it.

Takashi Iwai 6854121372 ALSA: pcm: Direct in-kernel read/write support
Now all materials are ready, let's allow the direct in-kernel
read/write, i.e. a kernel-space buffer is passed for read or write,
instead of the normal user-space buffer.  This feature is used by OSS
layer and UAC1 driver, for example.

The __snd_pcm_lib_xfer() takes in_kernel argument that indicates the
in-kernel buffer copy.  When this flag is set, another transfer code
is used.  It's either via copy_kernel PCM ops or the normal memcpy(),
depending on the driver setup.

As external API, snd_pcm_kernel_read(), *_write() and other variants
are provided.

That's all.  This support is really simple because of the code
refactoring until now.

Takashi Iwai 29d1a873de ALSA: pcm: Introduce copy_user, copy_kernel and fill_silence ops
For supporting the explicit in-kernel copy of PCM buffer data, and
also for further code refactoring, three new PCM ops, copy_user,
copy_kernel and fill_silence, are introduced.  The old copy and
silence ops will be deprecated and removed later once when all callers
are converted.

The copy_kernel ops is the new one, and it's supposed to transfer the
PCM data from the given kernel buffer to the hardware ring-buffer (or
vice-versa depending on the stream direction), while the copy_user ops
is equivalent with the former copy ops, to transfer the data from the
user-space buffer.

The major difference of the new copy_* and fill_silence ops from the
previous ops is that the new ops take bytes instead of frames for size
and position arguments.  It has two merits: first, it allows the
callback implementation often simpler (just call directly memcpy() &
co), and second, it may unify the implementations of both interleaved
and non-interleaved cases, as we'll see in the later patch.

As of this stage, copy_kernel ops isn't referred yet, but only
copy_user is used.

This reverts commit c6644119a3 and
restores the ability to specify DMA channel names per DAI dma_data.
Unfortunately the functionality removed in the patch being reverted
cannot be entirely replaced by specifying DMA channel names in struct
snd_dmaengine_pcm_config as that does not cover devices with more than
2 DMA channels.

Together with patch "ASoC: Revert "samsung: Remove unneeded

Liam Girdwood 345233d7c6 ASoC: core: Add API to use DMI name in sound card long name
Intel DSP platform drivers are used by many different devices but are
difficult for userspace to differentiate. This patch adds an API to allow
the DMI name to be used in the sound card long name, thereby helping
userspace load the correct UCM configuration. Usually machine drivers
uses their own name as the sound card name (short name), and leave the
long name and driver name blank. This API will use the DMI info like
vendor, product and board to make up the card long name. If the machine
driver has already explicitly set the long name, this API will do nothing.

This patch also allows for further differentiation as many devices that
share the same DMI name i.e. Minnowboards, UP boards may be configured
with different codecs or firmwares. The API supports flavoring the DMI
name into the card longname to provide the extra differentiation required
for these devices.

For Use Case Manager (UCM) in the user space, changing card long name by
this API is backward compatible, since the card name does not change. For
a given sound card, even if there is no device-specific UCM configuration
file that uses the card long name, UCM will fall back to load the default
configuration file that uses the card name.

Sylwester Nawrocki d2e3a1358c ASoC: Fix binding and probing of auxiliary components
Currently binding of auxiliary devices doesn't work as in
soc_bind_aux_dev() function a bound component is not being added
to any list and in soc_probe_aux_devices() we are trying to walk
the component_dev_list list to probe auxiliary components but
at that time this list doesn't contain any auxiliary components
since they are being added to the card only in soc_probe_component().

This patch adds a list to the card where are stored bound but not
probed auxiliary devices, so that all aux devices can be probed.

Takashi Sakamoto 9e4d59ada4 ASoC: hdmi-codec: use unsigned type to structure members with bit-field
This is a fix for Linux 4.10-rc1.

In C language specification, a bit-field is interpreted as a signed or
unsigned integer type consisting of the specified number of bits.

In GCC manual, the range of a signed bit field of N bits is from
-(2^N) / 2 to ((2^N) / 2) - 1
https://www.gnu.org/software/gnu-c-manual/gnu-c-manual.html#Bit-Fields

Therefore, when defined as 1 bit-field with signed type, variables can
represents -1 and 0.

The snd-soc-hdmi-codec module includes a structure which has signed type
members with bit-fields. Codes of this module assign 0 and 1 to the
members. This seems to result in implementation-dependent behaviours.

As of v4.10-rc1 merge window, outside of sound subsystem, this structure
is referred by below GPU modules.
 - tda998x
 - sti-drm
 - mediatek-drm-hdmi
 - msm

As long as I review their codes relevant to the structure, the structure
members are used just for condition statements and printk formats.
My proposal of change is a bit intrusive to the printk formats but this
may be acceptable.

Totally, it's reasonable to use unsigned type for the structure members.
This bug is detected by Sparse, static code analyzer with below warnings.

./include/sound/hdmi-codec.h:39:26: error: dubious one-bit signed bitfield
./include/sound/hdmi-codec.h:40:28: error: dubious one-bit signed bitfield

Linus Torvalds ce38207f16 sound updates for 4.10-rc1
No dramatic changes are found in this development cycle, but as usual,
 many commits are applied in a wide range of drivers.
 
 Most of big changes are in ASoC, where a few bits of framework work
 and quite a lot of cleanups and improvements to existing code have
 been done.  The rest are usual stuff, a few HD-audio and USB-audio
 quirks and fixes, as well as the drop of kthread usages in the whole
 subsystem.
 
 Below are some highlights:
 
 ASoC:
 - Support for stereo DAPM controls
 - Some initial work on the of-graph sound card
 - regmap conversions of the remaining AC'97 drivers
 - A new version of the topology ABI; this should be backward compatible
 - Updates / cleanups of rsnd, sunxi, sti, nau8825, samsung, arizona,
   Intel skylake, atom-sst
 - New drivers for Cirrus Logic CS42L42, Qualcomm MSM8916-WCD, and
   Realtek RT5665
 
 USB-audio:
 - Yet another race fix at disconnection
 - Tolerated packet size calculation for some Android devices
 - Quirks for Axe-Fx II, QuickCam, TEAC 501/503
 
 HD-audio:
 - Improvement of Dell pin fixup mapping
 - Quirks for HP Z1 Gen3, Alienware 15 R2 2016 and ALC622 headset mic

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 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
commit might certainly brings no confusions to user land.

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

Srinivas Kandagatla dcc0799bf7 ASoC: Introduce SOC_SINGLE_S8_TLV() macro
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.
