fa7d16734f ALSA: compress: document 'chan_map' member in snd_dec_opus
When building kernel docs, the following warning appeared:

  WARNING: ./include/uapi/sound/compress_params.h:364
  struct member 'chan_map' not described in 'snd_dec_opus'

The inline struct 'snd_dec_opus_ch_map' inside 'snd_dec_opus' was not
properly documented. This patch documents the 'chan_map' member and its
fields (stream_count, coupled_count, channel_map), resolving the warning.

b8d8265a0d ASoC: Updates for v6.18
A relatively quiet release for ASoC, we've had a lot of maintainance
 work going on and several new drivers but really the most remarkable
 thing is that we removed a driver, the WL1273 driver used in some old
 Nokia systems that have had the underlying system support removed from
 the kernel.
 
  - Morimoto-san continues his work on cleanups of the core APIs and
    enforcement of abstraction layers.
  - Lots of cleanups and conversions of DT bindings.
  - Substantial maintainance work on the Intel AVS drivers.
  - Support for Qualcomm Glymur and PM4125, Realtek RT1321, Shanghai
    FourSemi FS2104/5S, Texas Instruments PCM1754.
  - Remove support for TI WL1273.

86eec88c5b ALSA: compress_offload: Add SNDRV_COMPRESS_AVAIL64 ioctl
The previous patch introduced a 64-bit timestamp ioctl
(SNDRV_COMPRESS_TSTAMP64). To provide a consistent API, this patch
adds a corresponding 64-bit version of the SNDRV_COMPRESS_AVAIL ioctl.

A new struct snd_compr_avail64 is added to the UAPI, which includes
the 64-bit timestamp. The existing ioctl implementation is refactored
to handle both the 32-bit and 64-bit variants.

f20a53974f ALSA: compress_offload: Add SNDRV_COMPRESS_TSTAMP64 ioctl
The previous patch introduced the internal infrastructure for handling
64-bit timestamps. This patch exposes this capability to user-space.

Define the new ioctl command SNDRV_COMPRESS_TSTAMP64, which allows
applications to fetch the overflow-safe struct snd_compr_tstamp64.

The ioctl dispatch table is updated to handle the new command by
calling a new snd_compr_tstamp64 handler, while the legacy path is
renamed to snd_compr_tstamp32 for clarity.

This patch bumps the SNDRV_COMPRESS_VERSION to 0.4.0.

2c92e2fbe9 ALSA: compress_offload: Add 64-bit safe timestamp infrastructure
The copied_total field in struct snd_compr_tstamp is a 32-bit
value that can overflow on long-running high-bitrate streams,
leading to incorrect calculations for buffer availablility.

This patch adds a 64-bit safe timestamping mechanism.
A new UAPI struct, snd_compr_tstamp64, is added which uses 64-bit
types for byte counters. The relevant ops structures across the
ASoC and core compress code are updated to use this new struct.
ASoC drivers are updated to use u64 counters.

Internal timestamps being u64 now, a compatibility function is added
to convert the 64-bit timestamp back to the 32-bit format for legacy
ioctl callers.

ASoC: qcom: audioreach: add support for static calibration
This change adds support for static calibration data via ASoC topology
file. This static calibration data could include binary blob of data
that is required by specific module and is not part of topology tokens.

Reason for adding this support is to allow loading module specific data
that can not be part of the tplg tokens, example, Echo and Noise cancelling
module needs a blob of calibration data to function correctly.

This support is also one of the building block for adding speaker
protection support.

Tested this with Single Mic ECNS(Echo and Noise Cancellation).

tplg can now contain this calibration data like:

SectionWidget."stream2.SMECNS_V224" {
	...
	data [
		...
		"stream2.SMECNS_V224_cfg_data"
	]
}

SectionData."stream2.SMECNS_V224_cfg_data" {
	words "0x00000330, 0x01001006,0x00000000,0x00000000,

46757a3e7d ALSA: FCP: Add Focusrite Control Protocol driver
Add a new kernel driver for the Focusrite Control Protocol (FCP),
which is used by Focusrite Scarlett 2nd Gen, 3rd Gen, 4th Gen, Clarett
USB, Clarett+, and Vocaster series audio interfaces. This driver
provides a user-space control interface via ALSA's hwdep subsystem.

Unlike the existing Scarlett2 driver which implements all ALSA
controls in kernel space, this new FCP driver takes a different
approach by providing a minimal kernel interface that allows a
user-space driver to send FCP commands and receive notifications. The
only control implemented in kernel space is the Level Meter, since it
requires frequent polling of volatile data.

While this driver supports all interfaces that the Scarlett2 driver
works with, it is initially enabled only for 4th Gen 16i16, 18i16,
and 18i20 interfaces that are not supported by the Scarlett2 driver.

In the original change, rawmidi_info.tied_device showed -1 for the

check the protocol version and judge the value conditionally, which
is rather error-prone.

Instead, set the tied_device = 0 to be default as unknown, and
indicate the real device with the offset 1, for achieving more
backward compatibility.

3ab4a3199c ALSA: seq: Notify UMP EP and FB changes
So far we notify the sequencer client and port changes upon UMP FB
changes, but those aren't really corresponding to the UMP updates.
e.g. when a FB info gets updated, it's not notified but done only when
some of sequencer port attribute is changed.  This is no ideal
behavior.

This patch adds the two new sequencer event types for notifying the
UMP EP and FB changes via the announce port.  The new event takes
snd_seq_ev_ump_notify type data, which is compatible with
snd_seq_addr (where the port number is replaced with the block
number).

The events are sent when the EP and FB info gets updated explicitly
via ioctl, or the backend UMP receives the corresponding UMP
messages.

The sequencer protocol version is bumped to 1.0.5 along with it.

ASoC: fsl: add memory to memory function for ASRC
Merge series from Shengjiu Wang <shengjiu.wang@nxp.com>:

This function is base on the accelerator implementation
for compress API:
04177158cf98 ("ALSA: compress_offload: introduce accel operation mode")

Audio signal processing also has the requirement for memory to
memory similar as Video.

This asrc memory to memory (memory ->asrc->memory) case is a non
real time use case.

User fills the input buffer to the asrc module, after conversion, then asrc
sends back the output buffer to user. So it is not a traditional ALSA playback
and capture case.

Because we had implemented the "memory -> asrc ->i2s device-> codec"
use case in ALSA.  Now the "memory->asrc->memory" needs
to reuse the code in asrc driver, so the patch 1 and patch 2 is for refining
the code to make it can be shared by the "memory->asrc->memory"
driver.

Other change is to add memory to memory support for two kinds of i.MX ASRC
modules.

sample rates. And add 'src_d' in union snd_codec_options
structure. These are mainly used for capbility query.

04177158cf ALSA: compress_offload: introduce accel operation mode
There is a requirement to expose the audio hardware that accelerates various
tasks for user space such as sample rate converters, compressed
stream decoders, etc.

This is description for the API extension for the compress ALSA API which
is able to handle "tasks" that are not bound to real-time operations
and allows for the serialization of operations.

For details, refer to "compress-accel.rst" document.

ASoC: SOF: ipc: replace "enum sof_comp_type" field with "uint32_t"
Normally, the type of enums is "unsigned int" or "int". GCC has
the "-fshort-enums" option, which instructs the compiler to
use the smallest data type that can hold all the values in
the enum (i.e: char, short, int or their unsigned variants).

According to the GCC documentation, "-fshort-enums" may be
default on some targets. This seems to be the case for SOF
when built for a certain 32-bit ARM platform.

On Linux, this is not the case (tested with "aarch64-linux-gnu-gcc")
which means enums such as "enum sof_comp_type" will end up having
different sizes on Linux and SOF. Since "enum sof_comp_type" is used in
IPC-related structures such as "struct sof_ipc_comp", this means
the fields of the structures will end up being placed at different
offsets. This, in turn, leads to SOF not being able to properly
interpret data passed from Linux.

With this in mind, replace "enum sof_comp_type" from
"struct sof_ipc_comp" with "uint32_t".

37745918e0 ALSA: timer: Introduce virtual userspace-driven timers
Implement two ioctl calls in order to support virtual userspace-driven
ALSA timers.

The first ioctl is SNDRV_TIMER_IOCTL_CREATE, which gets the
snd_timer_uinfo struct as a parameter and puts a file descriptor of a
virtual timer into the `fd` field of the snd_timer_unfo structure. It
also updates the `id` field of the snd_timer_uinfo struct, which
provides a unique identifier for the timer (basically, the subdevice
number which can be used when creating timer instances).

This patch also introduces a tiny id allocator for the userspace-driven
timers, which guarantees that we don't have more than 128 of them in the
system.

Another ioctl is SNDRV_TIMER_IOCTL_TRIGGER, which allows us to trigger
the virtual timer (and calls snd_timer_interrupt for the timer under
the hood), causing all of the timer instances binded to this timer to
execute their callbacks.

The maximum amount of ticks available for the timer is 1 for the sake of
simplicity of the userspace API. 'start', 'stop', 'open' and 'close'
callbacks for the userspace-driven timers are empty since we don't
really do any hardware initialization here.

0079c9d1e5 ALSA: ump: Handle MIDI 1.0 Function Block in MIDI 2.0 protocol
The UMP v1.1 spec says in the section 6.2.1:
"If a UMP Endpoint declares MIDI 2.0 Protocol but a Function Block
represents a MIDI 1.0 connection, then may optionally be used for
messages to/from that Function Block."

It implies that the driver can (and should) keep MIDI 1.0 CVM
exceptionally for those FBs even if UMP Endpoint is running in MIDI
2.0 protocol, and the current driver lacks of it.

This patch extends the sequencer port info to indicate a MIDI 1.0
port, and tries to send/receive MIDI 1.0 CVM as is when this port is
the source or sink.  The sequencer port flag is set by the driver at
parsing FBs and GTBs although application can set it to its own
user-space clients, too.

fefbbdfb59 ALSA: seq: Add tempo base unit for MIDI2 Set Tempo messages
MIDI2 Set Tempo message defines the tempo in 10ns unit for finer
accuracy, while MIDI1 was defined in 1us unit.  For adapting this
different unit, introduce "tempo_base" field to snd_seq_queue_tempo
struct so that user-space can pass the proper tempo base unit.

The accepted value is limited, it must be either 0, 10 or 1000.

The protocol version is bumped to 1.0.4 along with this.

The access with the older protocol version ignores the tempo-base
value in ioctls and always treats as 1000.

f05c1ffc27 ALSA: pcm: reinvent the stream synchronization ID API
Until the commit e11f0f90a626 ("ALSA: pcm: remove SNDRV_PCM_IOCTL1_INFO
internal command"), there was a possibility to pass information
about the synchronized streams to the user space. The mentioned
commit removed blindly the appropriate code with an irrelevant comment.

The revert may be appropriate, but since this API was lost for several
years without any complains, it's time to improve it. The hardware
parameters may change the used stream clock source (e.g. USB hardware)
so move this synchronization ID to hw_params as read-only field.

It seems that pipewire can benefit from this API (disable adaptive
resampling for perfectly synchronized PCM streams) now.

Note that the contents of ID is not supposed to be used for direct
comparison with a specific byte sequence. The "empty" case is when
all bytes are zero (driver does not offer this information)
and all other cases must be only used for equal comparison among
PCM streams (including different sound cards) if they are using
identical hardware clock.

85df6b5a66 ALSA: pcm: clarify and fix default msbits value for all formats
Return used most significant bits from sample bit-width rather than the whole
physical sample word size. The starting bit offset is defined in the format
itself.

The behaviour is not changed for 32-bit formats like S32_LE. But with this
change - msbits value 24 instead 32 is returned for 24-bit formats like S24_LE
etc.

Also, commit 2112aa034907 ("ALSA: pcm: Introduce MSBITS subformat interface")
compares sample bit-width not physical sample bit-width to reset MSBITS_MAX bit
from the subformat bitmask.

Probably no applications are using msbits value for other than S32_LE/U32_LE
formats, because no drivers are reducing msbits value for other formats (with
the msb offset) at the moment.

For sanity, increase PCM protocol version, letting the user space to detect
the changed behaviour.

ASoC: SOF: Wire up buffer flags
Buffer flags have been in firmware for ages but were never fully
implemented in the topology/kernel system. This commit finishes off the
implementation.

2112aa0349 ALSA: pcm: Introduce MSBITS subformat interface
Improve granularity of format selection for S32/U32 formats by adding
constants representing 20, 24 and MAX most significant bits.

The MAX means the maximum number of significant bits which can
the physical format hold. For 32-bit formats, MAX is related
to 32 bits. For 8-bit formats, MAX is related to 8 bits etc.

As there is only one user currently (format S32_LE), subformat is
represented by a simple u32 and stores flags only for that one user
alone. The approach of subformat being part of struct snd_pcm_hardware
is a compromise between ALSA and ASoC allowing for
hw_params-intersection code to be alloc/free-less while not adding any
new responsibilities to ASoC runtime structures.
