Merge tag 'sound-6.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai: "Lots of changes as usual, but the only significant stuff in ALSA core part is the MIDI 2.0 support, while ASoC core kept receiving the code refactoring. The majority of changes are seen rather in device drivers, and quite a few new drivers can be found there. Here we go, some highlights: ALSA and ASoC Core: - Support of MIDI 2.0 devices: rawmidi and sequencer API have been extended for the support of the new UMP (Universal MIDI Packet) protocol, USB audio driver got the USB MIDI 2.0 interface support - Continued refactoring around ASoC DAI links and the ordering of trigger callbacks - PCM ABI extension for better drain support ASoC Drivers: - Conversions of many drivers to use maple tree based caches - Everlasting improvement works on ASoC Intel drivers - Compressed audio support for Qualcomm - Support for AMD SoundWire, Analog Devices SSM3515, Google Chameleon, Ingenic X1000, Intel systems with various CODECs, Loongson platforms, Maxim MAX98388, Mediatek MT8188, Nuvoton NAU8825C, NXP platforms with NAU8822, Qualcomm WSA884x, StarFive JH7110, Texas Instruments TAS2781 HD-audio: - Quirks for HP and ASUS machines - CS35L41 HD-audio codec fixes - Loongson HD-audio support Misc: - A new virtual PCM test driver for kselftests - Continued refactoring and improvements on the legacy emu10k1 driver" * tag 'sound-6.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (556 commits) ALSA: hda/realtek: Enable mute/micmute LEDs and limit mic boost on EliteBook ASoC: hdmi-codec: fix channel info for compressed formats ALSA: pcm: fix ELD constraints for (E)AC3, DTS(-HD) and MLP formats ASoC: core: Always store of_node when getting DAI link component ASoC: tas2781: Fix error code in tas2781_load_calibration() ASoC: amd: update pm_runtime enable sequence ALSA: ump: Export MIDI1 / UMP conversion helpers ASoC: tas2781: fix Kconfig dependencies ASoC: amd: acp: remove acp poweroff function ASoC: amd: acp: clear pdm dma interrupt mask ASoC: codecs: max98090: Allow dsp_a mode ASoC: qcom: common: add default jack dapm pins ASoC: loongson: fix address space confusion ASoC: dt-bindings: microchip,sama7g5-pdmc: Simplify "microchip,mic-pos" constraints ASoC: tegra: Remove stale comments in AHUB ASoC: tegra: Use normal system sleep for ASRC ALSA: hda/realtek: Add quirks for ROG ALLY CS35l41 audio ASoC: fsl-asoc-card: Allow passing the number of slots in use ASoC: codecs: wsa884x: Add WSA884x family of speakers ASoC: dt-bindings: qcom,wsa8840: Add WSA884x family of speakers ...

+The Virtual PCM Test Driver
+===========================
+
+The Virtual PCM Test Driver emulates a generic PCM device, and can be used for
+testing/fuzzing of the userspace ALSA applications, as well as for testing/fuzzing of
+the PCM middle layer. Additionally, it can be used for simulating hard to reproduce
+problems with PCM devices.
+
+What can this driver do?
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+At this moment the driver can do the following things:
+ * Simulate both capture and playback processes
+ * Generate random or pattern-based capturing data
+ * Inject delays into the playback and capturing processes
+ * Inject errors during the PCM callbacks
+
+It supports up to 8 substreams and 4 channels. Also it supports both interleaved and
+non-interleaved access modes.
+
+Also, this driver can check the playback stream for containing the predefined pattern,
+which is used in the corresponding selftest (alsa/pcmtest-test.sh) to check the PCM middle
+layer data transferring functionality. Additionally, this driver redefines the default
+RESET ioctl, and the selftest covers this PCM API functionality as well.
+
+Configuration
+-------------
+
+The driver has several parameters besides the common ALSA module parameters:
+
+ * fill_mode (bool) - Buffer fill mode (see below)
+ * inject_delay (int)
+ * inject_hwpars_err (bool)
+ * inject_prepare_err (bool)
+ * inject_trigger_err (bool)
+
+
+Capture Data Generation
+-----------------------
+
+The driver has two modes of data generation: the first (0 in the fill_mode parameter)
+means random data generation, the second (1 in the fill_mode) - pattern-based
+data generation. Let's look at the second mode.
+
+First of all, you may want to specify the pattern for data generation. You can do it
+by writing the pattern to the debugfs file. There are pattern buffer debugfs entries
+for each channel, as well as entries which contain the pattern buffer length.
+
+ * /sys/kernel/debug/pcmtest/fill_pattern[0-3]
+ * /sys/kernel/debug/pcmtest/fill_pattern[0-3]_len
+
+To set the pattern for the channel 0 you can execute the following command:
+
+.. code-block:: bash
+
+ echo -n mycoolpattern > /sys/kernel/debug/pcmtest/fill_pattern0
+
+Then, after every capture action performed on the 'pcmtest' device the buffer for the
+channel 0 will contain 'mycoolpatternmycoolpatternmycoolpatternmy...'.
+
+The pattern itself can be up to 4096 bytes long.
+
+Delay injection
+---------------
+
+The driver has 'inject_delay' parameter, which has very self-descriptive name and
+can be used for time delay/speedup simulations. The parameter has integer type, and
+it means the delay added between module's internal timer ticks.
+
+If the 'inject_delay' value is positive, the buffer will be filled slower, if it is
+negative - faster. You can try it yourself by starting a recording in any
+audiorecording application (like Audacity) and selecting the 'pcmtest' device as a
+source.
+
+This parameter can be also used for generating a huge amount of sound data in a very
+short period of time (with the negative 'inject_delay' value).
+
+Errors injection
+----------------
+
+This module can be used for injecting errors into the PCM communication process. This
+action can help you to figure out how the userspace ALSA program behaves under unusual
+circumstances.
+
+For example, you can make all 'hw_params' PCM callback calls return EBUSY error by
+writing '1' to the 'inject_hwpars_err' module parameter:
+
+.. code-block:: bash
+
+ echo 1 > /sys/module/snd_pcmtest/parameters/inject_hwpars_err
+
+Errors can be injected into the following PCM callbacks:
+
+ * hw_params (EBUSY)
+ * prepare (EINVAL)
+ * trigger (EINVAL)
+
+Playback test
+-------------
+
+This driver can be also used for the playback functionality testing - every time you
+write the playback data to the 'pcmtest' PCM device and close it, the driver checks the
+buffer for containing the looped pattern (which is specified in the fill_pattern
+debugfs file for each channel). If the playback buffer content represents the looped
+pattern, 'pc_test' debugfs entry is set into '1'. Otherwise, the driver sets it to '0'.
+
+ioctl redefinition test
+-----------------------
+
+The driver redefines the 'reset' ioctl, which is default for all PCM devices. To test
+this functionality, we can trigger the reset ioctl and check the 'ioctl_test' debugfs
+entry:
+
+.. code-block:: bash
+
+ cat /sys/kernel/debug/pcmtest/ioctl_test
+
+If the ioctl is triggered successfully, this file will contain '1', and '0' otherwise.

+=================
+MIDI 2.0 on Linux
+=================
+
+General
+=======
+
+MIDI 2.0 is an extended protocol for providing higher resolutions and
+more fine controls over the legacy MIDI 1.0. The fundamental changes
+introduced for supporting MIDI 2.0 are:
+
+- Support of Universal MIDI Packet (UMP)
+- Support of MIDI 2.0 protocol messages
+- Transparent conversions between UMP and legacy MIDI 1.0 byte stream
+- MIDI-CI for property and profile configurations
+
+UMP is a new container format to hold all MIDI protocol 1.0 and MIDI
+2.0 protocol messages. Unlike the former byte stream, it's 32bit
+aligned, and each message can be put in a single packet. UMP can send
+the events up to 16 "UMP Groups", where each UMP Group contain up to
+16 MIDI channels.
+
+MIDI 2.0 protocol is an extended protocol to achieve the higher
+resolution and more controls over the old MIDI 1.0 protocol.
+
+MIDI-CI is a high-level protocol that can talk with the MIDI device
+for the flexible profiles and configurations. It's represented in the
+form of special SysEx.
+
+For Linux implementations, the kernel supports the UMP transport and
+the encoding/decoding of MIDI protocols on UMP, while MIDI-CI is
+supported in user-space over the standard SysEx.
+
+As of this writing, only USB MIDI device supports the UMP and Linux
+2.0 natively. The UMP support itself is pretty generic, hence it
+could be used by other transport layers, although it could be
+implemented differently (e.g. as a ALSA sequencer client), too.
+
+The access to UMP devices are provided in two ways: the access via
+rawmidi device and the access via ALSA sequencer API.
+
+ALSA sequencer API was extended to allow the payload of UMP packets.
+It's allowed to connect freely between MIDI 1.0 and MIDI 2.0 sequencer
+clients, and the events are converted transparently.
+
+
+Kernel Configuration
+====================
+
+The following new configs are added for supporting MIDI 2.0:
+`CONFIG_SND_UMP`, `CONFIG_SND_UMP_LEGACY_RAWMIDI`,
+`CONFIG_SND_SEQ_UMP`, `CONFIG_SND_SEQ_UMP_CLIENT`, and
+`CONFIG_SND_USB_AUDIO_MIDI_V2`. The first visible one is
+`CONFIG_SND_USB_AUDIO_MIDI_V2`, and when you choose it (to set `=y`),
+the core support for UMP (`CONFIG_SND_UMP`) and the sequencer binding
+(`CONFIG_SND_SEQ_UMP_CLIENT`) will be automatically selected.
+
+Additionally, `CONFIG_SND_UMP_LEGACY_RAWMIDI=y` will enable the
+support for the legacy raw MIDI device for UMP Endpoints.
+
+
+Rawmidi Device with USB MIDI 2.0
+================================
+
+When a device supports MIDI 2.0, the USB-audio driver probes and uses
+the MIDI 2.0 interface (that is found always at the altset 1) as
+default instead of the MIDI 1.0 interface (at altset 0). You can
+switch back to the binding with the old MIDI 1.0 interface by passing
+`midi2_enable=0` option to snd-usb-audio driver module, too.
+
+The USB audio driver tries to query the UMP Endpoint and UMP Function
+Block information that are provided since UMP v1.1, and builds up the
+topology based on those information. When the device is older and
+doesn't respond to the new UMP inquiries, the driver falls back and
+builds the topology based on Group Terminal Block (GTB) information
+from the USB descriptor. Some device might be screwed up by the
+unexpected UMP command; in such a case, pass `midi2_probe=0` option to
+snd-usb-audio driver for skipping the UMP v1.1 inquiries.
+
+When the MIDI 2.0 device is probed, the kernel creates a rawmidi
+device for each UMP Endpoint of the device. Its device name is
+`/dev/snd/umpC*D*` and different from the standard rawmidi device name
+`/dev/snd/midiC*D*` for MIDI 1.0, in order to avoid confusing the
+legacy applications accessing mistakenly to UMP devices.
+
+You can read and write UMP packet data directly from/to this UMP
+rawmidi device. For example, reading via `hexdump` like below will
+show the incoming UMP packets of the card 0 device 0 in the hex
+format::
+
+ % hexdump -C /dev/snd/umpC0D0
+ 00000000 01 07 b0 20 00 07 b0 20 64 3c 90 20 64 3c 80 20 |... ... d<. d<. |
+
+Unlike the MIDI 1.0 byte stream, UMP is a 32bit packet, and the size
+for reading or writing the device is also aligned to 32bit (which is 4
+bytes).
+
+The 32-bit words in the UMP packet payload are always in CPU native
+endianness. Transport drivers are responsible to convert UMP words
+from / to system endianness to required transport endianness / byte
+order.
+
+When `CONFIG_SND_UMP_LEGACY_RAWMIDI` is set, the driver creates
+another standard raw MIDI device additionally as `/dev/snd/midiC*D*`.
+This contains 16 substreams, and each substream corresponds to a
+(0-based) UMP Group. Legacy applications can access to the specified
+group via each substream in MIDI 1.0 byte stream format. With the
+ALSA rawmidi API, you can open the arbitrary substream, while just
+opening `/dev/snd/midiC*D*` will end up with opening the first
+substream.
+
+Each UMP Endpoint can provide the additional information, constructed
+from the information inquired via UMP 1.1 Stream messages or USB MIDI
+2.0 descriptors. And a UMP Endpoint may contain one or more UMP
+Blocks, where UMP Block is an abstraction introduced in the ALSA UMP
+implementations to represent the associations among UMP Groups. UMP
+Block corresponds to Function Block in UMP 1.1 specification. When
+UMP 1.1 Function Block information isn't available, it's filled
+partially from Group Terminal Block (GTB) as defined in USB MIDI 2.0
+specifications.
+
+The information of UMP Endpoints and UMP Blocks are found in the proc
+file `/proc/asound/card*/midi*`. For example::
+
+ % cat /proc/asound/card1/midi0
+ ProtoZOA MIDI
+
+ Type: UMP
+ EP Name: ProtoZOA
+ EP Product ID: ABCD12345678
+ UMP Version: 0x0000
+ Protocol Caps: 0x00000100
+ Protocol: 0x00000100
+ Num Blocks: 3
+
+ Block 0 (ProtoZOA Main)
+ Direction: bidirection
+ Active: Yes
+ Groups: 1-1
+ Is MIDI1: No
+
+ Block 1 (ProtoZOA Ext IN)
+ Direction: output
+ Active: Yes
+ Groups: 2-2
+ Is MIDI1: Yes (Low Speed)
+ ....
+
+Note that `Groups` field shown in the proc file above indicates the
+1-based UMP Group numbers (from-to).
+
+Those additional UMP Endpoint and UMP Block information can be
+obtained via the new ioctls `SNDRV_UMP_IOCTL_ENDPOINT_INFO` and
+`SNDRV_UMP_IOCTL_BLOCK_INFO`, respectively.
+
+The rawmidi name and the UMP Endpoint name are usually identical, and
+in the case of USB MIDI, it's taken from `iInterface` of the
+corresponding USB MIDI interface descriptor. If it's not provided,
+it's copied from `iProduct` of the USB device descriptor as a
+fallback.
+
+The Endpoint Product ID is a string field and supposed to be unique.
+It's copied from `iSerialNumber` of the device for USB MIDI.
+
+The protocol capabilities and the actual protocol bits are defined in
+`asound.h`.
+
+
+ALSA Sequencer with USB MIDI 2.0
+================================
+
+In addition to the rawmidi interfaces, ALSA sequencer interface
+supports the new UMP MIDI 2.0 device, too. Now, each ALSA sequencer
+client may set its MIDI version (0, 1 or 2) to declare itself being
+either the legacy, UMP MIDI 1.0 or UMP MIDI 2.0 device, respectively.
+The first, legacy client is the one that sends/receives the old
+sequencer event as was. Meanwhile, UMP MIDI 1.0 and 2.0 clients send
+and receive in the extended event record for UMP. The MIDI version is
+seen in the new `midi_version` field of `snd_seq_client_info`.
+
+A UMP packet can be sent/received in a sequencer event embedded by
+specifying the new event flag bit `SNDRV_SEQ_EVENT_UMP`. When this
+flag is set, the event has 16 byte (128 bit) data payload for holding
+the UMP packet. Without the `SNDRV_SEQ_EVENT_UMP` bit flag, the event
+is treated as a legacy event as it was (with max 12 byte data
+payload).
+
+With `SNDRV_SEQ_EVENT_UMP` flag set, the type field of a UMP sequencer
+event is ignored (but it should be set to 0 as default).
+
+The type of each client can be seen in `/proc/asound/seq/clients`.
+For example::
+
+ % cat /proc/asound/seq/clients
+ Client info
+ cur clients : 3
+ ....
+ Client 14 : "Midi Through" [Kernel Legacy]
+ Port 0 : "Midi Through Port-0" (RWe-)
+ Client 20 : "ProtoZOA" [Kernel UMP MIDI1]
+ UMP Endpoint: ProtoZOA
+ UMP Block 0: ProtoZOA Main [Active]
+ Groups: 1-1
+ UMP Block 1: ProtoZOA Ext IN [Active]
+ Groups: 2-2
+ UMP Block 2: ProtoZOA Ext OUT [Active]
+ Groups: 3-3
+ Port 0 : "MIDI 2.0" (RWeX) [In/Out]
+ Port 1 : "ProtoZOA Main" (RWeX) [In/Out]
+ Port 2 : "ProtoZOA Ext IN" (-We-) [Out]
+ Port 3 : "ProtoZOA Ext OUT" (R-e-) [In]
+
+Here you can find two types of kernel clients, "Legacy" for client 14,
+and "UMP MIDI1" for client 20, which is a USB MIDI 2.0 device.
+A USB MIDI 2.0 client gives always the port 0 as "MIDI 2.0" and the
+rest ports from 1 for each UMP Group (e.g. port 1 for Group 1).
+In this example, the device has three active groups (Main, Ext IN and
+Ext OUT), and those are exposed as sequencer ports from 1 to 3.
+The "MIDI 2.0" port is for a UMP Endpoint, and its difference from
+other UMP Group ports is that UMP Endpoint port sends the events from
+the all ports on the device ("catch-all"), while each UMP Group port
+sends only the events from the given UMP Group.
+Also, UMP groupless messages (such as the UMP message type 0x0f) are
+sent only to the UMP Endpoint port.
+
+Note that, although each UMP sequencer client usually creates 16
+ports, those ports that don't belong to any UMP Blocks (or belonging
+to inactive UMP Blocks) are marked as inactive, and they don't appear
+in the proc outputs. In the example above, the sequencer ports from 4
+to 16 are present but not shown there.
+
+The proc file above shows the UMP Block information, too. The same
+entry (but with more detailed information) is found in the rawmidi
+proc output.
+
+When clients are connected between different MIDI versions, the events
+are translated automatically depending on the client's version, not
+only between the legacy and the UMP MIDI 1.0/2.0 types, but also
+between UMP MIDI 1.0 and 2.0 types, too. For example, running
+`aseqdump` program on the ProtoZOA Main port in the legacy mode will
+give you the output like::
+
+ % aseqdump -p 20:1
+ Waiting for data. Press Ctrl+C to end.
+ Source Event Ch Data
+ 20:1 Note on 0, note 60, velocity 100
+ 20:1 Note off 0, note 60, velocity 100
+ 20:1 Control change 0, controller 11, value 4
+
+When you run `aseqdump` in MIDI 2.0 mode, it'll receive the high
+precision data like::
+
+ % aseqdump -u 2 -p 20:1
+ Waiting for data. Press Ctrl+C to end.
+ Source Event Ch Data
+ 20:1 Note on 0, note 60, velocity 0xc924, attr type = 0, data = 0x0
+ 20:1 Note off 0, note 60, velocity 0xc924, attr type = 0, data = 0x0
+ 20:1 Control change 0, controller 11, value 0x2000000
+
+while the data is automatically converted by ALSA sequencer core.
+
+
+Rawmidi API Extensions
+======================
+
+* The additional UMP Endpoint information can be obtained via the new
+ ioctl `SNDRV_UMP_IOCTL_ENDPOINT_INFO`. It contains the associated
+ card and device numbers, the bit flags, the protocols, the number of
+ UMP Blocks, the name string of the endpoint, etc.
+
+ The protocols are specified in two field, the protocol capabilities
+ and the current protocol. Both contain the bit flags specifying the
+ MIDI protocol version (`SNDRV_UMP_EP_INFO_PROTO_MIDI1` or
+ `SNDRV_UMP_EP_INFO_PROTO_MIDI2`) in the upper byte and the jitter
+ reduction timestamp (`SNDRV_UMP_EP_INFO_PROTO_JRTS_TX` and
+ `SNDRV_UMP_EP_INFO_PROTO_JRTS_RX`) in the lower byte.
+
+ A UMP Endpoint may contain up to 32 UMP Blocks, and the number of
+ the currently assigned blocks are shown in the Endpoint information.
+
+* Each UMP Block information can be obtained via another new ioctl
+ `SNDRV_UMP_IOCTL_BLOCK_INFO`. The block ID number (0-based) has to
+ be passed for the block to query. The received data contains the
+ associated the direction of the block, the first associated group ID
+ (0-based) and the number of groups, the name string of the block,
+ etc.
+
+ The direction is either `SNDRV_UMP_DIR_INPUT`,
+ `SNDRV_UMP_DIR_OUTPUT` or `SNDRV_UMP_DIR_BIDIRECTION`.
+
+* For the device supports UMP v1.1, the UMP MIDI protocol can be
+ switched via "Stream Configuration Request" message (UMP type 0x0f,
+ status 0x05). When UMP core receives such a message, it updates the
+ UMP EP info and the corresponding sequencer clients as well.
+
+
+Control API Extensions
+======================
+
+* The new ioctl `SNDRV_CTL_IOCTL_UMP_NEXT_DEVICE` is introduced for
+ querying the next UMP rawmidi device, while the existing ioctl
+ `SNDRV_CTL_IOCTL_RAWMIDI_NEXT_DEVICE` queries only the legacy
+ rawmidi devices.
+
+ For setting the subdevice (substream number) to be opened, use the
+ ioctl `SNDRV_CTL_IOCTL_RAWMIDI_PREFER_SUBDEVICE` like the normal
+ rawmidi.
+
+* Two new ioctls `SNDRV_CTL_IOCTL_UMP_ENDPOINT_INFO` and
+ `SNDRV_CTL_IOCTL_UMP_BLOCK_INFO` provide the UMP Endpoint and UMP
+ Block information of the specified UMP device via ALSA control API
+ without opening the actual (UMP) rawmidi device.
+ The `card` field is ignored upon inquiry, always tied with the card
+ of the control interface.
+
+
+Sequencer API Extensions
+========================
+
+* `midi_version` field is added to `snd_seq_client_info` to indicate
+ the current MIDI version (either 0, 1 or 2) of each client.
+ When `midi_version` is 1 or 2, the alignment of read from a UMP
+ sequencer client is also changed from the former 28 bytes to 32
+ bytes for the extended payload. The alignment size for the write
+ isn't changed, but each event size may differ depending on the new
+ bit flag below.
+
+* `SNDRV_SEQ_EVENT_UMP` flag bit is added for each sequencer event
+ flags. When this bit flag is set, the sequencer event is extended
+ to have a larger payload of 16 bytes instead of the legacy 12
+ bytes, and the event contains the UMP packet in the payload.
+
+* The new sequencer port type bit (`SNDRV_SEQ_PORT_TYPE_MIDI_UMP`)
+ indicates the port being UMP-capable.
+
+* The sequencer ports have new capability bits to indicate the
+ inactive ports (`SNDRV_SEQ_PORT_CAP_INACTIVE`) and the UMP Endpoint
+ port (`SNDRV_SEQ_PORT_CAP_UMP_ENDPOINT`).
+
+* The event conversion of ALSA sequencer clients can be suppressed the
+ new filter bit `SNDRV_SEQ_FILTER_NO_CONVERT` set to the client info.
+ For example, the kernel pass-through client (`snd-seq-dummy`) sets
+ this flag internally.
+
+* The port information gained the new field `direction` to indicate
+ the direction of the port (either `SNDRV_SEQ_PORT_DIR_INPUT`,
+ `SNDRV_SEQ_PORT_DIR_OUTPUT` or `SNDRV_SEQ_PORT_DIR_BIDIRECTION`).
+
+* Another additional field for the port information is `ump_group`
+ which specifies the associated UMP Group Number (1-based).
+ When it's non-zero, the UMP group field in the UMP packet updated
+ upon delivery to the specified group (corrected to be 0-based).
+ Each sequencer port is supposed to set this field if it's a port to
+ specific to a certain UMP group.
+
+* Each client may set the additional event filter for UMP Groups in
+ `group_filter` bitmap. The filter consists of bitmap from 1-based
+ Group numbers. For example, when the bit 1 is set, messages from
+ Group 1 (i.e. the very first group) are filtered and not delivered.
+ The bit 0 is used for filtering UMP groupless messages.
+
+* Two new ioctls are added for UMP-capable clients:
+ `SNDRV_SEQ_IOCTL_GET_CLIENT_UMP_INFO` and
+ `SNDRV_SEQ_IOCTL_SET_CLIENT_UMP_INFO`. They are used to get and set
+ either `snd_ump_endpoint_info` or `snd_ump_block_info` data
+ associated with the sequencer client. The USB MIDI driver provides
+ those information from the underlying UMP rawmidi, while a
+ user-space client may provide its own data via `*_SET` ioctl.
+ For an Endpoint data, pass 0 to the `type` field, while for a Block
+ data, pass the block number + 1 to the `type` field.
+ Setting the data for a kernel client shall result in an error.
+
+* With UMP 1.1, Function Block information may be changed
+ dynamically. When the update of Function Block is received from the
+ device, ALSA sequencer core changes the corresponding sequencer port
+ name and attributes accordingly, and notifies the changes via the
+ announcement to the ALSA sequencer system port, similarly like the
+ normal port change notification.
