13b8b78c7f ALSA: oxfw: copy handlers of asynchronous transaction for MIDI capture
This commit copies some functions of asynchronous transactions for MIDI
capture, to merge scs1x module. The features of payload in asynchronous
transaction are:

 * System exclusive messages for SCS.1 are encoded without ID data. In
   this encoding scheme, 4 bits in LSB are available. The bits are squashed
   in payload byte. Thus, one payload byte transfers two MIDI messages.
 * The first byte of payload byte means:
  * 0x00: depending on second payload byte
   * 0xf9: including escaped system exclusive messages for SCS.1, up to
     3 byte (= 6 MIDI messages)
   * the others: including MIDI 1.0 messages
  * the others: including escaped system exclusive messages for SCS.1, up
    to 64 bytes

e3315b439c ALSA: oxfw: allocate own address region for SCS.1 series
When physical controls on SCS.1 models are operated, the models transfer
MIDI messages in asynchronous transactions on IEEE 1394 bus. The models
have a register to have an address for the transactions, and drivers
can register own address for this purpose.

This commit keeps a region of address, registers it and adds a handler for
the transactions.

3f47152a1c ALSA: oxfw: add scs1x layer
Stanton Controllers and Systems 1 (SCS.1) series is supported by ALSA
scs1x driver. This driver just supports MIDI functionality. On the other
hand, models in this series are based on OXFW971 and ALSA OXFW driver can
support them.

SCS.1 series has MIDI functionality to control its surface state such as
LED lighting. When operating physical knobs and faders, the models
generate MIDI messages. These MIDI messages are transferred by asynchronous
transactions. These transactions are really model-specific and ALSA OXFW
driver requires the functionality so as scs1x module implements.

This commit adds scs1x layer as a preparation to merge scs1x driver to
oxfw driver.

eab8e4e461 ALSA: oxfw: change function prototype for AV/C Audio Subunit command
ALSA OXFW driver uses AV/C Audio Subunit commands to control some models.
The commands get/set the state of Feature function block of the subunit.
The commands are not specific to OXFW, thus there's a possibility to use
them in the other drivers.

Currently, helper functions for the commands require 'struct snd_oxfw',
although, it's not necessarily required. It's better to change prototype
of the functions without the structure for future use.

This commit changes the prototype.

f3a0e32a6f ALSA: oxfw: rename a file for control elements so that it's for model-specific
In ALSA firewire stack, drivers basically has no control elements. This
is due to the fact that each model has own functionality even if they use
the same communication chipset. Implementing all of the functionalities in
kernel space unreasonably increases our efforts to maintain the stack. In
most case, these functionalities can be implemented in userspace via Linux
fw character devices.

However, ALSA OXFW driver has control elements comes from old
firewire-speakers driver. Adding the elements is in a file names as
'oxfw-control.c', while the elements are really model-specific. The
name is confusing because it gives an idea to handle control elements
for all of OXFW-based models.

This commit renames the file so that it's just for models supported by
old firewire-speakers driver.

5d5563b14f ALSA: dice: fix detection of Loud devices
Commit a471fcde8c ("ALSA: dice: fix detection of Weiss devices") adds
a quirk of Weiss models. According to users' reports, Loud models also
have the similar quirk. They have 0x10 in the category field.

This commit adds support for Mackie Onyx Blackbird and Onyx-i series.
As long as I know, Dice-based models produced by
Focusrite/Alesis/PreSonus/M-Audio/TC Electronic have default value (0x04)
in their category field, thus it may be reasonable to add a condition
statement for Loud models, instead of removing the check of category value.

c5fcee0373 ALSA: firewire-digi00x: add MIDI operations for MIDI control port
Digi 002/003 family has two types of MIDI port; one is for physical MIDI
port and another is for MIDI control message. The former is transferred in
isochronous packet, and the latter is transferred by asynchronous
transaction. These transmission mechanisms are completely different, while
current ALSA digi00x driver defines a set of operations for them with
several condition statements. As a result, codes for the operation are
messy.

This commit adds a set of MIDI operation for control MIDI ports. In later

bb71da4346 ALSA: oxfw: support more MIDI ports
In IEC 61883-6, sequence multiplexing is applied to MIDI conformant data
channel. As a result, eight MIDI data streams are included in the channel.
Although ALSA AM824 data block processing layer implements this
multiplexing, current OXFW driver doesn't utilize it due to wrong
calculation of MIDI ports.

This commit fixes this bug to add proper calculation. Although this commit
allows to use 8 MIDI data streams, the number of available MIDI ports is
limited by the number of ALSA MIDI ports added by the driver.

e65e2cb99e ALSA: firewire-tascam: Turn on/off FireWire LED
TASCAM FireWire series has some LEDs on its surface. These LEDs can be
turned on/off by receiving asynchronous transactions to a certain
address. One of the LEDs is labels as 'FireWire'. It's better to light it
up when this driver starts to work. Besides, the LED for 'FireWire' is
turned off at bus reset.

This commit implements this idea.

0db18e7eec ALSA: firewire-tascam: add support for MIDI functionality
In former commits, this driver got functionalities to transfer/receive
MIDI messages to/from TASCAM FireWire series.

This commit adds some ALSA MIDI ports to enable userspace applications
to use the functionalities.

I note that this commit doesn't support virtual MIDI ports which console
models support. A physical controls can be assigned to a certain MIDI
ports including physical and virtual. But the way is not clear.

3beab0f844 ALSA: firewire-tascam: add support for outgoing MIDI messages by asynchronous transaction
TASCAM FireWire series use asynchronous transaction to receive MIDI
messages. The transaction should be sent to a certain address.

This commit supports the outgoing MIDI messages. The messages in the
transaction includes some quirks:
 * One MIDI message is transferred in one quadlet transaction, except for
   system exclusives.
 * MIDI running status is not allowed, thus transactions always include
   status byte.
 * The basic data format is the same as transferring MIDI messages
   supported in previous commit.

107cc0129a ALSA: firewire-tascam: add support for incoming MIDI messages by asynchronous transaction
TASCAM FireWire series use asynchronous transaction to transfer MIDI
messages. The transaction is sent to a registered address.

This commit supports the incoming MIDI messages. The messages in the
transaction include some quirks:
 * Two quadlets are used for one MIDI message and one timestamp.
 * Usually, the first byte of the first quadlet includes MIDI port and MSB
   4 bit of MIDI status. For system exclusive message, the first byte
   includes MIDI port and 0x04, or 0x07 in the end of the message.
 * The rest of the first quadlet includes MIDI bytes up to 3.
 * Several set of MIDI messages and timestamp can be transferred in one
   block transaction, up to 8 sets.

I note that TASCAM FireWire series ignores ID bytes of system exclusive
message. When receiving system exclusive messages with ID bytes on physical
MIDI bus, the series transfers the messages without ID bytes on IEEE 1394
bus, and vice versa.

e8bd577ae6 ALSA: firewire-digi00x: add support for MIDI ports for physical controls
In former commits, asynchronous transactions are supported for physical
controls. This commit adds a pair of MIDI ports for them.

This driver already adds diferrent number of ALSA MIDI ports for physical
MIDI ports, and the number of in/out ports are different. As seeing as
'amidi' program in alsa-utils package, a pair of in/out MIDI ports is
expected with the same name. Therefore, this commit adds a pair of new
ports to the first.

b47f525f76 ALSA: firewire-digi00x: add support of asynchronous transaction for outgoing MIDI messages to physical controls
In previous commit, asynchronous transaction for incoming MIDI messages
from physical controls is supported. The physical controls may be
controlled by receiving MIDI messages at a certain address.

This commit supports asynchronous transaction for this purpose.

3646a54acd ALSA: firewire-digi00x: add support of asynchronous transaction for incoming MIDI messages from physical controls
Digi 00x series has two types of model; rack and console. The console
models have physical controls. The model can transmit control messages.
These control messages are transferred by asynchronous transactions to
registered address.

This commit supports the asynchronous transaction.

9fbfd38b20 ALSA: firewire-digi00x: add support for MIDI ports corresponding to isochronous packet streaming
This commit adds MIDI functionality to capture/playback MIDI messages
from/to physical MIDI ports. These messages are transferred in isochronous
packets.

When no substreams request AMDTP streams to run, this driver starts the
streams at current sampling rate. When other substreams start at different
sampling rate, the streams are stopped temporarily, then start again at
requested sampling rate. This operation can generate missing MIDI bytes,
thus it's preferable to start PCM substreams at favorite sampling rate in
advance.

Digi 002/003 console also has a set of MIDI port for physical controls.
These ports are added in later commits.

9dc5d31cdc ALSA: firewire-digi00x: handle MIDI messages in isochronous packets
In Digi 002/003 protocol, MIDI messages are transferred in the last data
channel of data blocks. Although this data channel has a label of 0x80,
it's not fully MIDI conformant data channel especially because the Counter
field always zero independently of included MIDI bytes. The 4th byte of
the data channel in LSB tells the number of included MIDI bytes. This byte
also includes the number of MIDI port. Therefore, the data format in this
data channel is:
 * 1st: 0x80 as label
 * 2nd: MIDI bytes
 * 3rd: 0 or MIDI bytes
 * 4th: the number of MIDI byte and the number of MIDI port

This commit adds support of MIDI messages in data block processing layer.

Like AM824 data format, this data channel has a capability to transfer
more MIDI messages than the capability of phisical MIDI bus. Therefore, a
throttle for data rate is  required to prevent devices' internal buffer to
overflow.
