3a9236e972 ALSA: dice: fix wrong packet parameter for Alesis iO26
At higher sampling rate (e.g. 192.0 kHz), Alesis iO26 transfers 4 data
channels per data block in CIP.

Both iO14 and iO26 have the same contents in their configuration ROM.
For this reason, ALSA Dice driver attempts to distinguish them according
to the value of TX0_AUDIO register at probe callback. Although the way is
valid at lower and middle sampling rate, it's lastly invalid at higher
sampling rate because because the two models returns the same value for
read transaction to the register.

In the most cases, users just plug-in the device and ALSA dice driver
detects it. In the case, the device runs at lower sampling rate and
the driver detects expectedly. For this reason, this commit leaves the
way to detect as is.

e1a00b5b25 ALSA: firewire-tascam: check intermediate state of clock status and retry
2 bytes in MSB of register for clock status is zero during intermediate
state after changing status of sampling clock in models of TASCAM FireWire
series. The duration of this state differs depending on cases. During the
state, it's better to retry reading the register for current status of
the clock.

In current implementation, the intermediate state is checked only when
getting current sampling transmission frequency, then retry reading.
This care is required for the other operations to read the register.

This commit moves the codes of check and retry into helper function
commonly used for operations to read the register.

8d0d5c3fa1 ALSA: firewire-lib: remove WARN_ON() at destruction of AMDTP domain
The destructor of AMDTP domain has WARN_ON() for the list of associated
AMDTP stream. Although this reminds a case that developers forget to
program consumer drivers to stop AMDTP domain, it hits when AMDTP domain
is not initialized yet. This occurs when initialization of sound card
fails as well and it's superfluous.

This commit removes the WARN_ON. Although the API to AMDTP domain does
nothing, it's left for future usage.

e6e2fe2b8f ALSA: firewire-tascam: add note for FE-8
TASCAM FE-8 is the rest of model in TASCAM FireWire series. This device
has no functionality to process audio signal and MIDI messages. Instead,
it transfers control messages to host system corresponding to operations
for some faders, buttons and knobs on its surface.

Unlike the other devices in this series, the control messages are
transmitted by asynchronous transactions. Some registers of device are
used for registration of destination address for the transaction. The
transaction includes quadlet-aligned data up to 32 quadlets.

Userspace applications can receive the transaction and parse it for
control message via Linux FireWire subsystem, without any support by
ALSA firewire-tascam driver. Therefore the driver gives no support
for it.

This commit removes placeholder for FE-8 and add some comment for its
functionalities as notes.

6af86bdb8a ALSA: firewire-motu: add support for MOTU 4pre
MOTU 4pre was launched in 2012 by MOTU, Inc. This commit allows userspace
applications can transmit and receive PCM frames and MIDI messages for
this model via ALSA PCM interface and RawMidi/Sequencer interfaces.

The device supports MOTU protocol version 3. Unlike the other devices, the
device is simply designed. The size of data block is fixed to 10 quadlets
during available sampling rates (44.1 - 96.0 kHz). Each data block
includes 1 source packet header, 2 data chunks for messages, 8 data chunks
for PCM samples and 2 data chunks for padding to quadlet alignment. The
device has no MIDI, optical, BNC and AES/EBU interfaces.

Like support for the other MOTU devices, the quality of playback sound
is not enough good with periodical noise yet.

04130cf8e2 ALSA: firewire-lib: add list of packet descriptor
In current implementation of ALSA IEC 61883-1/6 packet streaming engine,
16 packets are handled in one interrupt of isochronous context of OHCI
1394.

Overall packet processing runs for each. However, this is not better in
a point to split the processing into several parts.

This commit is an attempt to add intermediate representation for
parameters required for the parts.

In a previous commit, the variable passed from packet streaming layer
for syt variable is useless. This commit obsoletes it.

In my future work, the syt information is passed to data block processing
layer by another way.

3baf30532f ALSA: firewire-lib: add syt_override member for some protocols
Some protocols don't use syt field of CIP header to represent
presentation timestamp. For such protocol, ALSA IEC 61883-1/6
packet streaming engine uses a pointer into local variable for
the value of syt to call data block processing layer. However,
it can decide the value when initializing packet streaming
layer.

This commit adds 'syt_override' member for packet streaming
layer.
