This commit allows this driver to support all of models which Focusrite
produces with DM1000/BeBoB. They are:
- Saffire
- Saffire LE
- SaffirePro 10 I/O
- SaffirePro 26 I/O
This commit adds Focusrite specific operations:
1. Get source of clock
2. Get/Set sampling frequency
3. Get metering information
The driver uses these functionalities to read/write specific address by async
transaction.

This commit allows this driver to support all of models which Yamaha produced
with DM1000/BeBoB. They are:
- GO44
- GO46
This commit adds Yamaha specific operations. To get source of clock, AV/C Audio
Subunit command is used.
I note that their appearances are similar to some models of TerraTec; 'Go44' is
similar to 'PHASE 24 FW' and 'GO46' is similar to 'PHASE X24 FW'. But their
combination of Audio/Music subunits is a bit different.

This commit allows this driver to support all of models which Terratec produced
with DM1000/BeBoB. They are:
- PHASE 24 FW
- PHASE X24 FW
- PHASE 88 Rack FW
- EWS MIC2
- EWS MIC4
- Aureon 7.1 Firewire
For Phase series, this commit adds a Terratec specific operation. To get source
of clock. AV/C Audio Subunit command is used.
For EWS series and Aureon, this module uses normal operations.

This commit is for some devices which have its own operations or quirks.
Many functionality should be implemented in user land. Then this commit adds
functionality related to stream such as sampling frequency or clock source. For
help to debug, this commit adds the functionality to get metering information
if it's available.
To help these functionalities, this commit adds some AV/C commands defined in
'AV/C Audio Subunit Specification (1394TA).

This interface is designed for mixer/control application. By using hwdep
interface, the application can get information about firewire node, can
lock/unlock kernel streaming and can get notification at starting/stopping
kernel streaming.

This commit adds a functionality to capture/playback PCM samples.
When AMDTP stream is already running for PCM or the source of clock is not
internal, available sampling rate is limited at current one.

This commit adds a functionality to capture/playback MIDI messages.
When no AMDTP streams are running, this module starts AMDTP stream at current
sampling rate for MIDI substream.

Normal BeBoB firmware has a quirk. When receiving bus reset, it transmits
packets with discontinuous value in dbc field.
This causes two situation, one is to abort streaming by firewire-lib as a
result of detecting the discontinuity. Another is to call driver's .update()
because of bus reset. These two is generated independently. (The former
depends on isochronous stream and the latter depends on IEEE1394 bus driver.)
When BeBoB driver works with XRUN-recoverable applications, this situation
looks like stream_start_duplex() call followed by stream_update_duplex() call
because applications will call snd_pcm_prepare() immediately at XRUN.
To update connections and streams at first, this commit use completion. When
queueing error occurs, stream_start_duplex() is forced to wait maximum
1000msec. During this, when .update() is called, the completion is waken and
stream_start_duplex() is processed without breaking connections.
At bus reset, stream_start_duplex() shouldn't break/establish connections and
stream_update_duplex() should update connections because a caller of
fw_iso_resources_allocate() is responsible for calling
fw_iso_resources_update() on bus reset.
This commit also adds a flag, which has an effect to skip checking continuity
for first packet. This flag is useful for BeBoB quirk to start handling packets
during streaming.

This commit adds management functionality for connections and streams.
BeBoB uses CMP to manage connections and uses AMDTP for streams.
This commit also adds some BridgeCo's AV/C extension commands. There are some
BridgeCo's AV/C extension commands but this commit just uses below commands
to get device's capability and status:
1.Extended Plug Info commands
- Plug Channel Position Specific Data
- Plug Type Specific Data
- Cluster(Section) Info Specific Data
- Plug Input Specific Data
2.Extended Stream Format Information commands
- Extended Stream Format Information Command - List Request
For Extended Plug Info commands for Cluster Info Specific Data, I pick up
'section' instead of 'cluster' from document to prevent from misunderstanding
because 'cluster' is also used in IEC 61883-6.
