bebob: Add PCM interface

This commit adds the functionality to capture/playback PCM samples.

PCM samples are multiplexed/demultiplexed into AMDTP stream safely with stream
helper functions.
bebob: Add hwdep interface to lock/unlock streaming

This is for mixer/control application in user land. The application can
lock/unlock kernel streaming or get notification at starting/stopping kernel
streaming to use hwdep interface.
bebob: Prepare for device specific operations

This commit is for some devices designed for semi-professional use. They have
some model specific functionality and quirks.

Many functionality should be implemented in user land. Then this commit adds
functionality related to stream such as sampling frequency or clock source. And
some device need cue to load firmware. This commit adds this mechanism. For
debugging, this commit adds the functionality to get metering information if
it's available.

To help these functionalities, this commit adds some AV/C commands in 'AV/C
Audio Subunit Specification (1394TA)' and 'Connection and Compatibility
Management(1394TA)'.
bebob: Add support for M-Audio Firewire series

This commit allows this driver to support all of models which M-Audio produces
with BeBoB chipset. They are:
 - Firewire Solo
 - Firewire AudioPhile
 - Firewire 410
 - Firewire 1814
 - Ozonic
 - NRV10
 - ProjectMix I/O
 - FirewireLightBridge

This commit adds M-Audio specific operations, quirks and functionalities. They
are categorized to three parts.

1. send cue to load firmware
This is for 'Firewire Audiophile', 'Firewire410', 'Firewire1814' and
'ProjectMix I/O'. With firmware version 5058 or later, they wait to receive a
cue to load firmware just after powering on. With less firmware version, they
wait to upload firmware binary blob so this driver can't handle this versions.
This functionality can be implemented in user land but currently in kernel land
for my convinience.

2. switching source of clock
This if for 'Firewire Solo', 'Firewire Audiophile', 'Firewire410',
'Firewire1814' and'ProjectMix I/O'. They can switch source of clock with signal
source command but the value of parameters is a bit different.

3. handling metering information
This is all of models, mainly for my debugging. This information includes
information for clock synchronization.

Firewire1814 and ProjectMix I/O has heavily customized BeBoB chipset. The usual
operation to handle BeBoB chipset cannot be applied for them. For this reason,
this commit add some model specific members in 'struct snd_bebob' and model
specific functions.
bebob: Add support for Focusrite Saffire/SaffirePro series

This commit allows this driver to support all of models which Focusrite
produces with BeBoB chipset. They are:
 - Saffire
 - Saffire LE
 - SaffirePro 10 I/O
 - SaffirePro 26 I/O

This commit adds Focusrite specific operations, quirks for its four
functionalities.

1. Switching source of clock
2. Change sampling frequency
3. Check clock synchronization
4. Get metering information

The driver uses these functionalities to read/write specific address by async
transaction.
bebob: Add support for Terratec PHASE series

This commit allows this driver to support all of models which Terratec produced
with BeBoB chipset. They are:
 - PHASE 24 FW
 - PHASE X24 FW
 - PHASE 88 Rack FW

This commit adds Terratec specific operations, quirks for three functionalities.

1. Switching source of clock
2. Change sampling frequency
3. Check clock synchronization

The driver uses these functionalities with AV/C vendor specific commands and
AV/C Audio Subunit commands.
bebob: Add support for Yamaha GO series

This commit allows this driver to support all of models which Yamaha produced
with BeBoB chipset. They are:
 - GO44
 - GO46

This commit adds Yamaha specific operations, quirks for three functionalities.

1. Switching source of clock
2. Detecting signal in digital input
3. Check clock synchronization

The driver uses these functionalities with AV/C vendor specific commands and
AV/C Audio Subunit commands.
fireworks: Add skelton for Echo Audio Fireworks based devices

This commit add a new driver with no functionality. This driver just reacts to
Firewire bus events and create/remove card instance.

Current supported devices:
 - Mackie Onyx 400F/1200F
 - Echo AudioFire8(until 2009 July)/AudioFire12
 - Echo AudioFire2/4/8(since 2009 July)/Pre8
 - Echo Fireworks 8/HDMI
 - Gibson RIP/GoldTop
fireworks: Add Echo Fireworks Command and Response

Fireworks uses its own system to command/response. Previously this is over
AV/C vendor dependent command but recent firmware don't use this type. Then
command to and response from specific addresses.

The address to receive response give us an issue. When this driver allocate its
own callback function into the address, then user-land implement cannot allocate
its own callback function via Juju interface. Currently this commit don't solve
this issue. This issue must be resolved in future.
fireworks: Add stream and connection management

Fireworks transmit/receive AMDTP stream with a few quirks and manage the
connection by CMP.
fireworks: Add proc interface for debugging

This commit add proc interface to output infomation for debugging.
 - hardware capabilities
 - clock
 - meters
fireworks: Add control interface

Currently supported controls are:
 - switching source of clock
 - change sampling rate
 - change S/PDIF format
 - change Digital interface mode

They are mainly for my debugging.
fireworks: Add MIDI interface

This commit adds the functionality to capture/playback MIDI message. MIDI
message is multiplexed/demultiplexed into AMDTP stream.
fireworks: Add PCM interface

This commit adds the functionality to capture/playback PCM samples.

PCM samples are multiplexed/demultiplexed into AMDTP stream safely with stream
helper functions.
fireworks: Add hwdep interface

This is for mixer/control application in user land. The application can
lock/unlock kernel streaming or get notification at starting/stopping kernel
streaming to use hwdep interface.
