[alsa-devel] [PATCH 39/39] bebob: Add support for M-Audio special Firewire series

This commit allows this driver to support some models which M-Audio produces
with DM1000 but its firmware is special. They are:
- Firewire 1814
- ProjectMix I/O
They have heavily customized firmware. The usual operations can't be applied to
them. For this reason, this commit adds a model specific member in 'struct
snd_bebob' and some model specific functions. Some parameters are write-only so
this commit also adds control interface for applications.
M-Audio special firmware quirks:
- Just after powering on, they wait to download firmware. This state is
changed when receiving cue. Then bus reset is generated and the device is
recognized as a different model with the uploaded firmware.
- They don't respond against BridgeCo AV/C extension commands. So drivers
can't get their stream formations and so on.
- They do not start to transmit packets only by establishing connection but
also by receiving SIGNAL FORMAT command.
- They often handle requests without responding. In this reason, this driver
often fail to handle them correctly.
This module don't support to upload firmware.
Here are three examples of transactions between BeBoB driver and M-Audio
Firewire 1814. An fallback at timeout in the operations for CMP was already
added by previous commit. But for isochronous resource management, no fallbacks
are added. Further works are needed for Linux Firewire Subsystem.
