[alsa-devel] [PATCH 52/52] bebob: Add support for M-Audio special Firewire series

This commit is optional. The aim of this commit is to show firmware
quirks for some M-Audio devices.
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 some model specific members in 'struct
snd_bebob' and model specific functions. Some parameters are write-only so this
commit also adds control interface for them.
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 have a time not to respond transaction. In this reason, this driver
often fail to handle them.
This module don't support to upload firmware.
