ALSA: 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 to 'struct snd_bebob' and some model specific functions. Some parameters are write-only so this commit also adds control interface for applications to set 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. - After booting up, they often fail to send response against driver's request due to mismatch of gap_count. This module don't support to upload firmware.
