ALSA: bebob: improve signal mode detection for clock source
With BeBoB version 3, current ALSA BeBoB driver detects the type of current clock signal source wrongly. This is due to a lack of proper implementation to parse the information.
This commit renews the parser. As a result, this driver detects SYT-Match clock signal, thus it can start streams with two modes; SYT-Match mode and the others. SYT-Match mode will be supported in future commits.
There's a constrain about detected internal/external clock source. When detecting external clock source, this driver allows userspace applications to use current sampling rate only. This is due to consider abour synchronization to external clock sources such as S/PDIF, ADAT or word-clock.
According to several information from some devices, I guesss that the internal clock of most devices synchronize to IEEE 1394 cycle start packet. In this case, by a usual way, it's detect as 'Sync type of output Music Sub-Unit' connected to 'Sync type of PCR output Unit (oPCR)', and this driver judges it as internal clock. Therefore, userspace applications is allowed to request arbitrary supported sampling rates.
On the other hand, several devices based on BeBoB version 3 have additional internal clock. In this case, by a usual way, it's detect as 'Sync/Additional type of External input Unit'. Unfortunately, there's no way to distinguish this sync type from the other external clock sources such as word-clock. In this case, this driver handles it as external and userspace applications is forced to use current sampling rate.
I note that when the source of clock is detected as 'Isochronous stream type of input PCR[0]', it's under 'SYT-Match' mode. In this mode, the synchronization clock is generated according to SYT-series in received packets. In this case, this driver generates the series by myself. I experienced this mode often make the device silent suddenly during playbacking. This means that the mode is easy to lost synchronization.

ALSA: firewire/bebob: Add a workaround for M-Audio special Firewire series
In post commit, a quirk of this firmware about transactions is reported. This commit apply a workaround for this quirk.
They often fail transactions due to gap_count mismatch. This state is changed by generating bus reset.
The fw_schedule_bus_reset() is an exported symbol in firewire-core. But there are no header for public. This commit moves its prototype from drivers/firewire/core.h to include/linux/firewire.h.
This mismatch still affects bus management before generating this bus reset. It still takes a time to call driver's probe() because transactions are still often failed.

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.

ALSA: bebob: Add support for M-Audio usual Firewire series
This commit allows this driver to support some models which M-Audio produces with DM1000/DM1000E with usual firmware. They are: - Firewire 410 - Firewire AudioPhile - Firewire Solo - Ozonic - NRV10 - FirewireLightBridge
According to a person who worked in BridgeCo, some models are produced with 'Pre-BeBoB'. This means that these products were released before BeBoB was officially produced, and later BeBoB specification was formed. So these models have some quirks.
M-Audio usual firmware quirks: - Just after powering on, 'Firewire 410' waits 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. - 'Firewire Audiophile' also waits to download firmware but its vendor id/model id is the same as the one after loading firmware. - The information of channel mapping for MIDI conformant data channel is invalid against BridgeCo specification.
This commit adds some codes for these quirks but don't support to upload firmware.
This commit also adds specific operations to get metering information. The metering information also includes status of clock synchronization if the model supports to switch source of clock.
The specification of FirewireLightBridge is unknown. So in this time, normal operations are applied for this model.

ALSA: bebob/firewire-lib: Add a quirk for discontinuity at bus reset
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.

ALSA: bebob: share PCM buffer size for both direction This commit allows ALSA bebob driver to share PCM buffer size for both capture and playback PCM substream. When AMDTP domain starts for one of the PCM substream, buffer size of the PCM substream is stores to AMDTP domain structure. Some AMDTP streams have already run with the buffer size when another PCM substream starts, therefore the PCM substream has a constraint to its buffer size.
