ALSA: firewire-tascam: add streaming functionality This commit adds streaming functionality for both direction. To utilize the sequence of the number of data blocks in packets, full duplex with synchronization is applied. Besides, TASCAM FireWire series allows drivers to decide which PCM data channels are enabled. For convenience, this driver always enable whole the data channels.

ALSA: firewire-tascam: add support for incoming MIDI messages by asynchronous transaction TASCAM FireWire series use asynchronous transaction to transfer MIDI messages. The transaction is sent to a registered address. This commit supports the incoming MIDI messages. The messages in the transaction include some quirks: * Two quadlets are used for one MIDI message and one timestamp. * Usually, the first byte of the first quadlet includes MIDI port and MSB 4 bit of MIDI status. For system exclusive message, the first byte includes MIDI port and 0x04, or 0x07 in the end of the message. * The rest of the first quadlet includes MIDI bytes up to 3. * Several set of MIDI messages and timestamp can be transferred in one block transaction, up to 8 sets. I note that TASCAM FireWire series ignores ID bytes of system exclusive message. When receiving system exclusive messages with ID bytes on physical MIDI bus, the series transfers the messages without ID bytes on IEEE 1394 bus, and vice versa.

ALSA: firewire-tascam: add support for MIDI functionality In former commits, this driver got functionalities to transfer/receive MIDI messages to/from TASCAM FireWire series. This commit adds some ALSA MIDI ports to enable userspace applications to use the functionalities. I note that this commit doesn't support virtual MIDI ports which console models support. A physical controls can be assigned to a certain MIDI ports including physical and virtual. But the way is not clear.

ALSA: firewire-tascam: add skeleton for TASCAM FireWire series This commit adds a new driver for TASCAM FireWire series. In this commit, this driver just creates/removes card instance according to bus event. More functionalities will be added in following commits. TASCAM FireWire series consists of: * PDI 1394P23 for IEEE 1394 PHY layer * PDI 1394L40 for IEEE 1394 LINK layer and IEC 61883 interface * XILINX XC9536XL * XILINX Spartan-II XC2S100 * ATMEL AT91M42800A Ilya Zimnovich had investigated TASCAM FireWire series in 2011, and discover some features of his FW-1804. You can see a part of his research in FFADO project. http://subversion.ffado.org/wiki/Tascam A part of my work are based on Ilya's investigation, while this series doesn't support the FW-1804, because of a lack of config ROM information and its protocol detail, especially for PCM channels. I observed that FW-1884 and FW-1082 don't work properly with 1394 OHCI controller based on VT6315. The controller can actually communicate packets to these models, while these models generate no sounds. It may be due to the PHY/LINK layer issues. Using 1394 OHCI controller produced by the other vendors such as Texas Instruments may work. Or adding another node on the bus.
