ALSA: firewire-tascam: add data block processing layer TASCAM FireWire series uses non-blocking transmission for AMDTP packet streaming, while the format of data blocks is unique. The CIP headers includes specific value in FMT field and no SYT information. In transmitted packets, the first data channel represents event counter, and the last data channel has status and control information. The rest has 24bit PCM samples with right padding. In received packets, all of data channels include 16, 24, 32bit PCM samples. There's no other kind of information. This commit adds support for this protocol. For convenience, the size of PCM samples in outgoing packet is limited by 16 and 24bit. The status and control information will be supported in future commits.

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.
