Takashi Sakamoto 6d5a2dda9b ALSA: firewire-motu: add support for MOTU 896 mk3 FireWire and Hybrid
Mark of the Unicorn released 896 mk3 FireWire in 2008 as part of the third
generation of its FireWire series. In 2011, 896 mk3 hybrid was released to
support USB protocol.

It supports sampling transfer frequency up to 192.0 kHz. The packet
format differs depending on both of current sampling transfer frequency
and the type of signal in optical interfaces. The model supports
transmission of PCM frames as well as MIDI messages.

The 896 mk3 FireWire consists of below ICs:

 * Texas Instruments TSB41AB2
 * Xilinx Spartan-3A FPGA, XC3S500E
 * Texas Instruments TMS320C6722
 * Microchip (Atmel) AT91SAM SAM7S256

It supports sampling transfer frequency up to 192.0 kHz. The packet
format differs depending on both of current sampling transfer frequency
and the type of signal in two pairs of optical interfaces. The model
supports transmission of PCM frames, while has no port for MIDi messages.

The model supports command mechanism to configure internal DSP. Hardware
meter information is available in the first 2 chunks of each data block
of tx packet.

This commit adds support for it. The 896 mk3 FireWire is just tested, but
the 896 mk3 Hybrid is not yet.
