ALSA: firewire-motu: add support for MOTU 828mk2 as a model with protocol version 2 MOTU 828mk2 is one of second generation in MOTU FireWire series, produced in 2003. This model consists of four chips: * TI TSB41AB2 (Physical layer for IEEE 1394 bus) * PDI 1394L40BE (Link layer for IEEE 1394 bus and packet processing layer) * ALTERA ACEX 1K EP1K30 Series FPGA (Data block processing layer) * TI TMS320VC5402 (Digital signal processing) This commit adds a support for this model, with its unique protocol as version 2. The features of this protocol are: * Support data chunks for status and control messages for both directions. * Support a pair of MIDI input/output. * Support a data chunk for mic/instrument independent of analog line in. * Support a data chunk for playback return. * Support independent data chunks for S/PDIF of both optical/coaxial interfaces. * Support independent data chunks for each of main out and phone out. Status of clock is configured by write transactions to 0x'ffff'f000'0b14. Modes of optical interfaces are configured by write transactions to 0x'ffff'f000'0c04.

ALSA: firewire-motu: add support for MOTU 828mk3 (FireWire/Hybrid) as a model with protocol version 3 MOTU 828mk3 (FireWire/Hybrid) is one of third generation in MOTU FireWire series, produced in 2008/2014. This model consists of three chips for functionality on IEEE 1394 bus: * TI TSB41AB2 (Physical layer for IEEE 1394 bus) * Xilinx Spartan-3E FPGA Family (Link layer for IEEE 1394 bus, packet processing and data block processing layer) * TI TMS320C6722 (Digital signal processing) This commit adds a support for this model, with its unique protocol as version 3. This protocol has some additional features to protocol version 2. * Support several optical interfaces. * Support a data chunk for return of reverb effect. * Have a quirk of tx packets. * Support heartbeat asynchronous transaction. In this protocol, series of transferred packets has some quirks. Below fields in CIP headers of the packets are out of IEC 61883-1: - SID (source node id): always 0x0d - DBS (data block size): always 0x04 - DBC (data block counter): always 0x00 - EOH (End of header): always 0x00 Below is an actual sample of transferred packets. quads CIP1 CIP2 520 0x0D040400 0x22FFFFFF 8 0x0D040400 0x22FFFFFF 520 0x0D040400 0x22FFFFFF 520 0x0D040400 0x22FFFFFF 8 0x0D040400 0x22FFFFFF Status of clock is configured by write transactions to 0x'ffff'f000'0b14, as well as version 2, while meanings of fields are different from the former protocols. Modes of optical interfaces are configured by write transactions to 0x'ffff'f000'0c94. Drivers can register its address to receive heatbeat transactions from the unit. 0x'ffff'f000'0b0c is for the higher part and 0x'ffff'f000'0b10 is for the lower part. Nevertheless, this feature is not useless for this driver and this commit omits it. Each data block consists of two parts in a point of the number of included data chunks. In both of 'fixed' and 'differed' parts, the number of included data blocks are a multiple of 4, thus depending on models there's some empty data chunks. For example, 828mk3 includes one pair of empty data chunks in its fixed part. When optical interface is configured to S/PDIF, 828mk3 includes one pair of empty data chunks in its differed part. To reduce consumption of CPU cycles with additional conditions/loops, this commit just exposes these empty chunks to user space as PCM channels. Additionally, 828mk3 has a non-negligible overhead to change its sampling transfer frequency. When softwares send asynchronous transaction to perform it, LED on the unit starts to blink. In a worst case, it continues blink during several seconds; e.g. 10 seconds. When stopping blinking, the unit seems to be prepared for the requested sampling transfer frequency. To wait for the preparation, this commit forces the driver to call task scheduler and applications sleeps for 4 seconds.
