ALSA: firewire-motu: add support for MOTU 896HD
Mark of the Unicorn (MOTU) shipped 896HD 2003 as one of models in second generation of its FireWire series, and already discontinued it. The model consists of below ICs: * Texas Instruments TSB41AB2 * Phillips Semiconductors PDI1394L40 * Altera cyclone EP1C3 * Texas Instruments TMS320VC5402 It supports sampling transmission frequency up to 192.0 kHz. The packet format differs depending on both of sampling transfer frequency and enabling ADAT channels. The model doesn't support MIDI message transmission. This commit adds support for it. $ python3 crpp < /sys/bus/firewire/devices/fw1/config_rom ROM header and bus information block ----------------------------------------------------------------- 400 04101b66 bus_info_length 4, crc_length 16, crc 7014 404 31333934 bus_name "1394" 408 20001000 irmc 0, cmc 0, isc 1, bmc 0, cyc_clk_acc 0, max_rec 1 (4) 40c 0001f200 company_id 0001f2 | 410 0001dbce device_id 000001dbce | EUI-64 0001f2000001dbce root directory ----------------------------------------------------------------- 414 0004c65c directory_length 4, crc 50780 418 030001f2 vendor 41c 0c0083c0 node capabilities per IEEE 1394 420 8d000006 --> eui-64 leaf at 438 424 d1000001 --> unit directory at 428 unit directory at 428 ----------------------------------------------------------------- 428 0003dcc1 directory_length 3, crc 56513 42c 120001f2 specifier id 430 13000005 version 434 17102800 model eui-64 leaf at 438 ----------------------------------------------------------------- 438 000264f2 leaf_length 2, crc 25842 43c 0001f200 company_id 0001f2 | 440 0001dbce device_id 000001dbce | EUI-64 0001f2000001dbce Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Link: https://lore.kernel.org/r/20210823085741.33864-1-o-takashi@sakamocchi.jp Signed-off-by: Takashi Iwai <tiwai@suse.de>
