ALSA: firewire-motu: add support for MOTU UltraLite
UltraLite was shipped in 2005 by MOTU, and already discontinued. This model consists of below ICs: - Texus Instruments TSB41AB2 for physical layer of IEEE 1394 bus - Xilinx Spartan XC35S200 for link layer of IEEE 1394 bus, protocol layer and signal processing This commit adds support for this model. Like the other MOTU models, ALSA firewire MOTU driver fails to drive the device for stable sampling clock and generate noisy sound. $ python2 crpp < /sys/bus/firewire/devices/fw1/config_rom ROM header and bus information block ----------------------------------------------------------------- 400 04107574 bus_info_length 4, crc_length 16, crc 30068 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 0007b82d device_id 000007b82d | EUI-64 0001f2000007b82d 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 0003d80a directory_length 3, crc 55306 42c 120001f2 specifier id 430 1300000d version 434 17100800 model eui-64 leaf at 438 ----------------------------------------------------------------- 438 00024566 leaf_length 2, crc 17766 43c 0001f200 company_id 0001f2 | 440 0007b82d device_id 000007b82d | EUI-64 0001f2000007b82d Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Link: https://lore.kernel.org/r/20191030080644.1704-7-o-takashi@sakamocchi.jp Signed-off-by: Takashi Iwai <tiwai@suse.de>
