ALSA: fireface: add support for Fireface 400
Fireface 400 is a second model of RME Fireface series, released in 2006. This commit adds support for this model. This model supports 8 analog channels, 2 S/PDIF channels and 8 ADAT channels in both of tx/rx packet. The number of ADAT channels differs depending on each mode of sampling transmission frequency. $ python2 linux-firewire-utils/src/crpp < /sys/bus/firewire/devices/fw1/config_rom ROM header and bus information block ----------------------------------------------------------------- 400 04107768 bus_info_length 4, crc_length 16, crc 30568 (should be 61311) 404 31333934 bus_name "1394" 408 20009002 irmc 0, cmc 0, isc 1, bmc 0, cyc_clk_acc 0, max_rec 9 (1024) 40c 000a3501 company_id 000a35 | 410 1bd0862a device_id 011bd0862a | EUI-64 000a35011bd0862a root directory ----------------------------------------------------------------- 414 000485ec directory_length 4, crc 34284 418 03000a35 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 000314c4 directory_length 3, crc 5316 42c 12000a35 specifier id 430 13000002 version 434 17101800 model eui-64 leaf at 438 ----------------------------------------------------------------- 438 000261a8 leaf_length 2, crc 25000 43c 000a3501 company_id 000a35 | 440 1bd0862a device_id 011bd0862a | EUI-64 000a35011bd0862a Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>
