ALSA: oxfw: perform sequence replay for media clock recovery
This commit takes ALSA oxfw driver to perform sequence replay for media clock recovery. Unfortunately, OXFW970 ASIC and its firmware has a quirk called jumbo payload which skips several isochronous cycles for packet transmission, thus the sequence replay is just adopted to OXFW971 ASIC. As well as Fireworks, OXFW ASICs also ignores presentation time against the way in IEC 61883-1/6. The sequence replay is tested with below models: * Tascam FireOne * Stanton Magnetics SCS.1m * Apogee Duet FireWire For below models, the sequence replay is tested to be disabled: * Griffin FireWave * Behringer F-Control Audio 202 * Loud Technology Tapco Link.FireWire 4x6 * Loud Technology Mackie Onyx Satellite Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Link: https://lore.kernel.org/r/20210531025103.17880-4-o-takashi@sakamocchi.jp Signed-off-by: Takashi Iwai <tiwai@suse.de>
