In IEC 61883-6, it's called as 'event' what has presentation time represented by timestamp in CIP header. Although the ratio of the number of event against the number of data block is different depending on event data type represented by the specific field in CIP header, it's just one in the most cases supported by ALSA IEC 61883-1/6 engine. In 1394 OHCI specification, applications can schedule hardware IRQ by configuring descriptor with IRQ flag for packet against each isochronous cycle. For future commit, I use the hardware IRQ for isoc IT context to acknowledge the elapse of PCM period for both playback/capture directions on AMDTP streams in the same domain. This commit is a preparation for the above idea. This commit adds a member into AMDTP domain structure to record the number of PCM frames.
