[PATCH 0/6] ALSA: firewire: media clock recovery for syt-unaware devices

[Takashi Sakamoto]

Hi,

In a commit f9e5ecdfc2c2 ("ALSA: firewire-lib: add replay target to cache
sequence of packet"), I categorize devices supported by drivers in ALSA
firewire stack in terms of the way to deliver effective sampling
transfer frequency. This patchset is for the devices in group 1.

The devices in the group ignore presentation time to decide playback
timing, therefore drivers to handle them can ignore processing
presentation time expressed in syt field of CIP header. The sequence of
the number of data blocks per packet is important for media clock recovery.
With the patchset, the drivers are going to replay the sequence. For the
detail of sequence replay, please refer to a commit 39c2649c71d8 ("ALSA:
firewire-lib: replay sequence of incoming packets for outgoing packets").
