[alsa-devel] [PATCH 00/18] ALSA: firewire-motu: new driver for MOTU FireWire series

[Takashi Sakamoto]

Hi,

This patchset updates my previous RFCv2, and go for ALSA upstream.
http://mailman.alsa-project.org/pipermail/alsa-devel/2017-January/117211.html

This patchset newly adds a driver into ALSA firewire stack, to support for
some models in MOTU FireWire series:
 - 828mk2
 - 828mk3 (FireWire only)
 - 828mk3 (Hybrid)

The driver supports playbacking/capturing PCM frames and MIDI messages for any
sampling transfer frequencies, with current ALSA IEC 61883-1/6 packet streaming
engine.

Unfortunately, units on MOTU FireWire series have many quirks against
IEC 61883-1/6. This brings much commits and descriptions on this patchset.
Sorry for reviewers but I'm glad to get your assist for this patchset.

As I note in 8th commit, at sampling transfer frequency based on 44.1kHz, the
driver handles the units with choppy noises every few seconds. This is an issue
which is not resolved yet.

Changes from RFCv2:
 - drop trial support for 828. If you have interests in development, please
   refer to one commit of my previous RFC. It describes v1 protocol.
  - http://mailman.alsa-project.org/pipermail/alsa-devel/2017-January/117226.html
 - improve commit messages.
