[alsa-devel] [PATCH 00/19][RFC v2] ALSA: firewire-motu: new driver for MOTU FireWire series

[Takashi Sakamoto]

Hi,

This patchset updates a part of my previous RFC, just for MOTU FireWire series.

[RFC][PATCH 00/37] ALSA: firewire: support AMDTP variants
http://mailman.alsa-project.org/pipermail/alsa-devel/2015-July/094789.html

This patchset adds support for a part of MOTU FireWire series with their
functionality of packet streaming. Below models are newly supported:
 - 828
 - 828mk2
 - 828mk3 (FireWire/Hybrid)

However, this module cannot handle 828 correctly to generate sound. The reason
is not clear yet. On the other hand, 828mk2 and 828mk3 can be handled most
properly via ALSA PCM/MIDI/HwDep interfaces.

Currently, I have a plan to post this patchset to merge into Linux 4.12.
Corresponding merge window will be estimated to open this April. If you're
willing to test this module, please report the result till then.

For testers, I prepared for backport modules in my repository. Please follow
instructions in README.

As user land tools, I added some stuffs to libhinawa and hinawa-utils. Please
refer to 'topic/motu' branch of these repositories. You can use
'hinawa-motu-common-cui' to configure some streaming-related features of the
above units:
