[alsa-devel] [PATCH 0/6] ALSA: fireface: support MIDI functionality of Fireface UCX

[Takashi Sakamoto]

Hi,

This patchset is a supplement of my previous one and to complete support
for Fireface UCX:
[alsa-devel] [PATCH 0/9] ALSA: fireface: add support for Fireface UCX
http://mailman.alsa-project.org/pipermail/alsa-devel/2019-January/144465.html

The mechanism to use MIDi functionality of Fireface UCX is different
from the other supported devices; Fireface 800 and Fireface 400. This
patchset extends abstraction layer of hardware specification and
communication protocol.

Unfortunately, a bitflag to decide lower part of address to transfer
asynchronous transaction for MIDI message is in option register which
has the other options. This driver expects userspace applications to
configure the option as expected. In detail please refer to third patch.

For testers, a remote branch is available to backport a series of
patches to Linux kernel v4.17 or later:
https://github.com/takaswie/snd-firewire-improve/tree/topic/ff-ucx-midi

A userspace tool to configure addressed register is available in another
remote branch for hinawa-utils:
https://github.com/takaswie/hinawa-utils/tree/topic/ff-ucx

As I noted in previous patchset, this work is based on my packet analysis
from rent device for a short term (2 weeks). I'm happy to get your
response till next weekend.

Regards
