[alsa-devel] [PATCH 0/9] ALSA: fireface: add support for Fireface UCX

[Takashi Sakamoto]

Hi,

In 2012, RME GmbH shipped Fireface UFX. This model is one of latter
models of Fireface series and support both of IEEE 1394 bus and USB.
Furthermore, it supports two types of remote control unit (Basic
Remote and Advanced Remote Control) with by 9pin mini-din connector.

This patchset adds support for this model, as a part of devices
by ALSA firewire stack (therefore it's not a device of USB). At
present, maintain of isochronous communication and synchronization
status are cleared but asynchronous communication for MIDI messages
are not yet, therefore this commit adds support for isochronous
communication for PCM frames.

This work is based on my packet analysis from rent device for a short
term (2 weeks). I'm happy to get your responses till next weekend.
Driver code in a remote branch is available for backport till Linux
kernel v4.17 or later for your test.
