[PATCH 0/6] ALSA: fireface: add support for Fireface 802 and UFX

[Takashi Sakamoto <o-takashi@sakamocchi.jp>]

Hi,

Fireface 802 was shipped by RME GmbH in 2014. 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 available
by ALSA firewire stack (therefore it's not a device of USB). Userspace
applications can transfer PCM frames and MIDI messages via ALSA PCM
and Rawmidi interfaces.

Fireface UFX is also supported since its internal design is almost the
same as Fireface 802 in a point of packet communication. The support is
untested and the status is 'request for test'.

As well as the other models of RME Fireface series, audio output
includes periodical hissing noise. This is not solved yet.

Furthermore, capture of MIDI messages requires assist of userspace
application. For the detail, please read comment in
'sound/firewire/fireface/ff-protocol-latter.c'.
