[alsa-devel] [RFC v3][PATCH 00/13] ALSA: fireface: new driver for RME Fireface series

[Takashi Sakamoto]

Hi,

This patchset is a revised version of my former one:

[alsa-devel] [RFC v2][PATCH 00/11] ALSA: fireface: new driver for RME Fireface series
http://mailman.alsa-project.org/pipermail/alsa-devel/2015-December/102261.html

Since the end of 2015, ALSA firewire stack got many changes. This revision
adapt the former one to current stack. Furthermore, I add an abstraction layer
of Fireface protocol to help developers to add support for the rest of models.
(I'm unwilling to work further for this direction, because of its cost.)

Changes:
 * Rebase to current ALSA firewire stack and add optimization.
 * Rename local structure with shorter words.
 * Delegate a task to configure settings on write-only registers to user space
   applications.
 * Switch mode to fetch PCM frames from data blocks to sampling data processing
   layer voluntarily.
 * Revise comments with technical information from my analysis to Fireface 400
   packets.

The rebasing is actually done on my proposal of ALSA MOTU driver. Please apply
this patchset to it to prevent conflicts.
[alsa-devel] [PATCH 00/19][RFC v2] ALSA: firewire-motu: new driver for MOTU FireWire series
http://mailman.alsa-project.org/pipermail/alsa-devel/2017-January/117211.html

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.

Unfortunately, I did this work just with my notes and log dumps, thus without
any test device. I'm happy if you test this patchset with your Fireface 400.
For testers, I prepare for backport codes in my repository in github.com.
Please use 'topic/fireface' branch.

If you have any question, please reply to me even if it's trivial; e.g. typo
in comments, as long as its' technical issue.
