[alsa-devel] [PATCH 00/14] ALSA: Dice enhancement

[Takashi Sakamoto]

This 14 patchset is to enable ALSA Dice driver to handle more models with
some functionalities:
 - up to 192.0 kHz
 - PCM capture
 - MIDI playback/capture
 - Duplex streams with synchronization (with snd-firewire-lib)

This driver doesn't support:
 - Synchronization between multiple devices on the same bus
   For this purpose, please join in user-space driver project (FFADO)
 - Any control functionality for internal DSP
   For this purpose, please use ffado-dbus-server/ffado-mixer,
   or write your own application

Remarks:
 - When this driver is loaded, user-space driver fails to register
   notification address, thus cannot handle device for streaming. See:
http://mailman.alsa-project.org/pipermail/alsa-devel/2014-September/081731.html

Updates from my previous RFC:
http://mailman.alsa-project.org/pipermail/alsa-devel/2014-September/081673.html
 - Improve bus reset handling, especially for registering notification address
   At bus reset, Dice devices initialize a register for notification address,
   then drivers need to register the address again.
   Just after powering on, devices generates any bus reset, then drivers often
   fail to detect stream formation because this operation requires to change
   sampling rate.
   My improvement is retries to register notification address when notification
   wait is timed out.
 - Remove experimental state
 - Fix minor bugs
