This patchset updates my previous RFC, excluding control/status message for TASCAM FireWire series and a MOTU driver,
[alsa-devel] [RFC][PATCH 00/37] ALSA: firewire: support AMDTP variants http://mailman.alsa-project.org/pipermail/alsa-devel/2015-July/094789.html
Unfortunately, I've got no dedicated testers to this patchset. While, the supported models have little time to live. I think it's time to merge them.
This patchset supports playbacking/capturing PCM samples/MIDI messages. Model specific functionalities such as MIDI mapping to physical controls should be done in userspace, with propper asynchronous transactions.
I hope users to remind that my work is done by reasoning and assuming with a result of investigating packets on IEEE 1394 bus. There's no published specification, thus these drivers cannot fully satisfies users' expectation which comes from Windows or OS X.
Changes: * Fix minor bugs, mainly for asynchronous transaction helper for MIDI port. * Regain PCM hardware constraint (I missed it). * Fix TASCAM quirk for MIDI transactions, as much as possible.
Rest of work (but may not be done in this developing period): * Handling control/status messages for TASCAM driver. * Supporting MIDI exclusive message for outgoing packets. * Researching a reason to de-synchronize for Digi00x family. * Improving MIDI throttle for asynchronous transaction helper
