Hi,
This patchset updates my previous RFCv3, and go for ALSA upstream.
[alsa-devel] [RFC v3][PATCH 00/13] ALSA: fireface: new driver for RME Fireface series http://mailman.alsa-project.org/pipermail/alsa-devel/2017-February/117811.ht...
This patchset newly adds a driver into ALSA firewire stack, to support for Fireface 400 in RME FireWire series.
Unfortunately, units on this series are completely against IEC 61883-1/6. This brings much commits and descriptions into this patchset. I'd ask you to review much amount of codes, as well as MOTU FireWire series, to finish my work for AMDTP variants[0].
As I noted to my former patchset, units of the series have unique feature; resampling between packet/data block processing layer and sample processing layer. This patchset relies on this layer, in short the driver doesn't handle sampling clock frequency, just handle sampling transmission frequency and expects units to generates audio from resampled data. Users should use proper application to configure sampling clock frequency when they want to match the frequency and sampling transmission frequency.
Changes from RFCv3:
- Add function pointer to AMDTP structure to reduce branching on packet processing.
- Improve commit description.
