2019-10-18ALSA: oxfw: share PCM buffer size for both directionTakashi Sakamoto1-2/+2
This commit allows ALSA oxfw driver to share PCM buffer size for both capture and playback PCM substream. When AMDTP domain starts for one of the PCM substream, buffer size of the PCM substream is stores to AMDTP domain structure. Some AMDTP streams have already run with the buffer size when another PCM substream starts, therefore the PCM substream has a constraint to its buffer size.

2019-10-17ALSA: oxfw: register the size of PCM period to AMDTP domainTakashi Sakamoto1-2/+2
This commit is a preparation to share the size of PCM period between PCM substreams on AMDTP streams in the same domain. At this time, the size of PCM period in PCM substream which starts AMDTP streams in the same domain is recorded.

https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus ASoC: Updates for v5.3 This is a very big update, mainly thanks to Morimoto-san's refactoring work and some fairly large new drivers. - Lots more work on moving towards a component based framework from Morimoto-san. - Support for force disconnecting muxes from Jerome Brunet. - New drivers for Cirrus Logic CS47L35, CS47L85 and CS47L90, Conexant CX2072X, Realtek RT1011 and RT1308.

2019-07-07ALSA: oxfw: fix wrong reference count for stream functionality at error path ↵Takashi Sakamoto1-0/+2
of rawmidi interface In IEC 61883-6, several types of sampling data can be multiplexed into payload of common isochronous packet (CIP). For typical audio and music units, PCM samples and MIDI messages are multiplexed into one packet streaming. ALSA oxfw driver allows applications of rawmidi interface to start packet streaming for transmission of MIDI messages. However at error path, the reference count of stream functionality is not operated correctly. This can brings a bug that packet streaming is not stopped when all referrers release the count. This commit fixes the bug.

2019-06-12ALSA: oxfw: configure packet format in pcm.hw_params callbackTakashi Sakamoto1-4/+10
This commit is a part of preparation to perform allocation/release of isochronous resources in pcm.hw_params/hw_free callbacks. At present, several operations are done in pcm.prepare callback. To reduce load of the callback, This commit splits out an operation to set packet format in pcm.hw_params callback.

2019-06-12ALSA: oxfw: rename helper functions for duplex streamsTakashi Sakamoto1-4/+4
In former commits, ALSA oxfw driver handles two isochronous contexts at the same time, except for some devices which supports one endpoint of isochronous packet stream. This commit renames some helper functions so that they handles duplex streams. Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2017-01-05ALSA: oxfw: enclose identifiers referred by single functionTakashi Sakamoto1-14/+12
Some identifiers are referred just by one functions. In this case, they can be put into the function definition. This brings two merits; readers can easily follow codes related to the identifiers, developers are free from name conflict. This commit moves such identifiers to each function definition.

2015-10-19ALSA: oxfw: calculating MIDI ports in stream discoverTakashi Sakamoto1-21/+3
Current OXFW driver calculates the number of MIDI ports just before adding ALSA MIDI ports. It's convenient for some devices with quirks to move these codes before handling quirks. This commit implements this idea. Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2015-09-29ALSA: firewire-lib: move MIDI trigger helper function to AM824 layerTakashi Sakamoto1-8/+8
In IEC 61883-6, MIDI messages are transferred in MIDI conformant data channel. Essentially, packet streaming layer is not responsible for MIDI functionality. This commit moves MIDI trigger helper function from the layer to AM824 layer. The rest of codes related to MIDI functionality will be moved in later commits.

2014-12-10ALSA: oxfw: Add support for capture/playback MIDI messagesTakashi Sakamoto1-0/+191
This commit adds MIDI functionality with an assumption of 'if the device has MIDI comformant data channels in its stream formation, the device has one MIDI port'. When no streams have already started, MIDI functionality starts stream with current sampling rate. When MIDI functionality has already starts some streams and PCM functionality is going to start streams at different sampling rate, this driver stops streams once and changes sampling rate, then restarts streams for both PCM/MIDI substreams.
