Currently, in the SoundWire subsystem, the concept of stream is limited to a Master and one or more Slaves(Codecs). This series aims to add support for multiple Master(s) sharing the same reference clock and synchronized in the hardware. This patch series adds: - Helpers to lock bus instances part of the stream - Boiler plate conversion of code to support a list of Master runtime - Support multi link bank switch to support synchronization between multiple masters - Add Intel platform ops for pre/post bank switch Sanyog Kale (2): Documentation: soundwire: Add documentation for Multi link soundwire: Add support to lock across bus instances Shreyas NC (3): soundwire: Initialize completion for defer messages soundwire: Add support for multilink bank switch soundwire: intel: Add pre/post bank switch ops Vinod Koul (1): soundwire: Handle multiple master instances in a stream Documentation/driver-api/soundwire/stream.rst | 30 +- drivers/soundwire/bus.c | 1 + drivers/soundwire/bus.h | 4 + drivers/soundwire/intel.c | 54 ++++ drivers/soundwire/stream.c | 429 ++++++++++++++++++-------- include/linux/soundwire/sdw.h | 6 +- 6 files changed, 390 insertions(+), 134 deletions(-) -- 2.7.4 _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
