[alsa-devel] [PATCH 0/6] soundwire: Add multi link support

[Shreyas NC]

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
