2 SoundWire Subsystem Summary
5 SoundWire is a new interface ratified in 2015 by the MIPI Alliance.
6 SoundWire is used for transporting data typically related to audio
7 functions. SoundWire interface is optimized to integrate audio devices in
10 SoundWire is a 2-pin multi-drop interface with data and clock line. It
12 Broad level key features of SoundWire interface include:
15      commands over a single two-pin interface.
23  (4) Device status monitoring, including interrupt-style alerts to the Master.
25 The SoundWire protocol supports up to eleven Slave interfaces. All the

58 The MIPI SoundWire specification uses the term 'device' to refer to a Master
62 device managed by a specific driver. The Linux SoundWire subsystem provides
63 a framework to implement a SoundWire Slave driver with an API allowing
64 3rd-party vendors to enable implementation-defined functionality while

100 Following is the Bus API to register the SoundWire Bus:
