In the existing SoundWire code, Master Devices are not explicitly represented - only SoundWire Slave Devices are exposed (the use of capital letters follows the SoundWire specification conventions). With the existing code, the bus is handled without using a proper device, and bus->dev typically points to a platform device. The right thing to do as discussed in multiple reviews is use a device for each bus. The sdw_master_device addition is done with minimal internal plumbing and not exposed externally. The existing API based on sdw_bus_master_add() and sdw_bus_master_delete() will deal with the sdw_master_device life cycle, which minimizes changes to existing drivers. Note that the Intel code will be modified in follow-up patches (no impact on any platform since the connection with ASoC is not supported upstream so far).
