soundwire: intel: Add Intel init module

2017-12-19T10:32:35+00:00

The SoundWire Master is implemented as part of Audio controller in Intel platforms. Add a init module which creates SoundWire Master platform devices based on the links supported in the hardware.

soundwire: Add MIPI DisCo property helpers

2017-12-19T10:14:57+00:00

MIPI Discovery And Configuration (DisCo) Specification for SoundWire specifies properties to be implemented for SoundWire Masters and Slaves. The DisCo spec doesn't mandate these properties. However, SDW bus cannot work without knowing these values. The helper functions read the Master and Slave properties. Implementers of Master or Slave drivers can use any of the below three mechanisms: a) Use these APIs here as .read_prop() callback for Master and Slave b) Implement own methods and set those as .read_prop(), but invoke APIs in this file for generic read and override the values with platform specific data c) Implement ones own methods which do not use anything provided here Signed-off-by: Sanyog Kale Reviewed-by: Philippe Ombredanne Acked-By: Pierre-Louis Bossart Reviewed-by: Takashi Iwai Signed-off-by: Vinod Koul Signed-off-by: Greg Kroah-Hartman

soundwire: Add Master registration

2017-12-19T10:14:56+00:00

A Master adds a SoundWire bus instance which scans the firmware provided for device description. In this patch we scan ACPI namespaces and create SoundWire Slave devices based on ACPI description Signed-off-by: Sanyog Kale Reviewed-by: Philippe Ombredanne Acked-By: Pierre-Louis Bossart Reviewed-by: Takashi Iwai Acked-by: Greg Kroah-Hartman Signed-off-by: Vinod Koul Signed-off-by: Greg Kroah-Hartman

soundwire: Add SoundWire bus type

2017-12-19T10:14:56+00:00

This adds the base SoundWire bus type, bus and driver registration. along with changes to module device table for new SoundWire device type.
