2017-12-19soundwire: Add MIPI DisCo property helpersVinod Koul1-1/+22
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 <sanyog.r.kale@intel.com> Reviewed-by: Philippe Ombredanne <pombredanne@nexb.com> Acked-By: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com> Reviewed-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Vinod Koul <vinod.koul@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
