Detailed Description

struct soundwire_audio_mode - Properties for each supported Audio Mode.

@sdw_name: SoundWire device name for this audio mode device instance. @max_bus_frequency: Maximum bus frequency of this mode in Hz. @min_bus_frequency: Minimum bus frequency of this mode in Hz. @bus_frequency_configs_count: Number of entries in bus_frequency_configs. @bus_frequency_configs: One entry for each supported bus frequency, if not all values in min to max range are valid. @max_sampling_frequency: Maximum sampling frequency of this mode in Hz. @min_sampling_frequency: Minimum sampling frequency of this mode in Hz. @sampling_frequency_configs_count: Number of entries in sampling_frequency_configs. @sampling_frequency_configs: One entry for each supported sampling frequency, if not all values in min to max range are valid. @prepare_channel_behavior: Dependencies between Channel Prepare and bus clock. @glitchless_transitions: Bitmap describing possible glitchless transitions from this audio mode to another audio mode. Not used for only one mode.
