Detailed Description

struct soundwire_dpn - Configuration properties for SoundWire DPn Data Ports.

@port_max_wordlength: Maximum number of bits in a Payload Channel Sample. (1-64) @port_min_wordlength: Minimum number of bits in a Payload Channel Sample. (1-64) @port_wordlength_configs_count: Number of entries in port_wordlength_configs. @port_wordlength_configs: One entry for each supported wordlength. Used if only specific wordlength values are allowed. @data_port_type: Type of data port from &enum soundwire_data_port_type. @max_grouping_supported: 0-based maximum number of samples that can be grouped for FULL_DATA_PORT. The SIMPLIFIED_DATA_PORT and REDUCED_DATA_PORT require 4 samples in a group. @simplified_channelprepare_sm: true if the channel prepare sequence is not required, and the Port Ready interrupt is not supported. @port_channelprepare_timeout: Port-specific timeout value in milliseconds. @imp_def_dpn_interrupts_supported: Bitmap for support of implementation-defined interrupts. @min_channel_number: Minimum channel number supported. @max_channel_number: Maximum channel number supported. @channel_number_list_count: Number of entries in channel_number_list. @channel_number_list: One entry for each available channel number. Used if only specific channels are available. @channel_combination_list_count: Number of entries in channel_combination_list. @channel_combination_list: One bitmap entry for each valid channel combination. @modes_supported: Bitmap identifying the types of modes supported by the device. @max_async_buffer: Number of samples that this port can buffer in asynchronous modes. Only required if the slave implements buffer larger than required. @block_packing_mode: true if BlockPackingMode may be configured as BlockPerPort or BlocKPerChannel. false if BlockPackingMode must be BlockPerPort. @port_encoding_type: Bitmap describing the types of Payload Channel Sample encoding schemes implemented by this port. @port_audio_mode_count: Number of entries in audio_mode_list. @port_audio_mode_list: One entry for each supported audio mode id.
