+/* 4 ports */ +static struct sdw_dpn_prop wsa_sink_dpn_prop[WSA881X_MAX_SWR_PORTS] = { + { + /* DAC */ + .num = 1, + .type = SDW_DPN_SIMPLE,IIRC we added the REDUCED type in SoundWire 1.1 to cover the PDM case with channel packing (or was it grouping) used by Qualcomm. I am not sure the SIMPLE type works?grouping I guess.This is a simplified data port as there is no DPn_OffsetCtrl2 register implemented.
ok, for the REDUCED type it's required to have BlockPackingMode and OffsetCtrl2, so it does not apply here. Thanks for confirming.
