It's not flexible. When a new hardware connection is adopted, user needs to update struct sof_conn_stream defined in machine driver which is used to specify the mapping relationship of normal BE and SOF BE. In the patch, mtk_sof_check_tplg_be_dai_link_fixup() is introduced for all normal BEs. In mtk_sof_late_probe, back up normal BE fixup if it exists and then overwrite be_hw_params_fixup by the new callback. There are two cases for FE and BE connection. case 1: SOF FE -> normal BE -> SOF_BE case 2: normal FE -> normal BE In the new fixup callback, it tries to find SOF_BE which connects to the same FE, and then reuses the fixup of SOF_BE. If no SOF_BE exists, it must be case 2, so rollback to the original fixup if it exists. As a result, the predefined relation is not needed anymore. Hardware connection can be controlled by the mixer control for AFE interconn. Then, DPCM finds the BE mapping at runtime.
