For a capture stream, it creates the following routes: Cpu_dai widget -> dai_link widget -> codec_dai widget

And for a playback stream: Codec_dai widget -> dai_link widget -> cpu_dai widget

Remember that for a CODEC<->CODEC link both devices will be CODECs so their widgets have the opposite sense as everything is named in a CPU centric fashion. The important thing is that we link playback to capture and capture to playback.
