This patch expand route setting by using DAI name.
You can select "ak4642-hifi" side "Playback" by below.

DT
	simple-audio-card,routing =

non DT
	struct snd_soc_dapm_route route[] = {

	}

If we're already specifying the DAI links for the (D)PCM code it seems
like we shouldn't also have to put DAPM routes for them in DT as well.

Yes, and I think we shouldn't use anything except for datahsheet pin names 
in the devicetree routing, because otherwise we are leaking driver 
implementation details.
