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.

It came from snd_soc_of_parse_audio_routing()
Do you mean this function itself is not good ?

That's intended to be routing analogue pins to each other, not for DAI
links in DPCM - for DAI links we should be getting this information from
elsewhere.

While I agree with the sentiment for this when it comes to DAIs we
probably want to use the name the interfaces get in the documentation
rather than pin names since they involve multiple pins working together.

Sorry, but what does your "interfaces get in the documentation" mean ?

If the documentation refers to the interface as for example "I2S0" then
the DT should refer to it as I2S0 too.
