The audio DSP is, in fact, contained within the audio subsystem. The representation of that relationship in the DT, I believe, would be a subnode. OTOH, if there is a strong sentiment towards using a phandle, that would be fine with me.
Just depends on how we communicate with the DSP. If its mostly via MMIO access than a sub node makes sense. If its via some other RPC/communication mechanism than possibly a phandle. Trying to understand a bit more to than see what I’d recommend.
It should be a phandle, while these things are all part of the same logical function in the CPU they're separate IPs and there may be many DAIs.
