That's something we need to fix, but I don't think removing the stream names 
is the right way to do this. In a multi CODEC environment you'll quite 
likely end up with widgets of the same name. Ideally a route endpoint would 
be expressed by a tuple of DT node and pin name. But I don't think it is 
possible to mix integer and string elements in a property.

It's not.  Now that we have preprocessor support it's a lot easier to
just use numbers though - the legibility problems from just using raw
numbers in big tables don't apply so much any more.

Thank you for your advice.
"DT node and name" seems nice idea, but it works on DT case only ?
Anyway, I re-consider about this too.
It can be trial and error...

I think that for hardware which has fairly monolithic audio blocks using
DPCM it might be worth thinking about providing a way for the DT to look
like the DT for a simple I2S DAI with the driver for the IP in the SoC
filling in all the structure needed by DPCM.
