Re: [alsa-devel] [PATCH 8/8] ASoC: add snd-soc-dummy DT support

Hi Lars

Thank you for your feedback

quoted

This patch adds snd-soc-dummy DT binding support.

The devicetree describes the hardware, the snd-soc-dummy is a software only 
thing and should not be found in the devicetree.

Hmm... indeed
OK. I will re-consider about this

quoted

FE CPU   (rsnd):   "DAI0 Playback"
    Codec (dummy):  "Playback"

BE CPU   (dummy):  "Playback"
    Codec (ak4642): "Playback"

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.

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...

Best regards
