Re: [alsa-devel] [PATCH] ASoC: simple-card: Don't create separate link when platform is present

10 Dec 2019

      Hi
...
In normal sound case all DAIs are detected as CPU-Codec.
simple_dai_link_of supports the presence of a platform but it counts
it as a CPU DAI resulting in the creation of an extra link.
Adding a platform property to a link description like:
simple-audio-card,dai-link {
   cpu {
   	sound-dai = <&sai1>;
   };
   plat {
   	sound-dai = <&dsp>;
   };
   codec {
   	sound-dai = <&wm8960>;
   }
will result in the creation of two links:

sai1 <-> wm8960
dsp  <-> wm8960

which is obviously not what we want. We just want one single link
with:

sai1 <-> wm8960 (and platform set to dsp).
