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).
