Hi Mark, again
These are [RFC] patches which adds new rule for modern style dai_link. Many sound are using CPU component as Platform component, and then it has below settings on legacy style dai_link
dai_link->platform_of_node = dai_link->cpu_of_node
But, this duplicated component will be just ignored because it is already selected when CPU component binding. We want to allow "no Platform" on modern style dai_link.
And, current legacy style dai_link allows no Platform settings, then, soc-core will select snd-soc-dummy platform for it automatically. In modern style, we need to have CPU/Codec/Platform as array/pointer style. Thus, this kind of "implicit" selection will be just un-understandable.
These 2 patches adds new rule for modern style, and have no effect to legacy style. But, I can't test for *all* board/situation. Thus, I added [RFC] for these.
And, I think these are no special effect on Codec<->Codec. But, need to check/test.
