Current ASoC is supporting snd_soc_dai_link_component for binding, it is more useful than current legacy style. Currently only codec is supporting it as multicodec (= codecs). CPU will support multi style in the future. We want to have it on Platform too in the future.
If all Codec/CPU/Platform are replaced into snd_soc_dai_link_component style, we can remove legacy complex style. This patch supports snd_soc_dai_link_component style for simple-card for codec.
[current] struct snd_soc_dai_link { ... *cpu_name; *cpu_of_node; *cpu_dai_name;
*codec_name; *codec_of_node; *codec_dai_name; *codecs; num_codecs;
*platform_name; *platform_of_node; ... }
[in the future] struct snd_soc_dai_link { ... *cpus num_cpus;
*codecs; num_codecs;
*platform; ... }
