From: Kuninori Morimoto <kuninori.morimoto.gx at renesas.com>
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;
...
}
