ASoC: rsnd: enable multi Component support for Audio Graph Card/Card2
+-- Basic Board ---------+
|+--------+ +------+|
|| CPU ch0| <--> |CodecA||
|| ch1| <-+ +------+|
|+--------+ | |
+-------------|----------+
+-- expansion board -----+
| | +------+|
| +->|CodecB||
| +------+|
+------------------------+
In above HW connection case, we intuitively think we want to handle these
as "2 Sound Cards".
card0,0: CPU-ch0 - CodecA
card1,0: CPU-ch1 - CodecB
But, we needed to handle it as "1 big Sound Card", because of
Component vs Card limitation.
card0,0: CPU-ch0 - CodecA
card0,1: CPU-ch1 - CodecB
This patch enables multi Component to handle multi Cards.
To support it, it needs
- Fill dai_args for each DAI on snd_soc_dai_driver
- Parse DT for each Component (Simple Card/Audio Graph Card)
Ex) Simple Card
rcar_sound {
...
/* Component0 */
rcar_sound,dai@0 {
...
};
/* Component1 */
rcar_sound,dai@1 {
...
};
};
Ex) Audio Graph Card/Card2
rcar_sound {
/* Component0 */
ports@0 {
...
};
/* Component1 */
ports@1 {
...
};
};
