Hi Mark
Current ALSA SoC has CPU/Codec categorized DAIs.
But we want to have non-categorized DAIs in the future.
This was indicated by Lars-Peter before at ELCE.
But, we *can't* do it right now.
Because many drivers are considering CPU and Codec separately.
Currently, rtd has both CPU/Codec DAIs array.
rtd->cpu_dais = [][][][][][][][][]
rtd->codec_dais = [][][][][][][][][]
This patch merges these, like below.
It still can use rtd->cpu_dais, rtd->codec_dais.
Of course for_each_rtd_cpu/codec_dais() macro too.
So we can use/keep existing code/method same as before.
rtd->dais = [][][][][][][][][][][][][][][][][][]
^cpu_dais ^codec_dais
|--- num_cpus ---|--- num_codecs --|
rtd->cpu_dais = &rtd->dais[0];
rtd->codec_dais = &rtd->dais[dai_link->num_cpus];
There are some code which is doing something *only* for CPU or Codec.
This patch-set do nothing to such code.
Maybe it can be updated in the future, maybe not (can't).
I hope this patch-set can be 1st step for non-categorized DAIs.
But the main purpose so far is that replace the duplicate code
for borh CPU and Codec.
- for_each_rtd_cpu_dais() {
- ...
- }
- for_each_rtd_codec_dais() {
- ...
- }
+ for_each_rtd_dais() {
+ ...
+ }
