Hi Mark
If it is difficult to keep compatibility between current "simple" and simplified card, can we create above new sound cards series ? Some of these functions are already created as common code (but no one is using it ?) new sound cards series can reuse it.
I'm still seeing complexity here from the fact that we have to work out what combinations of features to support - if we're splitting things out then at some point we are going to have to have split code paths. It's possible I'm just not seeing the advantages here and that the code will make it clear what the benefits are but it doesn't feel like it's the way forwards right now.
Hmm... OK I see Let's skip to simplify simple-card.
But, I need sound card which supports sampling-rate-convert via DPCM, and I can't use simple-card for it, right ? So, I need to create new sound card anyway. I need guideline about it. Can I create it in sound/soc/generic, or should I create it in /sound/soc/sh/rcar ? "rate-controllable-audio-card" What do you think about this name ?
