Hi Sameer
Thank you for the patch

> newly exposed members.
re-use simple/audio-graph driver is nice idea.
My planning next new audio-graph2 can renuse it.

I have opinions about these.
About dpcm_selectable, indeed current audio-graph is using it as "uintptr_t",
but as you know, it checks whether it was non-NULL or not only.
This means we can use it as bit-field.
BTW, do we need to have dpcm_selectable at priv ?
One note is that, -scu- user is only me (locally),
and it will be removed when audio-graph2 was created.
(My plan is keep code for you, but remove compatible)
About *data, I think we can avoid *data
if driver side priv includes asoc_simple_priv ?
struct my_priv {
struct asoc_simple_priv *simple;
...
};
#define simple_to_priv(_simple) container_of((_simple), struct my_priv, simple)
Thank you for your help !!
Best regards
