It seems marginally better to include "sc7180-lpass.h" to get this? I
don't really know the difference between the two but since unless
we're planning to delete the sc7180 version it seems like you might as
well include that one?
Yes, I agree.
Recently, all Quallcomm variant headers are combined and created
"qcom,lpass.h".
"sc7180-lpass.h" still includes "qcom,lpass.h". So I will change and
repost the patch.
Here is the reference commit:

I'm an audio noob but isn't "MI2S_PRIMARY" something to be used with
"lpass_cpu", not with "alc5682" ?
I have no idea what the IDs correspond to on "alc5682". Are you sure
we even need an extra ID there? The "alc5682" bindings upstream don't
talk anything about dai-cells, but maybe they're just wrong...
Yes. I will change and re-post.
Actually, without dai-cells getting compilation issues. So I think it's
necessary here.
