Sorry, Does this means under Documentation ?
Or driver ?

I see. will do in v3

I guess it can share format between codec/dai,
but it is difficult for inversion.
Because it is depends on its default clock polarity.
of course we can do
 simple-audio,platform,dai-bitlock-inversion
 simple-audio,platform,codec-bitlock-inversion
but it is same thing.
