I suspect it's the latter; using the DMA API would mean updating all the
existing DMA drivers.

For audio use we'd probably also want to extend the DMA API to support
circular operation which I don't think it did last time I looked at it,
but that was when it was very shiny and new.  Ideally we'd be able to
have an ASoC DMA engine API client which would work over multiple
platforms which would be very nice.
