Hi Laurent
What tree is the patch based on ? It doesn't apply on Takashi's latest master branch. I need a bit of context to review it.
(snip)
I've tried to understand the driver and couldn't even find out which DMA controller was used :-/ I suspect it's the audio peri-peri DMAC, but I haven't been able to confirm that from the source code. If the assumption is true the patch looks OK to me, but if you need a formal Acked-by then I'll need you to guide me through the driver I'm afraid.
Ahh I'm sorry about this confusion. It uses audio peri-peri DMAC, and, your rcar-dmac (as audio DMAC) The platform side is not upstreamed yet. (Because it depends on rcar-dmac)
But, I posted RFC audio DMAC support patches which was based on Ben's DMAC before.

I can re-post this patch if all DMAC was ready
