Thanks a lot for updating this material: We really appreciate.
We will try to review this material together with Jean-Christophe and
colleagues @ Atmel. I hope that we will go forward with this collected
material in the near future.
Maybe DMA OF part will not be upstreamed as-is because of an ongoing
initiative to build a generic dmaengine OF support.

I know that Jean-Christophe has had difficulties to have feedback on
there parts...

This will certainly be squashed in previous path.

This one also: but it is good to have them separated at fist.

Is it fixup for a bug? Jean-Christophe, a though about this one?

Maybe documentation has to be folded in the patch that actually adds the
OF support.
