Robin and I were talking about CCA and DMA here:

https://lore.kernel.org/r/6c5fb9f0-c608-4e19-8c60-5d8cef3efbdf@arm.com

What do you think about pulling some of this out and trying to
independently push a series getting the DMA API layers ready for
device assignment?

I think there will be some discussion on these points, it would be
good to get started.
