I think there weren't any comments left for me to address and I've mostly been waiting for Joerg to pick it up. Joerg, can you take this through the iommu tree for 3.17? Will acked this, but perhaps you were waiting for an ACK from the device tree bindings maintainers? Will, perhaps you can get Pawel or Mark to look at this? Arnd, I'm sure if we had your Acked-by that would go a long way too.
