IOMMU/DT folks, any thoughts about this approach? The patches that are 
of interest outside of Host1x/TegraDRM specifics are patches 1, 2, 4, 
and 5.

FWIW it looks fairly innocuous to me. I don't understand host1x - 
neither hardware nor driver abstractions - well enough to meaningfully 
review it all (e.g. maybe it's deliberate that the bus .dma_configure 
method isn't used?), but the SMMU patch seems fine given the Kconfig 
solution to avoid module linkage problems.

Thanks Robin! Will, Joerg, is OK with you?

Mikko, I believe we are missing a dt-binding change to document the 
'memory-contexts' node which I assume you will add if everyone is OK 
with this?

Cheers
Jon
