Besides my one comment on the last patch this series looks good to me. Do you plan to include it (with the fall-back) into your pull-request?

Yes, that would certainly be easiest for me, given the changes to the SMMU drivers. However, if you prefer it separately then I can do that too.

Cheers,

Will
