Hi all,
Since we'd like to get this polished up and merged and Leizhen has other commitments, here's v7 of the previous series[1] wherein I address all my own feedback :) This is a quick tweak of the v6 I sent yesterday since I figured out slightly too late a much neater way of setting the attribute at the appropriate time.
The principal change is that I've inverted things slightly such that it's now a generic domain attribute controlled by iommu-dma given the necessary support from individual IOMMU drivers. That way we can easily enable other drivers straight away, as I've done for SMMUv2 here (which also allowed me to give it a quick test with MMU-401s on a Juno board). Otherwise it's really just cosmetic cleanup and rebasing onto Will's pending SMMU queue.
Robin.
