Cover letter [PATCH v3 0/5] iommu/arm-smmu: add support for non-pci devices
Quoted 9 lines · Zhen Lei

Changelog:
v2 -> v3:
1. add support for pci device hotplug, which missed in patch v2.
2. only support #iommu-cells = <1>, add corresponding description in arm,smmu-v3.txt.
3. add function find_smmu_by_device which extracted from find_smmu_by_node, to resolve the problem mentioned by Robin Murphy in [PATCH v2 7/9]. Additionally:
+ platform_set_drvdata(pdev, smmu); //Patch v2
+ dev->archdata.iommu = smmu; //Patch v3, dev = &pdev->dev

I didn't give any Reviewed-by tags, much less to revised patches that I've not even looked at yet; please see section 13 of Documentation/SubmittingPatches for what the Reviewed-by tag means.

Robin.
