Cover letter [PATCH 0/4] IOMMU group cleanup
Quoted 10 lines · Robin Murphy

Hi all,

Prompted by some discussion around the questionable usefulness of iommu_present() for SoC topologies, I took a look at what was left to finish off the intention of making groups mandatory. Turns out it wasn't much, so here it is. As well as the general rationalisation aspect, between this and the probe-deferral changes in 4.12, we should now be able to rely on the presence of a group unambiguously indicating whether a given device is associated with an IOMMU or not.

Quoted 7 lines

Robin.

Robin Murphy (4):
iommu/msm: Add iommu_group support iommu/tegra-smmu: Add iommu_group support iommu/tegra-gart: Add iommu_group support
iommu: Finish making iommu_group support mandatory

Applied, thanks Robin.
