[PATCH v7 00/22] Generic DT bindings for PCI IOMMUs and ARM SMMU

[Robin Murphy]

Hi all,

To any more confusing fixups and crazily numbered extra patches, here's
a quick v7 with everything rebased into the right order. The significant
change this time is to implement iommu_fwspec properly from the start,
which ends up being far simpler and more robust than faffing about
introducing it somewhere 'less intrusive' to move toward core code later.

New branch in the logical place:

git://linux-arm.org/linux-rm iommu/generic-v7

Robin.
