Hi Joerg,
Please pull these Arm SMMU updates for 5.6. The branch is based on your
arm/smmu branch and includes a patch addressing the feedback from Greg
about setting the module 'owner' field in the 'iommu_ops'.
I've used a signed tag this time, so you can see the summary of the
changes listed in there. The big deal is that we're laying the groundwork
for PCIe PASID support in SMMUv3, and I expect to hook that up for PCIe
masters in 5.7 once we've exported the necessary symbols to do so.
Cheers,
Will

PCI/ATS: Add PASID stubs (2020-01-15 16:30:28 +0000)
----------------------------------------------------------------
Arm SMMU updates for 5.6
- Support for building, and {un,}loading the SMMU drivers as modules
- Minor cleanups
- SMMUv3:
* Non-critical fix to encoding of TLBI_NH_VA invalidation command
* Fix broken sanity check on size of MMIO resource during probe
* Support for Substream IDs which will soon be provided by PCI PASIDs
- io-pgtable:
* Finish off the TTBR1 preparation work partially merged last cycle
* Ensure correct memory attributes for non-cacheable mappings
- SMMU:
* Namespace public #defines to avoid collisions with arch/arm64/
* Avoid using valid SMR register when probing mask size
