These are the patches from the from the prior series without the "fwspec
polishing":
https://lore.kernel.org/r/0-v2-36a0088ecaa7+22c6e-iommu_fwspec_jgg@nvidia.com
Does a few things to prepare for the next:
- Clean up the call chains around dma_configure so the iommu_ops isn't being
exposed.
- Add additional lockdep annotations now that we can.
- Fix some missed places that need to call tegra_dev_iommu_get_stream_id()
Based on Joerg's for-next with Robin's bus changes.
Robin's dma_base/size cleanup squashes the first patch, but we can't do
the ops removal in the other parts without it, so let's keep it
unsquashed.
v2:
- Remove comments and bracket around tegra_dev_iommu_get_stream_id()
in gp10b.c
- Remove WARN_ON() in tegra186_mc_client_sid_override(), just return 0
- Push the locking change to a later series
- Drop the COMPILE_TEST improvement, not important enough to argue.
v1: https://lore.kernel.org/r/0-v1-720585788a7d+811b-iommu_fwspec_p1_jgg@nvidia.com
Jason Gunthorpe (7):
iommu: Remove struct iommu_ops *iommu from arch_setup_dma_ops()
iommmu/of: Do not return struct iommu_ops from of_iommu_configure()
iommu/of: Use -ENODEV consistently in of_iommu_configure()
iommu: Mark dev_iommu_get() with lockdep
iommu: Mark dev_iommu_priv_set() with a lockdep
acpi: Do not return struct iommu_ops from acpi_iommu_configure_id()
iommu/tegra: Use tegra_dev_iommu_get_stream_id() in the remaining
places
