[PATCH v2 00/33] iommu: Move iommu_group setup to IOMMU core code
Hi,
here is the second version of this patch-set. The first version with
some more introductory text can be found here:
https://lore.kernel.org/lkml/20200407183742.4344-1-joro at 8bytes.org/
Changes v1->v2:
* Rebased to v5.7-rc1
* Re-wrote the arm-smmu changes as suggested by Robin Murphy
* Re-worked the Exynos patches to hopefully not break the
driver anymore
* Fixed a missing

[RFC PATCH 00/34] iommu: Move iommu_group setup to IOMMU core code
Hi,
here is a patch-set to remove all calls of iommu_group_get_for_dev() from
the IOMMU drivers and move the per-device group setup and default domain
allocation into the IOMMU core code.
This eliminates some ugly back and forth between IOMMU core code and the
IOMMU drivers, where the driver called iommu_group_get_for_dev() which itself
called back into the driver.

[PATCH 00/15 v2] iommu: Move iommu_fwspec out of 'struct device'
Hi,
here is a patch-set to rename iommu_param to dev_iommu and
establish it as a struct for generic per-device iommu-data.
Also move the iommu_fwspec pointer from struct device into
dev_iommu to have less iommu-related pointers in struct
device.
The bigger part of this patch-set moves the iommu_priv
pointer from struct iommu_fwspec to dev_iommu, making is
usable for iommu-drivers which do not
