Changes since v2:
* Fixed build issues resulting from wrong patch
order, everything should be nicely bisectable now
* Introduced wrapper functions around
'struct iommu_device' members, to keep the struct
empty when !CONFIG_IOMMU_API
* Renamed the iommu-devices on Exynos as suggested
by Marek Szyprowski
Changes since v1:
* Rebased to v4.10-rc7
* Fixed build failures found by the
kbuild test robot
Hi,
the IOMMU core code already has two ways of representing
individual hardware IOMMUs. One is the sysfs code and the
other is the newer iommu_register_instance interface. These
two interfaces are special purpose and can be unified.
This unification is attempted in this patch-set. It
introduces an extensible 'struct iommu_device' which
represents a hardware IOMMU in the IOMMU core code.
For now the struct contains a pointer to the iommu_ops, which
is a step to get rid of the per-bus iommu_ops, and a pointer
to a firmware-node structure.
The patches have been tested on x86 hardware and an AMD Seattle
ARM64 system.
Please review, test and provide feedback!
Thanks a lot,
Joerg
