Please use 'iommu/exynos:' as prefix for the iommu patches and start
the remaining subject with a capital letter, like this:
iommu/exynos: Don't read version register on every tlb operation
Okay, I will post an updated version soon

What is the plan for merging this, should it go through the iommu tree
or some other path?
I would prefer to split those patches into 3 trees and merge as follows:
- DTS changes and power domain changes via Samsung tree to avoid
conflicts with
other DTS patches
- all exynos-iommu patches and dma-mapping/reserved iommu region via
IOMMU tree,
- all Exynos DRM patches via DRM/Exynos tree.
There are no build cross-subsystem dependencies and IOMMU on Exynos is
already
nonfunctional (and disabled in defconfig) till now, so merging patches
in parts
doesn't break anything.
Best regards
