Cheers,
This short series adds support for the adreno-smmu implementation of the arm-smmu driver and the device-tree bindings to turn on the implementation for the sm845 and sc7180 GPUs. These changes are the last ones needed to enable per-instance pagetables in the drm/msm driver. v19: Rebase to kernel/git/will/linux.git for-joerg/arm-smmu/updates to pick up system cache patches and devm_realloc() updates. Use a function hook to modify / write sctlr v18: No deltas in this patchset since the last go-around for 5.10 [1].
