The change isn't much from v17_resend series [1] besides taking Thor's change [2] for clocks. Changes since v17: - Addressing Will's comment to embed Thor's change [2] for pulling clocks information from device tree. This is done by squashing Thor's change [2] in v17's 1/5 patch [3]. - Another minor change is addition of runtime pm hooks to arm_smmu_iova_to_phys_hard(). Previous version of this patch series is @ [1]. Also refer to [4] for change logs for previous versions.
