Message

Looks like this is going to be the final respin before this support
finally lands.
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.
