[GIT PULL] iommu/arm-smmu: Updates for 4.5

[Will Deacon]

Hi Joerg,

Please pull the following arm-smmu updates for 4.5. Highlights include:

  * Some fixes to get the driver working nicely on Broadcom hardware
  * A change to the io-pgtable API to indicate the unit in which to
    flush (all callers converted, with Ack from Laurent)
  * Use of devm_* for allocating/freeing the SMMUv3 buffers

I'll be disappearing after tomorrow, but I'll be back on 4 January.

Cheers,

Will
