Subject: [RESEND PATCH 0/4] Add support for SMMU ECMDQ

Resending the patches by Zhen Lei <thunder.leizhen@...wei.com> that add
support for SMMU's ECMDQ feature.

I have tested these patches on Marvell SoC that has the ECMDQ feature.

Zhen Lei (4):
  iommu/arm-smmu-v3: Add support for ECMDQ register mode
  iommu/arm-smmu-v3: Ensure that a set of associated commands are
    inserted in the same ECMDQ
  iommu/arm-smmu-v3: Add arm_smmu_ecmdq_issue_cmdlist() for non-shared
    ECMDQ
  iommu/arm-smmu-v3: Add support for less than one ECMDQ per core
