[RFC,0/9] iommy/arm-smmu-qcom: Rework Qualcomm SMMU bindings and implementation

Message

Dmitry Baryshkov Oct. 21, 2022, 4:55 p.m. UTC

The main goal of this patchset is to define a generic qcom,smmu-500
binding to be used by newer Qualcomm platforms instead of defining each
and every SoC line with no actual differences between the compats.

While preparing this change it was required to cleanup the existing
bindings and to rework the way the arm-smmu-qcom implementation handles
binding to IOMMU devices.

Dmitry Baryshkov (9):
  dt-bindings: arm-smmu: Add missing Qualcomm SMMU compatibles
  dt-bindings: arm-smmu: fix clocks/clock-names schema
  dt-bindings: arm-smmu: Add generic qcom,smmu-500 bindings
  iommu/arm-smmu-qcom: Move implementation data into match data
  iommu/arm-smmu-qcom: Move the qcom,adreno-smmu check into
    qcom_smmu_create
  iommu/arm-smmu-qcom: provide separate implementation for
    SDM845-smmu-500
  iommu/arm-smmu-qcom: Merge table from arm-smmu-qcom-debug into match
    data
  iommu/arm-smmu-qcom: Stop using mmu500 reset for v2 MMUs
  iommu/arm-smmu-qcom: Add generic qcom,smmu-500 match entry
