Subject: [PATCH v1 00/10] iommu/arm-smmu-qcom: Rework Qualcomm SMMU bindings and implementation
Date: Mon, 14 Nov 2022 20:06:25 +0300	[thread overview]
Message-ID: <20221114170635.1406534-1-dmitry.baryshkov@linaro.org> (raw)

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.

Changes since RFC v2:
 - Dropped the dts patch, picked up by Bjorn
 - Fixed minor nits in commit messages and in-file comments (noted by
   Krzysztof and Richard Acayan)

Changes since RFC v1:
 - Added the dts patch fixing order of clocks in msm8996.dtsi
 - Fixed the DT bot errors
 - Added separate clause for Google Cheza devices

Dmitry Baryshkov (10):
  dt-bindings: arm-smmu: Add missing Qualcomm SMMU compatibles
  dt-bindings: arm-smmu: fix clocks/clock-names schema
  dt-bindings: arm-smmu: add special case for Google Cheza platform
  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
