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 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 (11): arm64: dts: qcom: msm8996: change order of SMMU clocks on this platform 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 .../devicetree/bindings/iommu/arm,smmu.yaml | 172 +++++++++++++++++- arch/arm64/boot/dts/qcom/msm8996.dtsi | 31 ++-- .../iommu/arm/arm-smmu/arm-smmu-qcom-debug.c | 91 --------- drivers/iommu/arm/arm-smmu/arm-smmu-qcom.c | 156 +++++++++++----- drivers/iommu/arm/arm-smmu/arm-smmu-qcom.h | 21 ++- 5 files changed, 307 insertions(+), 164 deletions(-)
