Subject: [RFC PATCH v2 00/11] iommu/arm-smmu-qcom: Rework Qualcomm SMMU bindings and implementation
Date: Wed, 2 Nov 2022 21:44:09 +0300 [thread overview]
Message-ID: <20221102184420.534094-1-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 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
