This series adds support for handling "v2" firmware's IOMMU, found on at least MSM8956 and MSM8976 (some other SoCs also need the same but I honestly don't remember which ones precisely). This is strictly required to get functional IOMMUs on these SoCs. I'm sorry for not performing a much needed schema conversion on qcom,iommu.txt, but I really didn't have time to do that :-( This series was tested on Sony Xperia X and X Compact (MSM8956): ADSP, LPASS, Venus, MSS, MDP and GPU are happy :-) Changes in v2: - Added back Marijn's notes (sorry man!) - Added ARM_SMMU_CB_FSRRESTORE definition - Changed context bank reset to properly set FSR and FSRRESTORE AngeloGioacchino Del Regno (8): dt-bindings: iommu: qcom,iommu: Document qcom,ctx-num property iommu/qcom: Use the asid read from device-tree if specified iommu/arm-smmu: Add definition for ARM_SMMU_CB_FSRRESTORE iommu/qcom: Properly reset the IOMMU context iommu/qcom: Index contexts by asid number to allow asid 0 dt-bindings: iommu: qcom,iommu: Document QSMMU v2 compatibles iommu/qcom: Add support for QSMMUv2 and QSMMU-500 secured contexts dt-bindings: iommu: qcom,iommu: Document MSM8976 compatible .../devicetree/bindings/iommu/qcom,iommu.txt | 11 ++- drivers/iommu/arm/arm-smmu/arm-smmu.h | 1 + drivers/iommu/arm/arm-smmu/qcom_iommu.c | 78 +++++++++++++++---- 3 files changed, 71 insertions(+), 19 deletions(-) -- 2.38.1
