Patch 1 is cleanup to support other SoCs to call into QCOM specific implementation. Patch 2 sets the default identity domain for DRM devices. Patch 3 implements def_domain_type callback for arm-smmu. Patch 4 sets the default identity domain for modem device. Patch 5-6 adds the iommus property for mss pil. This is based on Joerg's tree: - https://git.kernel.org/pub/scm/linux/kernel/git/joro/linux.git/log/?h=iommu-probe-device-v2 v4: * Updated commit msg for mss pil requesting direct mapping v3: * Use arm_smmu_master_cfg to get impl instead of long way as per Robin. * Use def_domain_type name for the callback in arm_smmu_imp as per Robin Jordan Crouse (1): iommu/arm-smmu: Allow client devices to select direct mapping Sai Prakash Ranjan (2): iommu: arm-smmu-impl: Convert to a generic reset implementation iommu/arm-smmu: Implement iommu_ops->def_domain_type call-back Sibi Sankar (3): iommu/arm-smmu-qcom: Request direct mapping for modem device dt-bindings: remoteproc: qcom: Add iommus property arm64: dts: qcom: sdm845-cheza: Add iommus property .../bindings/remoteproc/qcom,q6v5.txt | 3 ++ arch/arm64/boot/dts/qcom/sdm845-cheza.dtsi | 5 +++ drivers/iommu/arm-smmu-impl.c | 8 ++-- drivers/iommu/arm-smmu-qcom.c | 37 +++++++++++++++++-- drivers/iommu/arm-smmu.c | 12 ++++++ drivers/iommu/arm-smmu.h | 1 + 6 files changed, 60 insertions(+), 6 deletions(-)
