Subject[PATCH v3 0/6] Add support for Qualcomm's legacy IOMMU v2
Date
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 v3:
- Removed useless FSRRESTORE reset and definition as pointed
out in Robin Murphy's review
- Fixed qcom,iommu.txt changes: squashed MSM8976 compatible
string addition with msm-iommu-v2 generics addition

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 (6):
dt-bindings: iommu: qcom,iommu: Document qcom,ctx-num property
iommu/qcom: Use the asid read from device-tree if specified
iommu/qcom: Properly reset the IOMMU context
iommu/qcom: Index contexts by asid number to allow asid 0
dt-bindings: iommu: qcom,iommu: Document QSMMUv2 and MSM8976
compatibles
iommu/qcom: Add support for QSMMUv2 and QSMMU-500 secured contexts
