charset="us-ascii" Content-Transfer-Encoding: 7bit Sender: "linux-arm-kernel" Errors-To: linux-arm-kernel-bounces+linux-arm-kernel=archiver.kernel.org@lists.infradead.org This patch mainly adds support for mt8192 Multimedia IOMMU and SMI. mt8192 also is MTK IOMMU gen2 which uses ARM Short-Descriptor translation table format. The M4U-SMI HW diagram is as below: EMI | M4U | ------------ SMI Common ------------ | +-------+------+------+----------------------+-------+ | | | | ...... | | | | | | | | larb0 larb1 larb2 larb4 ...... larb19 larb20 disp0 disp1 mdp vdec IPE IPE All the connections are HW fixed, SW can NOT adjust it. Comparing with the preview SoC, this patchset mainly adds two new functions: a) add iova 34 bits support. b) add multi domains support since several HW has the special iova region requirement. change note: v4: a) rebase on v5.10-rc1 b) Move the smi part to a independent patchset. c) Improve v7s code from Robin and Will. d) Add a mediatek iommu entry patch in MAINTAINERS. v3: https://lore.kernel.org/linux-iommu/20200930070647.10188-1-yong.wu@mediatek.com/ a) Fix DT schema issue commented from Rob. b) Fix a v7s issue. Use "_lvl" instead of "_l" in the macro(ARM_V7S_PTES_PER_LVL) since it is called in ARM_V7S_LVL_IDX which has already used "_l". c) Fix a PM suspend issue: Avoid pm suspend in pm runtime case. v2: https://lore.kernel.org/linux-iommu/20200905080920.13396-1-yong.wu@mediatek.com/ a) Convert IOMMU/SMI dt-binding to DT schema. b) Fix some comment from Pi-Hsun and Nicolas. like use generic_iommu_put_resv_regions. c) Reword some comment, like add how to use domain-id. v1: https://lore.kernel.org/linux-iommu/20200711064846.16007-1-yong.wu@mediatek.com/ Yong Wu (24): dt-bindings: iommu: mediatek: Convert IOMMU to DT schema dt-bindings: memory: mediatek: Add a common larb-port header file dt-bindings: memory: mediatek: Extend LARB_NR_MAX to 32 dt-bindings: memory: mediatek: Add domain definition dt-bindings: mediatek: Add binding for mt8192 IOMMU iommu/mediatek: Use the common mtk-smi-larb-port.h iommu/io-pgtable-arm-v7s: Use ias to check the valid iova in unmap iommu/io-pgtable-arm-v7s: Extend PA34 for MediaTek iommu/io-pgtable-arm-v7s: Clear LVL_SHIFT/BITS macro instead of the formula iommu/io-pgtable-arm-v7s: Add cfg as a param in some macros iommu/io-pgtable-arm-v7s: Quad lvl1 pgtable for MediaTek iommu/mediatek: Move hw_init into attach_device iommu/mediatek: Add device link for smi-common and m4u iommu/mediatek: Add pm runtime callback iommu/mediatek: Add power-domain operation iommu/mediatek: Add iova reserved function iommu/mediatek: Add single domain iommu/mediatek: Support master use iova over 32bit iommu/mediatek: Support up to 34bit iova in tlb flush iommu/mediatek: Support report iova 34bit translation fault in ISR iommu/mediatek: Add support for multi domain iommu/mediatek: Adjust the structure iommu/mediatek: Add mt8192 support MAINTAINERS: Add entry for MediaTek IOMMU .../bindings/iommu/mediatek,iommu.txt | 105 ------- .../bindings/iommu/mediatek,iommu.yaml | 183 ++++++++++++ MAINTAINERS | 9 + drivers/iommu/io-pgtable-arm-v7s.c | 56 ++-- drivers/iommu/mtk_iommu.c | 271 +++++++++++++++--- drivers/iommu/mtk_iommu.h | 11 +- drivers/memory/mtk-smi.c | 8 + include/dt-bindings/memory/mt2712-larb-port.h | 2 +- include/dt-bindings/memory/mt6779-larb-port.h | 2 +- include/dt-bindings/memory/mt8167-larb-port.h | 2 +- include/dt-bindings/memory/mt8173-larb-port.h | 2 +- include/dt-bindings/memory/mt8183-larb-port.h | 2 +- include/dt-bindings/memory/mt8192-larb-port.h | 240 ++++++++++++++++ .../dt-bindings/memory/mtk-smi-larb-port.h | 22 ++ include/linux/io-pgtable.h | 4 +- include/soc/mediatek/smi.h | 3 +- 16 files changed, 735 insertions(+), 187 deletions(-) delete mode 100644 Documentation/devicetree/bindings/iommu/mediatek,iommu.txt create mode 100644 Documentation/devicetree/bindings/iommu/mediatek,iommu.yaml create mode 100644 include/dt-bindings/memory/mt8192-larb-port.h create mode 100644 include/dt-bindings/memory/mtk-smi-larb-port.h -- 2.18.0 _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
