In an effort to give some love to the apparently forgotten MT6795 SoC, I am upstreaming more components that are necessary to support platforms powered by this one apart from a simple boot to serial console. This series introduces support for the IOMMUs found on this SoC. Tested on a MT6795 Sony Xperia M5 (codename "Holly") smartphone. Changes in v4: - Retitled mtk_iommu commits to iommu/mediatek as suggested by Yong Wu - Removed unused M4U_LARB5_ID definition - Rebased on next-20220624 and https://patchwork.kernel.org/project/linux-mediatek/list/?series=650969 Changes in v3: - Added new flag as suggested by Yong Wu - Rebased on top of https://patchwork.kernel.org/project/linux-mediatek/list/?series=648784 Changes in v2: - Rebased on top of https://patchwork.kernel.org/project/linux-mediatek/list/?series=642681 AngeloGioacchino Del Regno (3): dt-bindings: mediatek: Add bindings for MT6795 M4U iommu/mediatek: Introduce new flag TF_PORT_TO_ADDR_MT8173 iommu/mediatek: Add support for MT6795 Helio X10 M4Us .../bindings/iommu/mediatek,iommu.yaml | 4 + drivers/iommu/mtk_iommu.c | 21 +++- include/dt-bindings/memory/mt6795-larb-port.h | 95 +++++++++++++++++++ 3 files changed, 118 insertions(+), 2 deletions(-) create mode 100644 include/dt-bindings/memory/mt6795-larb-port.h -- 2.35.1
