[PATCH v7 01/14] iommu/rockchip: Prohibit unbind and remove

Removal of IOMMUs cannot be done reliably. This is similar to exynos iommu driver. Signed-off-by: Jeffy Chen <jeffy.c...@rock-chips.com> Reviewed-by: Tomasz Figa <tf...@chromium.org> --- Changes in v7: None Changes in v6: None Changes in v5: None Changes in v4: Rewrite commit messa

[PATCH v7 14/14] iommu/rockchip: Support sharing IOMMU between masters

There would be some masters sharing the same IOMMU device. Put them in the same iommu group and share the same iommu domain. Signed-off-by: Jeffy Chen <jeffy.c...@rock-chips.com> Reviewed-by: Robin Murphy <robin.mur...@arm.com> --- Changes in v7: Use iommu_group_ref_get to av

[PATCH v7 11/14] iommu/rockchip: Use OF_IOMMU to attach devices automatically

Converts the rockchip-iommu driver to use the OF_IOMMU infrastructure, which allows attaching master devices to their IOMMUs automatically according to DT properties. Signed-off-by: Jeffy Chen <jeffy.c...@rock-chips.com> Reviewed-by: Robin Murphy <robin.mur...@arm.com> --- Changes

[PATCH v7 10/14] iommu/rockchip: Use IOMMU device for dma mapping operations

Use the first registered IOMMU device for dma mapping operations, and drop the domain platform device. This is similar to exynos iommu driver. Signed-off-by: Jeffy Chen <jeffy.c...@rock-chips.com> Reviewed-by: Tomasz Figa <tf...@chromium.org> Reviewed-by: Robin Murphy <robin

[PATCH v7 13/14] iommu/rockchip: Add runtime PM support

When the power domain is powered off, the IOMMU cannot be accessed and register programming must be deferred until the power domain becomes enabled. Add runtime PM support, and use runtime PM device link from IOMMU to master to startup and shutdown IOMMU. Signed-off-by: Jeffy Chen <jeff
