We could merge the first 6 patches with no issues, since there aren't any callers of of_iommu_init without patch 7 anyway. Up to you. Will --->8 Marek Szyprowski (1): iommu: fix initialization without 'add_device' callback Will Deacon (7): iommu: provide early initialisation hook for IOMMU drivers dma-mapping: replace set_arch_dma_coherent_ops with arch_setup_dma_ops iommu: add new iommu_ops callback for adding an OF device iommu: provide helper function to configure an IOMMU for an of master dma-mapping: detect and configure IOMMU in of_dma_configure arm: call iommu_init before of_platform_populate arm: dma-mapping: plumb our iommu mapping ops into arch_setup_dma_ops arch/arm/include/asm/dma-mapping.h | 12 +++--- arch/arm/kernel/setup.c | 2 + arch/arm/mm/dma-mapping.c | 83 ++++++++++++++++++++++++++++++++++---- drivers/iommu/Kconfig | 2 +- drivers/iommu/iommu.c | 2 +- drivers/iommu/of_iommu.c | 50 +++++++++++++++++++++++ drivers/of/platform.c | 50 ++++++++++++----------- include/asm-generic/vmlinux.lds.h | 2 + include/linux/dma-mapping.h | 13 +++--- include/linux/iommu.h | 8 ++++ include/linux/of_iommu.h | 31 ++++++++++++++ 11 files changed, 211 insertions(+), 44 deletions(-) -- 2.1.1
