Merge tag 'of-iommu-configure' of git://git.kernel.org/pub/scm/linux/kernel/git/will/linux into next/iommu-config
Pull "Automatic DMA configuration for OF-based IOMMU masters" from Will Deacon:
This series adds automatic IOMMU and DMA-mapping configuration for
OF-based DMA masters described using the generic IOMMU devicetree
bindings. Although there is plenty of future work around splitting up
iommu_ops, adding default IOMMU domains and sorting out automatic IOMMU
group creation for the platform_bus, this is already useful enough for
people to port over their IOMMU drivers and start using the new probing
infrastructure (indeed, Marek has patches queued for the Exynos IOMMU).
* tag 'of-iommu-configure' of git://git.kernel.org/pub/scm/linux/kernel/git/will/linux:
iommu: store DT-probed IOMMU data privately
arm: dma-mapping: plumb our iommu mapping ops into arch_setup_dma_ops
arm: call iommu_init before of_platform_populate
dma-mapping: detect and configure IOMMU in of_dma_configure
iommu: fix initialization without 'add_device' callback
iommu: provide helper function to configure an IOMMU for an of master
iommu: add new iommu_ops callback for adding an OF device
dma-mapping: replace set_arch_dma_coherent_ops with arch_setup_dma_ops
iommu: provide early initialisation hook for IOMMU drivers
