2014-07-31devicetree: Add generic IOMMU device tree bindingsThierry Reding1-0/+182
This commit introduces a generic device tree binding for IOMMU devices. Only a very minimal subset is described here, but it is enough to cover the requirements of both the Exynos System MMU and Tegra SMMU as discussed here: https://lkml.org/lkml/2014/4/27/346 Acked-by: Will Deacon <will.deacon@arm.com> Reviewed-by: Arnd Bergmann <arnd@arndb.de> Acked-by: Rob Herring <robh@kernel.org> Signed-off-by: Thierry Reding <treding@nvidia.com> Reviewed-by: Mark Rutland <mark.rutland@arm.com> Reviewed-by: Olof Johansson <olof@lixom.net> Acked-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Joerg Roedel <jroedel@suse.de>
2014-07-03iommu/arm-smmu: remove support for chained SMMUsWill Deacon1-6/+0
The ARM SMMU driver has supported chained SMMUs (i.e. SMMUs connected back-to-back in series) via the smmu-parent property in device tree. This was in anticipation of somebody building such a configuration, however that seems not to be the case. This patch removes the unused chained SMMU hack from the driver. We can consider adding it back later if somebody decided they need it, but for the time being it's just pointless mess that we're carrying in mainline. Removal of the feature also makes migration to the generic IOMMU bindings easier. Signed-off-by: Will Deacon <will.deacon@arm.com>
2014-05-14documentation/iommu: Add note on existing DT binding statusShaik Ameer Basha1-0/+5
The current dt binding for Exynos System MMU can be changed, if found incompatible with the support for "Generic IOMMU Binding". This patch adds a note to the binding documentation stating the same.

2014-03-04Documentation: dt: add OMAP iommu bindingsFlorian Vaussard1-0/+26
This patch adds the iommu bindings for all OMAP2+ SoCs. Apart from the standard bindings used by OMAP peripherals, this patch uses a 'dma-window' (already used by Tegra SMMU) and adds two OMAP custom bindings - 'ti,#tlb-entries' and 'ti,iommu-bus-err-back'.

2012-06-25iommu/tegra: smmu: Add device tree support for SMMUHiroshi Doyu1-0/+21
The necessary info is expected to pass from DT. For more precise resource reservation, there shouldn't be any overlapping of register range between SMMU and MC. SMMU register offset needs to be calculated correctly, based on its register bank.

2012-05-11iommu/tegra: gart: Fix register offset correctlyHiroshi DOYU1-3/+3
