* documentation/iommu: Add note on existing DT binding statusShaik Ameer Basha2014-05-141-0/+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.

| |/ |/| | | | | | | | | | | | | | | | | | | | | 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'.

* iommu/tegra: smmu: Add device tree support for SMMUHiroshi Doyu2012-06-251-0/+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.

* iommu/tegra: gart: Fix register offset correctlyHiroshi DOYU2012-05-111-3/+3
| | | | | | | | | | DT passes the exact GART register ranges without any overlapping with MC register ranges. GART register offset needs to be adjusted by one passed by DT correctly.
