* iommu/tegra: gart: Fix register offset correctlyHiroshi DOYU2012-05-111-3/+4
| | | | | | | | | | 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.

* ARM: IOMMU: Tegra20: Add iommu_ops for GART driverHiroshi DOYU2012-01-261-0/+451
Tegra 20 IOMMU H/W, GART (Graphics Address Relocation Table). This patch implements struct iommu_ops for GART for the upper IOMMU API. This H/W module supports only single virtual address space(domain), and manages a single level 1-to-1 mapping H/W translation page table.
