* iommu/tegra-gart: Staticize tegra_gart_pm_opsSachin Kamat2013-11-011-1/+1

* iommu/tegra: gart: cleanup devm_* functions usageWei Yongjun2013-09-241-17/+2Star
| | | | | | | | | | The devm_[kzalloc|ioremap] functions allocates data that are released when a driver detaches. Thus, there is no reason to explicitly call devm_[kfree|iounmap] in probe or remove functions.

* iommu/tegra: Print phys_addr_t using %paThierry Reding2013-09-241-3/+3
| | | | | | | | | | | When enabling LPAE on ARM, phys_addr_t becomes 64 bits wide and printing a variable of that type using a simple %x format specifier causes the compiler to complain. Change the format specifier to %pa, which is used specifically for variables of type phys_addr_t.

* Drivers: iommu: remove __dev* attributes.Greg Kroah-Hartman2013-01-041-2/+2
| | | | | | | | | | | | | | | | | | | | | | | CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

* 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.
