iommu/tegra: gart: Set aperture at domain initialization time

2015-03-31T14:34:12+00:00

The aperture of the domain should always be available, otherwise drivers need to attach first before they can use the aperture geometry. Cc: Hiroshi Doyu Signed-off-by: Thierry Reding Signed-off-by: Joerg Roedel

iommu/tegra-gart: Make use of domain_alloc and domain_free

2015-03-31T13:32:12+00:00

Implement domain_alloc and domain_free iommu-ops as a replacement for domain_init/domain_destroy. Tested-by: Thierry Reding Acked-by: Thierry Reding Signed-off-by: Joerg Roedel

iommu/tegra: gart: Provide default ->map_sg() callback

2015-01-26T12:41:07+00:00

Commit 315786ebbf4a ("iommu: Add iommu_map_sg() function") adds a new ->map_sg() callback and provides a default implementation that drivers can use until they implement a hardware-specific variant. Unfortunately the Tegra GART driver was not updated as part of that commit, so that iommu_map_sg() calls on a domain provided by the GART cause an oops.

iommu/tegra: gart: Do not register with bus

2015-01-26T12:41:07+00:00

The driver currently doesn't work as expected and causes existing setups with Tegra20 to break after commit df06b759f2cf ("drm/tegra: Add IOMMU support"). To restore these setups, do not register the operations with the platform bus for now. Fixing this properly will involve non-trivial changes to the DRM driver, which are unlikely to be accepted at this point in the release cycle.

iommu: drop owner assignment from platform_drivers

2014-10-20T14:20:42+00:00

A platform_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Wolfram Sang

iommu: Make of_device_id array const

Make of_device_id array const, because all OF functions handle it as const. Signed-off-by: Kiran Padwal Signed-off-by: Joerg Roedel
