2012-07-11iommu/msm: Implement DOMAIN_ATTR_GEOMETRY attributeJoerg Roedel
Implement the attribute for the MSM IOMMU driver. Acked-by: David Brown <davidb@codeaurora.org> Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2012-01-30iommu/msm: Fix error handling in msm_iommu_unmap()Joerg Roedel
Error handling in msm_iommu_unmap() is broken. On some error conditions retval is set to a non-zero value which causes the function to return 'len' at the end. This hides the error from the user. Zero should be returned in those error cases.

2011-11-10iommu/msm: announce supported page sizesOhad Ben-Cohen
Let the IOMMU core know we support 4KiB, 64KiB, 1MiB and 16MiB page sizes. This way the IOMMU core can split any arbitrary-sized physically contiguous regions (that it needs to map) as needed.

2011-11-10iommu/core: stop converting bytes to page order back and forthOhad Ben-Cohen
Express sizes in bytes rather than in page order, to eliminate the size->order->size conversions we have whenever the IOMMU API is calling the low level drivers' map/unmap methods. Adopt all existing drivers.

2011-10-21iommu/msm: Use bus_set_iommu instead of register_iommuJoerg Roedel
Convert the MSM IOMMU driver for ARM to use the new interface for publishing the iommu_ops. Acked-by: David Brown <davidb@codeaurora.org> Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2011-09-05iommu/msm: ->unmap() should return order of unmapped pageOhad Ben-Cohen
Users of the IOMMU API (kvm specifically) assume that iommu_unmap() returns the order of the unmapped page (on success). Fix msm_iommu_unmap() accordingly.

2011-06-21msm: iommu: move to drivers/iommu/Ohad Ben-Cohen
This should ease finding similarities with different platforms, with the intention of solving problems once in a generic framework which everyone can use. Compile-tested for MSM8X60.
