2013-08-06	iommu/msm: Move mach includes to iommu directory	Stephen Boyd	1	-2/+2
	Two header files exist in mach-msm's include/mach directory that are only used by the MSM iommu driver. Move these files to the iommu driver directory and prefix them with "msm_". This allows us to compile the MSM iommu driver on multi-platform kernels.

2013-04-02	iommu/fsl: Make iova dma_addr_t in the iommu_iova_to_phys API.	Varun Sethi	1	-1/+1
	This is required in case of PAMU, as it can support a window size of up to 64G (even on 32bit). Signed-off-by: Varun Sethi <Varun.Sethi@freescale.com> Signed-off-by: Joerg Roedel <joro@8bytes.org>
2012-07-11	iommu/msm: Implement DOMAIN_ATTR_GEOMETRY attribute	Joerg Roedel	1	-0/+5
	Implement the attribute for the MSM IOMMU driver. Acked-by: David Brown <davidb@codeaurora.org> Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2012-01-30	iommu/msm: Fix error handling in msm_iommu_unmap()	Joerg Roedel	1	-6/+1
	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.

2011-11-10	iommu/msm: announce supported page sizes	Ohad Ben-Cohen	1	-1/+5
	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.

2011-11-10	iommu/core: stop converting bytes to page order back and forth	Ohad Ben-Cohen	1	-12/+7
	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.

2011-10-21	iommu/msm: Use bus_set_iommu instead of register_iommu	Joerg Roedel	1	-1/+1
	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>
2011-09-05	iommu/msm: ->unmap() should return order of unmapped page	Ohad Ben-Cohen	1	-0/+7
	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.

2011-06-21	msm: iommu: move to drivers/iommu/	Ohad Ben-Cohen	1	-0/+731
	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.
