2019-02-11	iommu: Allow io-pgtable to be used outside of drivers/iommu/	Rob Herring	1	-2/+3
	Move io-pgtable.h to include/linux/ and export alloc_io_pgtable_ops and free_io_pgtable_ops. This enables drivers outside drivers/iommu/ to use the page table library. Specifically, some ARM Mali GPUs use the ARM page table formats.

2016-02-17	iommu/io-pgtable: Add helper functions for TLB ops	Robin Murphy	1	-1/+1
	Add some simple wrappers to avoid having the guts of the TLB operations spilled all over the page table implementations, and to provide a point to implement extra common functionality.

2016-02-17	iommu/io-pgtable: Add ARMv7 short descriptor support	Robin Murphy	1	-0/+3
	Add a nearly-complete ARMv7 short descriptor implementation, omitting only a few legacy and CPU-centric aspects which shouldn't be necessary for IOMMU API use anyway.

2015-01-19	iommu: add ARM LPAE page table allocator	Will Deacon	1	-0/+11
	A number of IOMMUs found in ARM SoCs can walk architecture-compatible page tables. This patch adds a generic allocator for Stage-1 and Stage-2 v7/v8 long-descriptor page tables. 4k, 16k and 64k pages are supported, with up to 4-levels of walk to cover a 48-bit address space.

2015-01-19	iommu: introduce generic page table allocation framework	Will Deacon	1	-0/+71
	This patch introduces a generic framework for allocating page tables for an IOMMU. There are a number of reasons we want to do this: - It avoids duplication of complex table management code in IOMMU drivers that use the same page table format - It removes any coupling with the CPU table format (and even the architecture!) - It defines an API for IOMMU TLB maintenance Tested-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Will Deacon <will.deacon@arm.com>
