The Arm SMMU drivers are getting fat on vendor value-add, so move them to their own subdirectory out of the way of the other IOMMU drivers. Suggested-by: Joerg Roedel Signed-off-by: Will Deacon

iommu/arm-smmu: add NVIDIA implementation for ARM MMU-500 usage

2020-07-20T08:30:50Z

NVIDIA's Tegra194 SoC has three ARM MMU-500 instances. It uses two of the ARM MMU-500s together to interleave IOVA accesses across them and must be programmed identically. This implementation supports programming the two ARM MMU-500s that must be programmed identically. The third ARM MMU-500 instance is supported by standard arm-smmu.c driver itself.

iommu: Add Allwinner H6 IOMMU driver

2020-05-14T15:48:57Z

The Allwinner H6 has introduced an IOMMU for a few DMA controllers, mostly video related: the display engine, the video decoders / encoders, the camera capture controller, etc. The design is pretty simple compared to other IOMMUs found in SoCs: there's a single instance, controlling all the masters, with a single address space. It also features a performance monitoring unit that allows to retrieve various informations (per-master and global TLB accesses, hits and misses, access latency, etc) that isn't supported at the moment.

iommu/arm-smmu: Restore naming of driver parameter prefix

2020-02-19T11:03:21Z

Extending the Arm SMMU driver to allow for modular builds changed KBUILD_MODNAME to be "arm_smmu_mod" so that a single module could be built from the multiple existing object files without the need to rename any source files. This inadvertently changed the name of the driver parameters, which may lead to runtime issues if bootloaders are relying on the old names for correctness (e.g. "arm-smmu.disable_bypass=0"). Although MODULE_PARAM_PREFIX can be overridden to restore the old naming for builtin parameters, only the new name is matched by modprobe and so loading the driver as a module would cause parameters specified on the kernel command line to be ignored. Instead, rename "arm_smmu_mod" to "arm_smmu". Whilst it's a bit of a bodge, this allows us to create a single module without renaming any files and makes use of the fact that underscores and hyphens can be used interchangeably in parameter names.
