2020-05-07iommu/arm-smmu: Allow client devices to select direct mappingJordan Crouse
Some client devices want to directly map the IOMMU themselves instead of using the DMA domain. Allow those devices to opt in to direct mapping by way of a list of compatible strings.

2020-05-07iommu: arm-smmu-impl: Convert to a generic reset implementationSai Prakash Ranjan
Currently the QCOM specific smmu reset implementation is very specific to SDM845 SoC and has a wait-for-safe logic which may not be required for other SoCs. So move the SDM845 specific logic to its specific reset function. Also add SC7180 SMMU compatible for calling into QCOM specific implementation.

With no default domain iommu_group_create_direct_mappings() will do nothing and no direct mappings will be created.

2020-05-05iommu: Split off default domain allocation from group assignmentJoerg Roedel
When a bus is initialized with iommu-ops, all devices on the bus are scanned and iommu-groups are allocated for them, and each groups will also get a default domain allocated. Until now this happened as soon as the group was created and the first device added to it. When other devices with different default domain requirements were added to the group later on, the default domain was re-allocated, if possible. This resulted in some back and forth and unnecessary allocations, so change the flow to defer default domain allocation until all devices have been added to their respective IOMMU groups. The default domains are allocated for newly allocated groups after each device on the bus is handled and was probed by the IOMMU driver.

2020-05-05iommu: Move default domain allocation to iommu_probe_device()Joerg Roedel
Well, not really. The call to iommu_alloc_default_domain() in iommu_group_get_for_dev() has to stay around as long as there are IOMMU drivers using the add/remove_device() call-backs instead of probe/release_device(). Those drivers expect that iommu_group_get_for_dev() returns the device attached to a group and the group set up with a default domain (and the device attached to the groups current domain).

2020-05-05iommu: Add def_domain_type() callback in iommu_opsSai Praneeth Prakhya
Some devices are reqired to use a specific type (identity or dma) of default domain when they are used with a vendor iommu. When the system level default domain type is different from it, the vendor iommu driver has to request a new default domain with iommu_request_dma_domain_for_dev() and iommu_request_dm_for_dev() in the add_dev() callback. Unfortunately, these two helpers only work when the group hasn't been assigned to any other devices, hence, some vendor iommu driver has to use a private domain if it fails to request a new default one. This adds def_domain_type() callback in the iommu_ops, so that any special requirement of default domain for a device could be aware by the iommu generic layer.

2020-04-26firmware_loader: revert removal of the fw_fallback_config exportLuis Chamberlain
Christoph's patch removed two unsused exported symbols, however, one symbol is used by the firmware_loader itself. If CONFIG_FW_LOADER=m so the firmware_loader is modular but CONFIG_FW_LOADER_USER_HELPER=y we fail the build at mostpost. ERROR: modpost: "fw_fallback_config" [drivers/base/firmware_loader/firmware_class.ko] undefined! This happens because the variable fw_fallback_config is built into the kernel if CONFIG_FW_LOADER_USER_HELPER=y always, so we need to grant access to the firmware loader module by exporting it. Revert only one hunk from his patch.
