Commit 4287861dca ("dt-bindings: arm-smmu: Add Tegra186 compatible
string") introduced a jsonschema syntax error as a result of a rebase
gone wrong. Fix it.

The ARM SMMU instantiations found on Tegra186 and later need inter-
operation with the memory controller in order to correctly program
stream ID overrides.
Furthermore, on Tegra194 multiple instances of the SMMU can gang up
to achieve higher throughput. In order to do this, they have to be
programmed identically so that the memory controller can interleave
memory accesses between them.
Add the Tegra186 compatible string to make sure the interoperation
with the memory controller can be enabled on that SoC generation.

Every Qcom Adreno GPU has an embedded SMMU for its own use. These
devices depend on unique features such as split pagetables,
different stall/halt requirements and other settings. Identify them
with a compatible string so that they can be identified in the
arm-smmu implementation specific code.

Add specific compatible string for Marvell usage due to errata of
accessing 64bits registers of ARM SMMU, in AP806.
AP806 SoC uses the generic ARM-MMU500, and there's no specific
implementation of Marvell, this compatible is used for errata only.

Including:
- A big part of this is a change in how devices get connected to
IOMMUs in the core code. It contains the change from the old
add_device()/remove_device() to the new
probe_device()/release_device() call-backs. As a result
functionality that was previously in the IOMMU drivers has
been moved to the IOMMU core code, including IOMMU group
allocation for each device.
The reason for this change was to get more robust allocation
of default domains for the iommu groups.
A couple of fixes were necessary after this was merged into
the IOMMU tree, but there are no known bugs left. The last fix
is applied on-top of the merge commit for the topic branches.
- Removal of the driver private domain handling in the Intel
VT-d driver. This was fragile code and I am glad it is gone
now.
- More Intel VT-d updates from Lu Baolu:
- Nested Shared Virtual Addressing (SVA) support to the
Intel VT-d driver
- Replacement of the Intel SVM interfaces to the common
IOMMU SVA API
- SVA Page Request draining support
- ARM-SMMU Updates from Will:
- Avoid mapping reserved MMIO space on SMMUv3, so that
it can be claimed by the PMU driver
- Use xarray to manage ASIDs on SMMUv3
- Reword confusing shutdown message
- DT compatible string updates
- Allow implementations to override the default domain
type
- A new IOMMU driver for the Allwinner Sun50i platform
- Support for ATS gets disabled for untrusted devices (like
Thunderbolt devices). This includes a PCI patch, acked by
Bjorn.
- Some cleanups to the AMD IOMMU driver to make more use of
IOMMU core features.
- Unification of some printk formats in the Intel and AMD IOMMU
drivers and in the IOVA code.
- Updates for DT bindings
- A number of smaller fixes and cleanups.

The Arm SMMUv1 DT binding only allows combining arm,mmu-401 with
arm,smmu-v1, even though the MMU-400 is compatible as well.
Allow this combination as well to let the Arm Juno board pass the test.

json-schema versions draft7 and earlier have a weird behavior in that
any keywords combined with a '$ref' are ignored (silently). The correct
form was to put a '$ref' under an 'allOf'. This behavior is now changed
in the 2019-09 json-schema spec and '$ref' can be mixed with other
keywords. The json-schema library doesn't yet support this, but the
tooling now does a fixup for this and either way works.
This has been a constant source of review comments, so let's change this
treewide so everyone copies the simpler syntax.
Scripted with ruamel.yaml with some manual fixups. Some minor whitespace
changes from the script.

Convert the Arm SMMU binding to DT schema.
The existing binding doc doesn't cover the number of variations of
compatible properties found in .dts files. "qcom,msm8998-smmu-v2" was
also missing, so add it.
SoCFPGA Stratix10 has a single clock defined which doesn't match the
binding. This issue remains.
