4fff78dc24 dt-bindings: arm-smmu: Document SM8[45]50 GPU SMMU 
SM8450 and SM8550 both use a Qualcomm-modified MMU500 for their GPU.
In both cases, it requires a set of clocks to be enabled. Describe that.

SDM630 was abusingly referencing one of the internal bus clocks, that
were recently dropped from Linux (because the original implementation
did not make much sense), circumventing the interconnect framework.

1. SMMUs with platform-specific compatibles which list explicit clocks
   and clock-names,
2. SMMUs using only generic compatibles, e.g. arm,mmu-500, which have a

This requires such variants with platform-specific compatible, to
explicitly list the clocks or omit them, making the binding more
constraint.

expected that all future platforms will use the generic qcom,smmu-500

Note: I have split the sdx55 and sdx65 from the legacy bindings. They

they are using the generic implementation rather than the
Qualcomm-speicific one.

4287861dca dt-bindings: arm-smmu: Add Tegra186 compatible string 
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.

4e3a16ee91 Merge tag 'iommu-updates-v5.8' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu 
Pull iommu updates from Joerg Roedel:
 "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.

  Other than that change, we have:

   - 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.
