Thierry sent the same change, but made it required. That's not a
compatible change, but could be justified. Please sort out which one
you need applied.

[PATCH 1/2] dt-bindings: arm-smmu: Fix json-schema for Tegra

2021-12-01 Thread Jon Hunter via iommu 
The dt_binding_check currently issues the following warnings for the
Tegra186 and Tegra194 SMMUs ...

 arch/arm64/boot/dts/nvidia/tegra186-p2771-.dt.yaml: iommu@1200:
  'nvidia,memory-controller' does not match any of the regexes: 'pinctrl-[0-9]+'
From schema: Documentation/devicetree/bindings/iommu/arm,smmu.yaml
  DTC arch/arm64/boot/dts/nvidia/tegra186-p3509-+p3636-0001.dt.yaml
  CHECK   arch/arm64/boot/dts/nvidia/tegra186-p3509-+p3636-0001.dt.yaml

Add the missing 'nvidia,memory-controller' property to fix the above
warning.
