Subject: [PATCH 1/2] dt-bindings: arm-smmu: Fix json-schema for Tegra
Date: Wed, 1 Dec 2021 15:57:15 +0000	[thread overview]
Message-ID: <20211201155716.149543-1-jonathanh@nvidia.com> (raw)

The dt_binding_check currently issues the following warnings for the
Tegra186 and Tegra194 SMMUs ...

 arch/arm64/boot/dts/nvidia/tegra186-p2771-0000.dt.yaml: iommu@12000000:
  '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-p3509-0000+p3636-0001.dt.yaml
  CHECK   arch/arm64/boot/dts/nvidia/tegra186-p3509-0000+p3636-0001.dt.yaml

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