If anyone has any objections, please let me know. ------------------ From: Manivannan Sadhasivam [ Upstream commit d2e56fb42e3d10d7e711063cdc00523ddb31d544 ] The IOMMU provider apps_smmu uses '#iommu-cells = <2>', but the PCIe iommu-map entries specify only one cell for the SID, omitting the SID mask. This went unnoticed until the OF core started warning with commit ccb2fd725d41 ("of: Respect #{iommu,msi}-cells in maps"): iommu-map has 1-cell entries targeting 2-cell #iommu-cells, treating as 1-cell output So fix the entries to match the provider's '#iommu-cells' property.
