From 82a10eb6aeab412abd83a57cc3a605213d1dc1d5 Mon Sep 17 00:00:00 2001 From: Manivannan Sadhasivam Date: Thu, 30 Jul 2026 13:56:00 +0200 Subject: [PATCH] arm64: dts: qcom: qcs6490-radxa-dragon-q6a: Fix the PCIe iommu-map entries 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.
