Thus, allow "dma-coherent" property to be used for this device. This fixes a part of the following error (the second part is fixed in the next commit): pcie-ep@1c10000: Unevaluated properties are not allowed ('dma-coherent', 'iommus' were unexpected) Fixes: 4b220c6fa9f3 ("arm64: dts: qcom: sa8775p: Mark PCIe EP controller as cache coherent") Signed-off-by: Dmitry Baryshkov Reviewed-by: Krzysztof Kozlowski Reviewed-by: Manivannan Sadhasivam Link: https://lore.kernel.org/r/20250221-sar2130p-pci-v3-1-61a0fdfb75b4@linaro.org [kwilczynski: commit log] Signed-off-by: Krzysztof Wilczyński --- diff --git a/Documentation/devicetree/bindings/pci/qcom,pcie-ep.yaml b/Documentation/devicetree/bindings/pci/qcom,pcie-ep.yaml index 1226ee5d08d1a..0c2ca4cfa3b19 100644 --- a/Documentation/devicetree/bindings/pci/qcom,pcie-ep.yaml +++ b/Documentation/devicetree/bindings/pci/qcom,pcie-ep.yaml @@ -91,6 +91,8 @@ properties: - const: pcie-mem - const: cpu-pcie + dma-coherent: true + resets: maxItems: 1
