However, all DTS files provide interrupts properties, and thus fail to validate. Fix this by documenting the interrupts property. Fixes: 5be478f9c24fbdf8 ("dt-bindings: Another round of adding missing 'additionalProperties'") Fixes: 4c0f80920923f103 ("dt-bindings: PCI: rcar: Add bindings for R-Car PCIe endpoint controller") Signed-off-by: Geert Uytterhoeven Reviewed-by: Lad Prabhakar --- Alternatively, the interrupts properties should be removed from the corresponding device nodes in the DTS files. Obviously they should be retained in the device nodes representing PCIe controllers configured in host mode, which describe the same hardware... --- Documentation/devicetree/bindings/pci/rcar-pci-ep.yaml | 9 +++++++++ 1 file changed, 9 insertions(+) diff --git a/Documentation/devicetree/bindings/pci/rcar-pci-ep.yaml b/Documentation/devicetree/bindings/pci/rcar-pci-ep.yaml index fb97f4ea0e63682b..32a3b7665ff5473c 100644 --- a/Documentation/devicetree/bindings/pci/rcar-pci-ep.yaml +++ b/Documentation/devicetree/bindings/pci/rcar-pci-ep.yaml @@ -33,6 +33,10 @@ properties: - const: memory2 - const: memory3 + interrupts: + minItems: 3 + maxItems: 3 + power-domains: maxItems: 1 @@ -54,6 +58,7 @@ required: - compatible - reg - reg-names + - interrupts - resets - power-domains - clocks @@ -65,6 +70,7 @@ additionalProperties: false examples: - | #include + #include #include pcie0_ep: pcie-ep@fe000000 { @@ -76,6 +82,9 @@ examples: <0x30000000 0x8000000>, <0x38000000 0x8000000>; reg-names = "apb-base", "memory0", "memory1", "memory2", "memory3"; + interrupts = , + , + ; resets = <&cpg 319>; power-domains = <&sysc R8A774C0_PD_ALWAYS_ON>; clocks = <&cpg CPG_MOD 319>;
