fsl,pcie-scfg actually need an argument when there are more than one PCIe instances. Change it to phandle-array and use items to describe each field means. Fix below warning. arch/arm64/boot/dts/freescale/fsl-ls1043a-rdb.dtb: pcie@3400000: fsl,pcie-scfg:0: [22, 0] is too long from schema $id: http://devicetree.org/schemas/pci/fsl,layerscape-pcie.yaml# Signed-off-by: Frank Li <Frank.Li@xxxxxxx> --- Change from v1 to v2 - update commit message. --- .../devicetree/bindings/pci/fsl,layerscape-pcie.yaml | 8 +++++++- 1 file changed, 7 insertions(+), 1 deletion(-) diff --git a/Documentation/devicetree/bindings/pci/fsl,layerscape-pcie.yaml b/Documentation/devicetree/bindings/pci/fsl,layerscape-pcie.yaml index 793986c5af7ff..679c2989de7a2 100644 --- a/Documentation/devicetree/bindings/pci/fsl,layerscape-pcie.yaml +++ b/Documentation/devicetree/bindings/pci/fsl,layerscape-pcie.yaml @@ -43,10 +43,16 @@ properties: - const: config fsl,pcie-scfg: - $ref: /schemas/types.yaml#/definitions/phandle + $ref: /schemas/types.yaml#/definitions/phandle-array description: A phandle to the SCFG device node.
