EMDIO supports both Clause 22 and 45 protocols. And the EMDIO provides a means for different software modules to share a single set of MDIO signals to access their PHYs. maintainers: - Frank Li - Vladimir Oltean - Wei Fang - Claudiu Manoil properties: compatible: items: - enum: - pci1957,ee01 - const: fsl,enetc-mdio reg: maxItems: 1 required: - compatible - reg allOf: - $ref: mdio.yaml - $ref: /schemas/pci/pci-device.yaml unevaluatedProperties: false examples: - | pcie{ #address-cells = <3>; #size-cells = <2>; mdio@0,3 { compatible = "pci1957,ee01", "fsl,enetc-mdio"; reg = <0x000300 0 0 0 0>; #address-cells = <1>; #size-cells = <0>; ethernet-phy@2 { reg = <0x2>; }; }; };
