No, because there is nothing to select it. Just put a wrong value for qcom,package-mode and see. ethernet-phy-package.yaml will be applied, but since it allows any extra properties not much is tested. > +properties: > + qcom,package-mode: > + enum: > + - qsgmii > + - psgmii description needed.

The addresses are MDIO, but you have just 0-4. Might be correct or might not? In any case, the unit-address should be restricted to '@1?[0-9a-f]$'. Though that belongs in mdio.yaml and here '^ethernet-phy@' is sufficient (once there's a reference to mdio.yaml). > + $ref: ethernet-phy.yaml# > + > + properties: > + gpio-controller: > + description: set the output lines as GPIO instead of LEDs > + type: boolean > + > + '#gpio-cells': > + description: number of GPIO cells for the PHY > + const: 2 > + > + dependencies: > + gpio-controller: ['#gpio-cells'] No need for this, the common gpio schema does this. > + > + if: > + required: > + - gpio-controller > + then: > + properties: > + leds: false > + > + unevaluatedProperties: false Move under $ref. > + > +unevaluatedProperties: false > + > +examples: > + - | > + #include <dt-bindings/leds/common.h> > + > + mdio { > + #address-cells = <1>; > + #size-cells = <0>; > + > + ethernet-phy-package@0 { > + #address-cells = <1>; > + #size-cells = <0>; > + compatible = "ethernet-phy-package"; > + reg = <0>; > + > + qcom,package-mode = "qsgmii"; Nothing in here tells me this is a QCA807X other than this property (sort of).
