When child bus is selected, one needs to select these two 16 properties as well to generate desired MDIO transaction on appropriate bus. 17 18allOf: 19 - $ref: /schemas/net/mdio-mux.yaml# 20 21properties: 22 compatible: 23 const: brcm,mdio-mux-iproc 24 25 reg: 26 maxItems: 1 27 28 clocks: 29 maxItems: 1 30 description: core clock driving the MDIO block 31 32 33required: 34 - compatible 35 - reg 36 37unevaluatedProperties: false 38 39examples: 40 - | 41 mdio_mux_iproc: mdio-mux@66020000 { 42 compatible = "brcm,mdio-mux-iproc"; 43 reg = <0x66020000 0x250>; 44 #address-cells = <1>; 45 #size-cells = <0>; 46 47 mdio@0 { 48 reg = <0x0>; 49 #address-cells = <1>; 50 #size-cells = <0>; 51 52 pci_phy0: pci-phy@0 { 53 compatible = "brcm,ns2-pcie-phy"; 54 reg = <0x0>; 55 #phy-cells = <0>; 56 }; 57 }; 58 59 mdio@7 { 60 reg = <0x7>; 61 #address-cells = <1>; 62 #size-cells = <0>; 63 64 pci_phy1: pci-phy@0 { 65 compatible = "brcm,ns2-pcie-phy"; 66 reg = <0x0>; 67 #phy-cells = <0>; 68 }; 69 }; 70 71 mdio@10 { 72 reg = <0x10>; 73 #address-cells = <1>; 74 #size-cells = <0>; 75 76 gphy0: eth-phy@10 { 77 reg = <0x10>; 78 }; 79 }; 80 }; 81
