Microchip KSZ Series Ethernet switches ================================== Required properties: - compatible: For external switch chips, compatible string must be exactly one of: "microchip,ksz9477" See Documentation/devicetree/bindings/dsa/dsa.txt for a list of additional required and optional properties. Examples: Ethernet switch connected via SPI to the host, CPU port wired to eth0: eth0: ethernet@10001000 { fixed-link { speed = <1000>; full-duplex; }; }; spi1: spi@f8008000 { pinctrl-0 = <&pinctrl_spi_ksz>; cs-gpios = <&pioC 25 0>; id = <1>; ksz9477: ksz9477@0 { compatible = "microchip,ksz9477"; reg = <0>; spi-max-frequency = <44000000>; spi-cpha; spi-cpol; ports { #address-cells = <1>; #size-cells = <0>; port@0 { reg = <0>; label = "lan1"; }; port@1 { reg = <1>; label = "lan2"; }; port@2 { reg = <2>; label = "lan3"; }; port@3 { reg = <3>; label = "lan4"; }; port@4 { reg = <4>; label = "lan5"; }; port@5 { reg = <5>; label = "cpu"; ethernet = <ð0>; fixed-link { speed = <1000>; full-duplex; }; }; }; }; };
