| Microchip KSZ Series Ethernet switches
| ==================================
|
| Required properties:
|
| - compatible: For external switch chips, compatible string must be exactly one
| of the following:
| - "microchip,ksz9477"
| - "microchip,ksz9897"
|
| See Documentation/devicetree/bindings/net/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;
| };
| };
| };
| };
| };
