+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 {
+ reg = <7>
+ speed = <1000>;
+ duplex-full;
+ };
+ };
+
+ spi1: spi@f8008000 {
+ pinctrl-0 = <&pinctrl_spi_ksz>;
+ cs-gpios = <&pioC 25 0>;
+ id = <1>;
+ status = "okay";
4 lines above should be indented more to the right.
+
+ ksz9477: ksz9477@0 {
+ compatible = "microchip,ksz9477";
+ reg = <0>;
+
+ spi-max-frequency = <44000000>;
+ spi-cpha;
+ spi-cpol;
+
+ status = "okay";
+ 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 = <&macb0>;
+ fixed-link {
+ speed = <1000>;
+ full-duplex;
+ };
+ };
+ };
+ };
+ };
Unmatched }?
