+Broadcom BCM53xx Ethernet switches
+==================================
+
+Required properties:
+
+- compatible: For external switch chips, compatible string must be exactly one
+ of: "brcm,bcm5325"
+ "brcm,bcm53115"
+ "brcm,bcm53125"
+ "brcm,bcm53128"
+ "brcm,bcm5365"
+ "brcm,bcm5395"
+ "brcm,bcm5397"
+ "brcm,bcm5398"
+
+ For the BCM5310x SoCs with an integrated switch, must be one of:
+ "brcm,bcm53010-srab"
+ "brcm,bcm53011-srab"
+ "brcm,bcm53012-srab"
+ "brcm,bcm53018-srab"
+ "brcm,bcm53019-srab" and the mandatory "brcm,bcm5301x-srab" string
+
+ For the BCM585xx/586XX/88312 SoCs with an integrated switch, must be one of:
+ "brcm,bcm58522-srab"
+ "brcm,bcm58523-srab"
+ "brcm,bcm58525-srab"
+ "brcm,bcm58622-srab"
+ "brcm,bcm58623-srab"
+ "brcm,bcm58625-srab"
+ "brcm,bcm88312-srab" and the mandatory "brcm,nsp-srab string
+
+ For the BCM63xx/33xx SoCs with an integrated switch, must be one of:
+ "brcm,bcm3384-switch"
+ "brcm,bcm6328-switch"
+ "brcm,bcm6368-switch" and the mandatory "brcm,bcm63xx-switch"
+
+See Documentation/devicetree/bindings/dsa/dsa.txt for a list of additional
+required and optional properties.
+
+Examples:
+
+Ethernet switch connected via MDIO to the host, CPU port wired to eth0:
+
+ eth0: ethernet@10001000 {
+ compatible = "brcm,unimac";
+ reg = <0x10001000 0x1000>;
+
+ fixed-link {
+ speed = <1000>;
+ duplex-full;
+ };
+ };
+
+ mdio0: mdio@10000000 {
+ compatible = "brcm,unimac-mdio";
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ switch0: ethernet-switch@30 {
+ compatible = "brcm,bcm53125";
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ ports {
+ port0@0 {
+ reg = <0>;
+ label = "lan1";
+ };
+
+ port1@1 {
+ reg = <1>;
+ label = "lan2";
+ };
+
+ port5@5 {
+ reg = <5>;
+ label = "cable-modem";
+ fixed-link {
+ speed = <1000>;
+ duplex-full;
+ };
+ phy-mode = "rgmii-txid";
+ };
+
+ port8@8 {
+ reg = <8>;
+ label = "cpu";
+ fixed-link {
+ speed = <1000>;
+ duplex-full;
+ };
+ phy-mode = "rgmii-txid";
+ ethernet = <&eth0>;
+ };
+ };
+ };
+ };
