+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,bcm5389"
+ "brcm,bcm5397"
+ "brcm,bcm5398"
+
+ For the BCM11360 SoC, must be:
+ "brcm,bcm11360-srab" and the mandatory "brcm,cygnus-srab" string
+
+ 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 BCM5831X/BCM1140x SoCs with an integrated switch, must be one of:
+ "brcm,bcm11404-srab"
+ "brcm,bcm11407-srab"
+ "brcm,bcm11409-srab"
+ "brcm,bcm58310-srab"
+ "brcm,bcm58311-srab"
+ "brcm,bcm58313-srab" and the mandatory "brcm,omega-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"
+
+Required properties for BCM585xx/586xx/88312 SoCs:
+
+ - reg: a total of 3 register base addresses, the first one must be the
+ Switch Register Access block base, the second is the port 5/4 mux
+ configuration register and the third one is the SGMII configuration
+ and status register base address.
+
+ - interrupts: a total of 13 interrupts must be specified, in the following
+ order: port 0-5, 7-8 link status change, then the integrated PHY interrupt,
+ then the timestamping interrupt and the sleep timer interrupts for ports
+ 5,7,8.
+
+Optional properties for BCM585xx/586xx/88312 SoCs:
+
+ - reg-names: a total of 3 names matching the 3 base register address, must
+ be in the following order:
+ "srab"
+ "mux_config"
+ "sgmii_config"
+
+ - interrupt-names: a total of 13 names matching the 13 interrupts specified
+ must be in the following order:
+ "link_state_p0"
+ "link_state_p1"
+ "link_state_p2"
+ "link_state_p3"
+ "link_state_p4"
+ "link_state_p5"

+ "link_state_p8"
+ "phy"
+ "ts"
+ "imp_sleep_timer_p5"
+ "imp_sleep_timer_p7"
+ "imp_sleep_timer_p8"
+
+See Documentation/devicetree/bindings/net/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>;
+ full-duplex;
+ };
+ };
+
+ mdio0: mdio@10000000 {
+ compatible = "brcm,unimac-mdio";
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ switch0: ethernet-switch@1e {
+ compatible = "brcm,bcm53125";
+ reg = <30>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ ports {
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ port0@0 {
+ reg = <0>;
+ label = "lan1";
+ };
+
+ port1@1 {
+ reg = <1>;
+ label = "lan2";
+ };
+
+ port5@5 {
+ reg = <5>;
+ label = "cable-modem";
+ fixed-link {
+ speed = <1000>;
+ full-duplex;
+ };
+ phy-mode = "rgmii-txid";
+ };
+
+ port8@8 {
+ reg = <8>;
+ label = "cpu";
+ fixed-link {
+ speed = <1000>;
+ full-duplex;
+ };
+ phy-mode = "rgmii-txid";
+ ethernet = <&eth0>;
+ };
+ };
