+Mediatek MT7530 Ethernet switch
+================================
+
+Required properties:
+
+- compatible: Must be compatible = "mediatek,mt7530";
+- #address-cells: Must be 1.
+- #size-cells: Must be 0.
+- mediatek,mcm: Boolean; if defined, indicates that either MT7530 is the part
+ on multi-chip module belong to MT7623A has or the remotely standalone
+ chip as the function MT7623N reference board provided for.
+- core-supply: Phandle to the regulator node necessary for the core power.
+- io-supply: Phandle to the regulator node necessary for the I/O power.
+ See Documentation/devicetree/bindings/regulator/mt6323-regulator.txt
+ for details for the regulator setup on these boards.
+
+If the property mediatek,mcm isn't defined, following property is required
+
+- reset-gpios: Should be a gpio specifier for a reset line.
+
+Else, following properties are required
+
+- resets : Phandle pointing to the system reset controller with
+ line index for the ethsys.
+- reset-names : Should be set to "mcm".
+
+Required properties for the child nodes within ports container:
+
+- reg: Port address described must be 6 for CPU port and from 0 to 5 for
+ user ports.
+- phy-mode: String, must be either "trgmii" or "rgmii" for port labeled
+ "cpu".
+
+See Documentation/devicetree/bindings/dsa/dsa.txt for a list of additional
+required, optional properties and how the integrated switch subnodes must
+be specified.
+
+Example:
+
+ &mdio0 {
+ switch@0 {
+ compatible = "mediatek,mt7530";
+ #address-cells = <1>;
+ #size-cells = <0>;
+ reg = <0>;
+
+ core-supply = <&mt6323_vpa_reg>;
+ io-supply = <&mt6323_vemc3v3_reg>;
+ reset-gpios = <&pio 33 0>;
+
+ ports {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ reg = <0>;
+ port@0 {
+ reg = <0>;
+ label = "lan0";
+ };
+
+ port@1 {
+ reg = <1>;
+ label = "lan1";
+ };
+
+ port@2 {
+ reg = <2>;
+ label = "lan2";
+ };
+
+ port@3 {
+ reg = <3>;
+ label = "lan3";
+ };
+
+ port@4 {
+ reg = <4>;
+ label = "wan";
+ };
+
+ port@6 {
+ reg = <6>;
+ label = "cpu";
+ ethernet = <&gmac0>;
+ phy-mode = "trgmii";
+ fixed-link {
+ speed = <1000>;
+ full-duplex;
+ };
+ };
+ };
+ };
+ };
