+Mediatek MT7530 Ethernet switch
+================================
+
+Required properties:
+
+- compatible: Must be compatible = "mediatek,mt7530";
+- #address-cells: Must be 1
+- #size-cells: Must be 0
+- mediatek,ethsys: Phandle to the syscon node that handles the reset.
+- mediatek,ethernet: Phandle to the syscon node that Mediatek ethernet driver
+ provides that handles the TRGMII setup used by the switch.
+ See
+ Documentation/devicetree/bindings/net/mediatek-net.txt for the detailed
+ setup on mediatek ethernet.
+- mediatek,mcm: String, should be "enabled" or "disabled" to indicate 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.
+- mediatek,reset-pin: Phandle to the pinctrl node used for the reset. Which
+ must be required if the property mediatek,mcm of specified as
+ "disabled". See
+ Documentation/devicetree/bindings/pinctrl/pinctrl-mt65xx.txt for
+ the mediatek pintcrl setting for the details.
+
+Each port children node within ports container must have the following
+mandatory properties:
+- reg : Port address described must be 6 for CPU port
+ and from 0 to 5 for user ports.
+
+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>;
+
+ mediatek,ethsys = <&ethsys>;
+ mediatek,ethernet = <&eth>;
+ mediatek,mcm = "enabled";
+ core-supply = <&mt6323_vpa_reg>;
+ io-supply = <&mt6323_vemc3v3_reg>;
+
+ 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 = <&eth>;
+ phy-mode = "trgmii";
+ fixed-link {
+ speed = <1000>;
+ full-duplex;
+ };
+ };
+ };
+ };
+ };
