|
+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 {
|
|

|
|
+ reg = <0>;

|
+ io-supply = <&mt6323_vemc3v3_reg>;
|
|
+ reset-gpios = <&pio 33 0>;
|
|

|
|
+ ports {
|
