1Mediatek MT7530 Ethernet switch
2================================
3
4Required properties:
5
6- compatible: Must be compatible = "mediatek,mt7530";
7- #address-cells: Must be 1.
8- #size-cells: Must be 0.
9- mediatek,mcm: Boolean; if defined, indicates that either MT7530 is the part
10	on multi-chip module belong to MT7623A has or the remotely standalone
11	chip as the function MT7623N reference board provided for.
12- core-supply: Phandle to the regulator node necessary for the core power.
13- io-supply: Phandle to the regulator node necessary for the I/O power.
14	See Documentation/devicetree/bindings/regulator/mt6323-regulator.txt
15	for details for the regulator setup on these boards.
16
17If the property mediatek,mcm isn't defined, following property is required
18
19- reset-gpios: Should be a gpio specifier for a reset line.
20
21Else, following properties are required
22
23- resets : Phandle pointing to the system reset controller with
24	line index for the ethsys.
25- reset-names : Should be set to "mcm".
26
27Required properties for the child nodes within ports container:
28
29- reg: Port address described must be 6 for CPU port and from 0 to 5 for
30	user ports.
31- phy-mode: String, must be either "trgmii" or "rgmii" for port labeled
32	 "cpu".
33
34See Documentation/devicetree/bindings/net/dsa/dsa.txt for a list of additional
35required, optional properties and how the integrated switch subnodes must
36be specified.
