   2 ================================
   3
   4 Required 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
  17 If 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
  21 Else, 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
  27 Required 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
  34 See Documentation/devicetree/bindings/dsa/dsa.txt for a list of additional
  35 required, optional properties and how the integrated switch subnodes must
  36 be specified.
