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/net/dsa/dsa.txt for a list of additional
|
||
|
|
required, optional properties and how the integrated switch subnodes must
|
||
|
|
be specified.
