* Marvell MDIO Ethernet Controller interface
|
||||
|
||||
The Ethernet controllers of the Marvel Kirkwood, Dove, Orion5x,
|
||||
MV78xx0, Armada 370, Armada XP, Armada 7k and Armada 8k have an
|
||||
identical unit that provides an interface with the MDIO bus.
|
||||
Additionally, Armada 7k and Armada 8k has a second unit which
|
||||
provides an interface with the xMDIO bus. This driver handles
|
||||
these interfaces.
|
||||
|
||||
Required properties:
|
||||
- compatible: "marvell,orion-mdio" or "marvell,xmdio"
|
||||
- reg: address and length of the MDIO registers. When an interrupt is
|
||||
not present, the length is the size of the SMI register (4 bytes)
|
||||
otherwise it must be 0x84 bytes to cover the interrupt control
|
||||
registers.
|
||||
|
||||
Optional properties:
|
||||
- interrupts: interrupt line number for the SMI error/done interrupt
|
||||
- clocks: phandle for up to four required clocks for the MDIO instance
|
||||
|
||||
The child nodes of the MDIO driver are the individual PHY devices
|
||||
connected to this MDIO bus. They must have a "reg" property given the
|
||||
PHY address on the MDIO bus.
|
||||
|
||||
Example at the SoC level without an interrupt property:
|
||||
|
||||
mdio {
|
||||
#address-cells = <1>;
|
||||
#size-cells = <0>;
|
||||
compatible = "marvell,orion-mdio";
|
||||
reg = <0xd0072004 0x4>;
|
||||
};
|
||||
|
||||
Example with an interrupt property:
|
||||
|
||||
mdio {
|
||||
#address-cells = <1>;
|
||||
#size-cells = <0>;
|
||||
compatible = "marvell,orion-mdio";
|
||||
reg = <0xd0072004 0x84>;
|
||||
interrupts = <30>;
|
||||
};
|
||||
|
||||
And at the board level:
|
||||
|
||||
mdio {
|
||||
phy0: ethernet-phy@0 {
|
||||
reg = <0>;
|
||||
};
|
||||
|
||||
phy1: ethernet-phy@1 {
|
||||
reg = <1>;
|
||||
};
|
||||
}
