Hi Rodolfo
Humm, that needs testing. There are two used combinations you need to
test:
No MDIO node in device tree, e.g.
arch/arm/boot/dts/kirkwood-dir665.dts
MDIO node in device tree, e.g:
arch/arm/boot/dts/vf610-zii-dev-rev-b.dts
There is a third combination which will appear soon. There is only the
external mdio bus in device tree:
port@9 {
reg = <9>;
label = "eth_cu_1000_2";
phy-handle = <&phy9>;
phy-mode = "sgmii";
managed = "in-band-status";
};
};
mdio1 {
compatible = "marvell,mv88e6xxx-mdio-external";
#address-cells = <1>;
#size-cells = <0>;
phy9: phy9@0 {
compatible =
"ethernet-phy-ieee802.3-c45";
pinctrl-0 = <&pinctrl_gpio_phy9>;
pinctrl-names = "default";
interrupt-parent = <&gpio2>;
interrupts = <30 IRQ_TYPE_LEVEL_LOW>;
reg = <0>;
};
};
Here port 9 uses the external MDIO bus and all the other ports
implicitly make use of the internal MDIO bus.
