We've been using the patches from Ian Molton for the mv643xx driver
that make it use the more standard, separately described MDIO
bus..
Please consider not copying the unsual 'phy-addr' binding
for the new driver.
What we are used to seeing for ethernet+mdio is more like:
smi0: mdio@72000 {
device_type = "mdio";
compatible = "marvell,mdio-mv643xx";
reg = <0x72000 0x4000>;
interrupts = <46>;
tx_csum_limit = <1600>;
#address-cells = <1>;
#size-cells = <0>;
PHY1: ethernet-phy@1 {
reg = <1>;
device_type = "ethernet-phy";
phy-id = <0x01410e90>;
};
};
egiga0 {
device_type = "network";
compatible = "marvell,mv643xx-eth";
reg = <0x72000 0x4000>;
mdio = <&smi0>;
port_number = <0>;
phy-handle = <&PHY1>;
interrupts = <11>;
};
};
Where the MDIO bus is explicit, the PHY, its address and parameters
are explicit - the PHY has an of_node pointer - and phy-handle is used
to connect them.
I'm not sure having the MDIO bus as a distinct top level item is
great, considering how the registers overlap.. It might be better
to put it under the egiga0 block? But that is a minor nit :)
Regards,
Jason
