using Ian's patch as is, I have the following in kirkwood.dtsi:

+
+               smi0: mdio at 72000 {
+                       compatible = "marvell,mdio-mv643xx";
+                       reg = <0x72000 0x4000>;
+                       interrupts = <46>;
+                       status = "disabled";
+               };
+
+               smi1: mdio at 76000 {
+                       compatible = "marvell,mdio-mv643xx";
+                       reg = <0x76000 0x4000>;
+                       interrupts = <47>;
+                       status = "disabled";
+               };
+
+               egiga0 {
+                       compatible = "marvell,mv643xx-eth";
+                       reg = <0x72000 0x4000>;
+                       mdio = <&smi0>;
+                       port_number = <0>;
+                       phy_addr = <0x80>;
+                       interrupts = <11>;
+                       clocks = <&gate_clk 0>;
+                       status = "disabled";
+               };
+
+               egiga1 {
+                       compatible = "marvell,mv643xx-eth";
+                       reg = <0x76000 0x4000>;
+                       mdio = <&smi1>;
+                       port_number = <1>;
+                       phy_addr = <0x81>;
+                       interrupts = <15>;
+                       clocks = <&gate_clk 19>;
+                       status = "disabled";
+               };

I'll see if I can get it working as is, then we can migrate to Thomas'
mdio bindings.

btw - it might be a shared smi, I haven't looked yet, and haven't
tested...

thx,

Jason.
