I'm trying to port my MPC8379 board from 3.0 to 3.3.  In 3.0, I have
this setup in my device tree:

		mdio@24520 {
			#address-cells = <1>;
			#size-cells = <0>;
			compatible = "fsl,gianfar-mdio";
			reg = <0x24520 0x20>;

			phy0: ethernet-phy@0 {
				interrupt-parent = <&ipic>;
				interrupts = <17 0x8>;
				reg = <0x01>;
				device_type = "ethernet-phy";
			};
			phy1: ethernet-phy@1 {
				interrupt-parent = <&ipic>;
				interrupts = <18 0x8>;
				reg = <0x00>;
				device_type = "ethernet-phy";
			};
		};

		enet0: ethernet@24000 {
			cell-index = <0>;
			device_type = "network";
			model = "TSEC";
			compatible = "gianfar";
			reg = <0x24000 0x1000>;
			local-mac-address = [ 00 08 e5 11 32 33 ];
			interrupts = <32 0x8 33 0x8 34 0x8>;
			interrupt-parent = <&ipic>;
			phy-handle = <&phy0>;
			linux,network-index = <0>;
		};

		enet1: ethernet@25000 {
			cell-index = <1>;
			device_type = "network";
			model = "TSEC";
			compatible = "gianfar";
			reg = <0x25000 0x1000>;
			local-mac-address = [ 00 08 e5 11 32 34 ];
			interrupts = <35 0x8 36 0x8 37 0x8>;
			interrupt-parent = <&ipic>;
			phy-handle = <&phy1>;
			linux,network-index = <1>;
		};

On 3.0, this works just fine.  When I boot the same setup on 3.3,
I get this error:
   fsl-pq_mdio: probe of ff024520.mdio failed with error -16

Is there something I need to change in my DTS file to make this work?
Something else I might be missing?

Thanks
