I've had the smae problem, and it's not just a multiplexing problem, but
also in the dreamplug.dts file send by Matthieu, he uses the wrong
address for mdio1 and enet1: 74000 instead of 76000 (although the
comments suggest he suspected the problem already :-) )
The two necessary bits in corected version make mge1 work:
mdio1: mdio@76000 { /* 76000? */
device_type = "mdio";
compatible = "mrvl,mdio";
reg = <76000 20>;
#address-cells = <1>;
#size-cells = <0>;
phy1: ethernet-phy@0 {
reg = <1>;
device_type = "ethernet-phy";
};
};
enet1: ethernet@76000 { /* 76000? */
#address-cells = <1>;
#size-cells = <1>;
model = "V2";
compatible = "mrvl,ge";
reg = <0x76000 0x2000>;
ranges = <0x0 0x74000 0x2000>;
local-mac-address = [ 00 00 00 00 00 00 ];
interrupts = <16 17 18 15 47>;
interrupt-parent = <&PIC>;
phy-handle = <&phy1>;
};
Additionally, if you need the pins multiplexed differently, there is an
openrd-cl.dts found in this thread, (included in sdio_patch.txt), which
also adds sdio support to HEAD. I've applied the patch without problems
to 9-BETA3.
There are two issues though: the included openrd-cl.dts adds pci support
which causes a kernel panic, and the sdio driver actually doesn't seem
to work. Didn't have enough time to investigate that yet.
