Trying to make the Fixed PHY work under my 832x based board on current
linus tree without success. Earlier kernels with custom PHY code for
ucc_geth work without any special tricks.
If I enable the FIXED_MII_100_FDX option I get:
ls bus/mdio_bus/devices/
fixed@100:1@
but ucc_geth wants its PHYs under
ls -l bus/of_platform/devices/*phy*

-> ../../../devices/e0100000.qe/e0102320.mdio/fixed-phy.2/ These are
3 PHYs I just added in the DTS tree:
mdio@2320 {
#address-cells = <1>;
#size-cells = <0>;
reg = <2320 18>;
device_type = "mdio";
compatible = "ucc_geth_phy";
phy1: ethernet-phy@18 {
linux,phandle = <212000>;
reg = <18>; // 24
device_type = "ethernet-phy";
interface = <3>; //ENET_100_MII
};
phy2: fixed-phy@64 {
linux,phandle = <212001>;
reg = <d#100>;
device_type = "ethernet-phy";
};
phy3: ethernet-phy@19 {
linux,phandle = <212002>;
interrupt-parent = <700>;
interrupts = <12 2>;
reg = <19>; // 25
device_type = "ethernet-phy";
interface = <3>; //ENET_100_MII
};
};
How do I add a fixed PHY so that ucc_geth finds it?well I guess ucc stuff follows gianfar trend in mdio bus specification for the phy. So, it would look like %d:%d or something like that. Can you please dump the whole dts here?
