We are currently trying to change the eth2 pins to i2c pins but we cannot get ethernet working when we disable eth2 (fec2). I have tried moving the mdio node to the fec1 node, but I still can't get it to work. Any suggestions? Also, what does the @1 in ethernet-phy@1 mean?
I have the following in my device.dts
/* Disable the second ethernet port and remove the mdio for use in fec1 */
&fec2 {
status = "disabled";
/delete-node/ mdio;
};
/* Add mdio to the fec1 node */
&fec1 {
mdio {
#address-cells = <1>;
#size-cells = <0>;
ethphy0: ethernet-phy@1 {
compatible = "ethernet-phy-ieee802.3-c22";
micrel,rmii-reference-clock-select-25-mhz;
clocks = <&rmii_ref_clk>;
clock-names = "rmii-ref";
reg = <1>;
};
ethphy1: ethernet-phy@3 {
compatible = "ethernet-phy-ieee802.3-c22";
micrel,rmii-reference-clock-select-25-mhz;
clocks = <&rmii_ref_clk>;
clock-names = "rmii-ref";
reg = <3>;
};
};
};
