Linux version 5.10.65-00022-g0f2782ebe1fa-dirty
in 5.4 i was able to have in my dts file for ethernet:
&mac {
slaves = <1>;
pinctrl-names = "default", "sleep";
pinctrl-0 = <&mii_1_pins_default>;
pinctrl-1 = <&mii_1_pins_sleep>;
status = "okay";
};
&davinci_mdio {
pinctrl-names = "default", "sleep";
pinctrl-0 = <&mdio_1_pins_default>;
pinctrl-1 = <&mdio_1_pins_sleep>;
status = "okay";
};
&cpsw_emac0 {
phy_id = <&davinci_mdio>, <1>;
phy-mode = "mii";
};
we have a TI phy DP83848 connected to MII1 1 in MII mode 10/100
and that doesn't seem to be allowed anymore. so i followed up with some changes and it seems no matter what i cannot get it to work. some things i have tried:
&mac_sw {
pinctrl-names = "default";
pinctrl-0 = <&mii_1_pins_default>;
status = "okay";
};
&davinci_mdio_sw {
pinctrl-names = "default";
pinctrl-0 = <&mdio_1_pins_default>;
ethphy0: ethernet-phy@0 {
reg = <0>;
};
ethphy1: ethernet-phy@1 {
reg = <1>;
};
};
&cpsw_port1 {
phy-handle = <ðphy0>;
phy-mode = "mii";
ti,dual-emac-pvid = <1>;
};
&cpsw_port2 {
phy-handle = <ðphy1>;
phy-mode = "mii";
ti,dual-emac-pvid = <2>;
};
that didn't work
&mac_sw {
pinctrl-names = "default", "sleep";
pinctrl-0 = <&mii_1_pins_default>;
pinctrl-1 = <&mii_1_pins_sleep>;
status = "okay";
};
&davinci_mdio_sw {
pinctrl-names = "default", "sleep";
pinctrl-0 = <&mdio_1_pins_default>;
pinctrl-1 = <&mdio_1_pins_sleep>;
ethphy1: ethernet-phy@1 {
reg = <1>;
};
};
&cpsw_port1 {
phy-handle = <ðphy1>;
phy-mode = "rmii";
ti,dual-emac-pvid = <1>;
};
&cpsw_port2 {
status = "disabled";
};
that didn't work
&mac_sw {
slaves = <1>;
pinctrl-names = "default", "sleep";
pinctrl-0 = <&mii_1_pins_default>;
pinctrl-1 = <&mii_1_pins_sleep>;
status = "okay";
};
&davinci_mdio_sw {
pinctrl-names = "default", "sleep";
pinctrl-0 = <&mdio_1_pins_default>;
pinctrl-1 = <&mdio_1_pins_sleep>;
status = "okay";
};
&cpsw_port1 {
phy_id = <&davinci_mdio_sw>, <1>;
phy-mode = "mii";
};
that didn't work
every time when my board boots i get seemingly no error message about networks and when i do ifconfig i get
root@am437x-evm:~# ifconfig
lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0

i would really like to know the magic comination to make this work again
