Hi Dror
I'm surprised you are doing SGMII between ports 10. They are 10G
capable.
gem0: {
fixed-link {
speed = <1000>;
full-duplex;
};
phy0: phy@0: {
reg = <0>;
};
switch0: switch@1c: {
compatible = "marvell,mv88e6190";
reg = <0x1c>;
ports {
#address-cells = <1>;
#size-cells = <0>;
port@0 {
reg = <0>;
label = "cpu";
fixed-link {
speed = <1000>;
full-duplex;
};
port@1 {
reg = <1>;
label = "lan0";
};
port@2 {
reg = <2>;
label = "lan1";
};
...
switch0port10: port@10 {
reg = <10>;
label = "dsa";
link = <&switch1port10>;
phy-mode = "sgmii";
fixed-link {
speed = <1000>;
full-duplex;
};
};
};
};
switch1: switch@1d: {
compatible = "marvell,mv88e6190";
reg = <0x1d>;
ports {
#address-cells = <1>;
#size-cells = <0>;
port@0 {
reg = <0>;
label = "lan9";
};
port@1 {
reg = <1>;
label = "lan10";
};
port@2 {
reg = <2>;
label = "lan11";
};
...
switch1port10: port@10 {
reg = <10>;
label = "dsa";
link = <&switch0port10>;
phy-mode = "sgmii";
fixed-link {
speed = <1000>;
full-duplex;
};
};
};
};
};
gem1: {
phy-handle = <phy0>;
};
It looks like you have at last one issue to solve in the macb driver.
If you have a fixed-phy, it does an mdiobus_register. This means it is
going to ignore all the other device tree properties. You need it to
do an of_mdiobus_register().
