As you understand, I prefer not to change the driver.
Is there a way for me to bypass this issue?
Can I use other property than 'fixed-link'?
>Please include the full panic details. The stack trace can be very useful.
Please, see below:

My quick look at the driver makes me think you are going to have to
change it. But the changes can be mainlined, if done correctly.
I think it is time you rolled up your sleeves and start really
debugging this yourselves, and make the needed changes.

I think this is a problem with the macb driver. To me, it looks like
you are going to have to make some changes to the driver to make this
work. Normally the MDIO bus children are placed within a container
node, often called 'mdio-bus' or simply 'mdio'. See for example
Documentation/devicetree/bindings/net/fsl-fec.txt. The macb driver
does not do this. It passed the main DT node of the device to
of_mdiobus_register(). It then walks all the children assuming they
devices on the MDIO bus. But the first child it finds is the
'fixed-link'. This is not supposed to be a child of the bus, which is
why it goes wrong.

The link parameters look correct. It is a pointer to the switches port
in the DSA link.
But i spotted a real problem. See bellow.

This is correct. The product number is contains the revision. You have
revision 0.

Hello Andrew,
You deserve a big thank you for your solution to our device-tree - the linux bootup log looks a lot better and It made a big progress for us.
Though we still have some issues...
1. Attached are 2 log files that are the result of your suggested dts:
1st is your device-tree as is : results in kernel panic. Its probably caused by the "link" parameter.
2nd is your device tree with gem0 port's10 "link" parameter commented on both switches. It results in good kernel but still the devices are not properly detected. Maybe its related to the comment you wrote below about the fixed PHY driver issue that prevents the driver to complete his phy address scan (stops at phy addr 1...).
2. The switch's product number should be 0x0a1 but instead its 0xa10 (is it just a high-low byte thing?)
3. The stand-alone phy (gem1) is not detected properly. It should be device id mv88e1510.
Please advise how to continue from here.
Regards,
Michael Alayev

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().

Hi Dror
I'm surprised you are doing SGMII between ports 10. They are 10G
capable.

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().
