n.b. sorry if you receive this twice - ThunderBird seems very crashy lately!
I'm trying to update my MPC8379 board from 3.0 to 3.3. I have
this setup in my device tree:
mdio@24520 {
#address-cells = <1>;
#size-cells = <0>;
compatible = "fsl,gianfar-mdio";
reg = <0x24520 0x20>;
phy0: ethernet-phy@0 {
interrupt-parent = <&ipic>;
interrupts = <17 0x8>;
reg = <0x01>;
device_type = "ethernet-phy";
};
phy1: ethernet-phy@1 {
interrupt-parent = <&ipic>;
interrupts = <18 0x8>;
reg = <0x00>;
device_type = "ethernet-phy";
};
};
enet0: ethernet@24000 {
cell-index = <0>;
device_type = "network";
model = "TSEC";
compatible = "gianfar";
reg = <0x24000 0x1000>;
local-mac-address = [ 00 08 e5 11 32 33 ];
interrupts = <32 0x8 33 0x8 34 0x8>;
interrupt-parent = <&ipic>;
phy-handle = <&phy0>;
linux,network-index = <0>;
};
enet1: ethernet@25000 {
cell-index = <1>;
device_type = "network";
model = "TSEC";
compatible = "gianfar";
reg = <0x25000 0x1000>;
local-mac-address = [ 00 08 e5 11 32 34 ];
interrupts = <35 0x8 36 0x8 37 0x8>;
interrupt-parent = <&ipic>;
phy-handle = <&phy1>;
linux,network-index = <1>;
};
On 3.0, this works just fine. When I boot the same setup on 3.3,
I get this error:
fsl-pq_mdio: probe of ff024520.mdio failed with error -16
Is there something I need to change in my DTS file to make this work?
Something else I might be missing?
I think I found it - I need to add a TBI node to my PHY setup.
It's working now.
