I'm porting Linux 2.6.32.6 to our MPC8247 based board. We use SCC3 and
SCC4 as ethernet port. These two ports are connect with LXT905 PHY
chip.
I'm now using fs_enet driver, how should I config the scc port in dtc
file. I copied from mgcoge.dts file, and my dtc file of scc enet is
follows:
eth2: ether...@11a40 {
device_type = "network";
compatible = "fsl,mpc8247-scc-enet",
"fsl,cpm2-scc-enet";
reg = <0x11a40 0x20 0x8200 0x100 0x11390 0x1>;
local-mac-address = [ 00 00 00 00 00 00 ]; /* filled
by U-Boot */
interrupts = <42 8>;
interrupt-parent = <&PIC>;
linux,network-index = <0x2>;
fsl,cpm-command = <0x8c00000>;
fixed-link = < 0 0 10 0 0 >;
};
But i does not working. Linux says that PHY 0:00 is not found. I dive
into the code, and that's according to the fixed-link property.
I'm wondering how to support scc-enet in my situation.
Do you really want fixed-link, or does the board have a working MDIO
interface? If the latter, you need a phy-handle property instead,
pointing to a PHY node under an MDIO bus node that represents how MDIO
is wired on your board.
