Dear Hauke,
Thanks!!
thank you for pointing me out at the teleko-speedport source code! I will compare and look at this very soon today.
So, with your help guys, I started from the vendor code in here:
http://osp.avm.de/fritzbox/fritzbox-3272/source-files-FRITZ.Box_3272-06.20.tar.gz
And started by writing an "arx300.dtsi" ifle - comparing with Bjorn's work, who he nicely provided, pointing me at it.
And pointing out I was using the wrong ebu address.
target/linux/lantiq/files/arch/mips/boot/dts/arx300.dtsi looks like:

Hi there!
So I am trying to get ethernet working on this AR10 device.
It has 3 GPHYs:
gphy0: gphy@20 {
compatible = "lantiq,xrx300-gphy";
reg = <0x20 0x4>;
resets = <&reset0 31 30>, <&reset1 7 7>;
reset-names = "gphy", "gphy2";
};
gphy1: gphy@58 {
compatible = "lantiq,xrx300-gphy";
reg = <0x58 0x4>;
resets = <&reset0 29 28>, <&reset1 6 6>;
reset-names = "gphy", "gphy2";
};
gphy2: gphy@ac {
compatible = "lantiq,xrx300-gphy";
reg = <0xac 0x4>;
resets = <&reset0 27 26>, <&reset1 5 5>;
reset-names = "gphy", "gphy2";
};
And firmware load addresses for GPHYs are correct as per the vendor code:
#define IFX_RCU_GPHY0_FW_ADDR ((volatile u32*)(IFX_RCU + 0x0020))
#define IFX_RCU_GPHY1_FW_ADDR ((volatile u32*)(IFX_RCU + 0x0058))
#define IFX_RCU_GPHY2_FW_ADDR ((volatile u32*)(IFX_RCU + 0x00AC))
But driver was failing to initialize due to missing clock gates.
In sysctrl.c, we have:
clkdev_add_pmu("1f203020.gphy", NULL, 1, 0, PMU_GPHY); // OK for GPHY0
clkdev_add_pmu("1f203068.gphy", NULL, 1, 0, PMU_GPHY); //problem for GPHY1
And GPHY2?
Attaching complete AR10 DTS I obtained collecting informations from various sources.
I would ask you if you could kindly help me pointing out mistakes,.
I am sure I am accumulating a fair amount of useless stuff in this file.

With the upstream DSA driver you should be able to define this mostly in device tree. GMAC0: RGMII port GMAC2: GPHY0 (GMII) GMAC3: GPHY0 (MII) GMAC4: GPHY1 (GMII) GMAC5: GPHY1 (MII) or RGMII port GMAC1: GPHY2 (GMII) Hauke

Yeah - infact I did this change, resulting in the first two GPHYs initializing, while the one at "1f2030ac.gphy" had more issues - and kernel oopsed. So I was thinking the logic was wrong. I'll look at it again. Enrico
