setup PHY addresses KERNEL Flattened Device Tree

[Иван Арищенко]

Hello,

   I am working on custom board based on Beagle Bone Black. The board has a 

different PHY chip (DP83640). The PHY address is 31 (0x1f).

   I have a issue with ethernet support in Linux kernel (3.8.13  Flattened Device Tree).

 

[   52.892438] davinci_mdio 4a101000.mdio: davinci mdio revision 1.6

[   52.898851] davinci_mdio 4a101000.mdio: detected phy mask ffdfffff

[   52.972785] net eth0: phy 4a101000.mdio:01 not found on slave 1

The ethernet interface works in previous kernel (3.2.0)

I think the issue is wrong PHY address. I can not find a place in Linux kernel 3.8.13 source 

where i can set up PHY address; 

Could you please help me to find the place where i can set up PHY address?

Best Regards,

Ivan Arishchenko

why don't you just change <0> to <0x1f> and recompile the dts file?
