Fixed Phy Support on Kernel 4.1-ltsi_16.04.01_pr

Hello everybody,

I have fixed phy support implemented in kernel 3.10-ltsi based on this patch

I would like to move to kernel 4.1-ltsi.
But it looks like the phy thing has been moved out from arch/arm/mach-socfpga/socfpga.c

Could anyone help me here how to do fixed phy in new 4.1-ltsi kernel?
Can it be now set only in device tree somehow, or is some code change needed?

Thank you.
