We have Ethernet connected on RGMII Interface.
modified the dts but still the drivers are not able to detect the interface.

Also I am attaching the menu configuration where we have enabled the Micrel net phy drivers, Please find the kernel config and its screenshots attached.
I have a queries:
Where to setup this address net eth0: CPSW phy found : PHY_ID is : 0x221611 and PHY_MASK in dts?
Please find the DTS attached.hs_ethernet_dts.zip
