Parallella Community

Hi All,
I created an IP core which has GMII interface and IP packets are used to control it and send/receive data.
I make a redirection of all necessary pins related to Ethernet 1 to EMIO but I don't know how to tell Ethernet controller to use Tx/Rx clocks from EMIO.
I suppose I need to add something to the device tree. I found solution how to extract device tree from Parallela OS image to the plain text.

Does anybody know what should be added to the device tree so Ethernet 1 starts getting clocks from EMIO?
