Reference clock fmcomms3

Hi everyone,


I am working on the FMcomms3 (zedboard) and I want to use a 10MHZ reference clock.

I have already removed the crystal and put a capacitor instead, as advised on the wiki.analog website. 


I read everywhere that the clock value should be changed manually in linux/arch/arm/boot/dts/adi-fmcomms2.dtsi. 

My question is : would it be the same to manually edit, on the fmcomms3 sd card, in /media/analog/BOOT/zynq-zed-adv7511-ad9361-fmcomms2-3, the devicetree.dts file ? Because I can't find these lines :

The only clock referring lines I have are at the end of the file and are : 


clocks {
clock@0 {
#clock-cells = <0>;
compatible = "fixed-clock";
clock-frequency = <40000000>;
clock-output-names = "ad9361_ext_refclk";



clock@1 {






Thank you in advance and have great day !
