How to change the 1588 PTP reference clock to fpga_ptp_ref_clk in Cyclone V

Hi I am using FAMILY Cyclone V DEVICE 5CSEBA6U23I7 in my design and I an using linuxptp to tune the external PLL, in the first stemp I want to use the fpga_ptp_ref clock from FPGA side, I tried...

I figured out that we need to enable the signal from FPGA side to emac by setting 0xFFD08028 =0xD , by this Signals from FPGA fabric can potentially affect operation of the EMAC module

If you want to change the PTP refeernce clock then you need to set

0xFFD08028 =0xD

0xFFD08060 =0x36
