i210: How programmatically use the SDP signals to correct the offsets for 4 i210 devices at boot time?

I have 4 i210 device on one board. I want to make sure that the four of them has the exact timer offset (will be used in 1588 setup).

Because they may have different initialization time they may end up with different time offset. I want to use the SDP at boot time to set the four of then on the same time offset.

Thank you

Thank you Carols for the fast response. I think I need to know exactly what I need to do in order to to get the four of the i210 to have the exact same time. Is it something I need to make on the kernel driver code or I can use the driver interface to accomplish it? The documentation you pointed me to have good info, but I am still not clear how I can get the four of the i210 to have the same exact time after initialization.

Basically a way to correct for offset at initialization timer.

 

Thank you
