As you have pointed out, for SyncE selection, the user must be able to manu= ally select a pin state to enable recovery of signal from particular port. In "ice" case there are 2 pins for network PHY clock signal recovery, and b= oth are parent pins (MUX-type). There are also 4 pins assigned to netdevs (one = per port). Thus passing a signal from PHY to the pin is done through the MUX-pi= n, by selecting proper state on pin-parent pair (where parent pins is highest = prio pin on dpll). Thank you! Arkadiusz
