The default behaviour is to keep PTP TSC sync logic enabled. The default behaviour is to keep PTP TSC sync logic enabled.
- ptp_tsc_sync_trig_interval: Defines interval(in terms of PPS edge count) at which PTP-TSC sync
alignment should be triggered eg: if value 3 is provided, then an attempt is
made to sync TSC with PTP(if not synchronized) on every 3rd PPS edge.
Supported min & max values are 1 & 8 respectively and by default, value
of 1 is used to trigger TSC sync on every PPS edge.
