octeontx2-pf: Enable PTP PPS output support
PTP block supports generating PPS output signal on GPIO pin. This patch
adds the support in the PTP PHC driver using standard periodic output
interface.
User can enable/disable/configure PPS by writing to the below sysfs entry
echo perout.index start.sec start.nsec period.sec period.nsec >
/sys/class/ptp/ptp0/period
Example to generate 50% duty cycle PPS signal:
echo 0 0 0 0 500000000 > /sys/class/ptp/ptp0/period
