This adds support for Flexible PPS output (which is equivalent to per_out output of PTP subsystem). Tested using an oscilloscope and the following commands: 1) Start PTP4L: # ptp4l -A -4 -H -m -i eth0 & 2) Set Flexible PPS frequency: # echo <idx> <ts> <tns> <ps> <pns> > /sys/class/ptp/ptpX/period Where, ts/tns is start time and ps/pns is period time, and ptpX is ptp of eth0.
