      * Using a Telecom Time Synchronous Clock (T-TSC) configuration causes the ts2phc metrics to report "unlocked" instead of "locked". As a result, you might encounter inaccurate Precision Time Protocol (PTP) clock state reporting. To work around this issue, remove the `ts2phc` metric. OCPBUGS-63158

      Description of problem:

      With TR / T-TSC configuration only ts2phc metrics reports unlocked, ptp4l metric is reported.

      Version-Release number of selected component (if applicable):

          ptp-operator.v4.20.0-202510141524

      How reproducible:

      100%

      Steps to Reproduce:

          1.Deploy PTP with T-TSC / TR configuration

      Actual results:

          # TYPE openshift_ptp_clock_state gauge
openshift_ptp_clock_state{iface="CLOCK_REALTIME",node="helix65.lab.eng.rdu2.redhat.com",process="phc2sys"} 1
openshift_ptp_clock_state{iface="ens1fx",node="helix65.lab.eng.rdu2.redhat.com",process="dpll"} 1
openshift_ptp_clock_state{iface="ens1fx",node="helix65.lab.eng.rdu2.redhat.com",process="ts2phc"} 1
openshift_ptp_clock_state{iface="ens2fx",node="helix65.lab.eng.rdu2.redhat.com",process="T-BC"} 1
openshift_ptp_clock_state{iface="ens2fx",node="helix65.lab.eng.rdu2.redhat.com",process="dpll"} 1
openshift_ptp_clock_state{iface="ens2fx",node="helix65.lab.eng.rdu2.redhat.com",process="ptp4l"} 1
openshift_ptp_clock_state{iface="ens2fx",node="helix65.lab.eng.rdu2.redhat.com",process="ts2phc"} 0

      Expected results:

          TBD; removal of ts2phc metric and ptp4l?

      Additional info:

      With T-BC / TR & TT Configuration
