Subject: [PATCH net-next 0/3] ptp: add pulse signal loopback support for debugging

Some PTP devices support looping back the periodic pulse signal for
debugging, so add the generic debugfs interfaces to the ptp_clock
driver. The first two patch are separated from the previous patch
set [1]. The third patch is new added.

[1]: https://lore.kernel.org/imx/20250827063332.1217664-1-wei.fang@nxp.com/ #patch 3 and 9

Wei Fang (3):
  ptp: add debugfs interfaces to loop back the periodic output signal
  ptp: netc: add the periodic output signal loopback support
  ptp: qoriq: covert to use generic interfaces to set loopback mode
