Subject: [PATCH net-next 0/5] net: lan966x: Add support for PTP programmable pins

Lan966x has 8 PTP programmable pins. The last pin is hardcoded to be used
by PHC0 and all the rest are shareable between the PHCs. The PTP pins can
implement both extts and perout functions.

Horatiu Vultur (5):
  dt-bindings: net: lan966x: Extend with the ptp external interrupt.
  net: lan966x: Change the PTP pin used to read/write the PHC.
  net: lan966x: Add registers used to configure the PTP pin
  net: lan966x: Add support for PTP_PF_PEROUT
  net: lan966x: Add support for PTP_PF_EXTTS
