[PATCH 0/2] ice: ptp: fix E825 timer synchronization and locking

[Grzegorz Nitka <grzegorz.nitka@intel.com>]

These two fixes address E825 PTP synchronization issues in
ice_ptp_hw.c.

The first patch serializes PHY timer start against concurrent PTP
command paths by holding the global PTP semaphore while programming
TIMETUS registers and issuing INIT_INCVAL.

The second patch fixes semaphore access for E825 2xNAC configurations by
making ice_ptp_lock() and ice_ptp_unlock() use the primary NAC register
block, matching the rest of the primary-only PTP register access path.

Together, the series closes two locking gaps in E825 timer control: one
during PHY timer initialization and one in 2xNAC semaphore selection.

Grzegorz Nitka (2):
  ice: ptp: serialize E825 PHY timer start with PTP lock
  ice: ptp: use primary NAC semaphore on E825
