Daniel P. Carvalho c21d96eb68 arch/arm/stm32: deliver direct hardware counter timestamps for PTP.
The MAC hardware counter is the PTP clock reference. Delivering its
raw timestamp directly (instead of synthesizing one against
CLOCK_REALTIME, which starts at an arbitrary boot-time phase) lets the
PTP daemon close the feedback loop and phase-lock the MAC counter -
and therefore the physical PPS output - to the master.
