If the DWMAC Ethernet device has already set the Qbv EST configuration
before using ptp to synchronize the time adjustment, the Qbv base time
may change to be the past time of the new current time. This is not
allowed by hardware.

This patch calculates and re-configures the Qbv basetime after ptp time
adjustment.

Xiaoliang Yang (3):
  net: stmmac: separate the tas basetime calculation function
  net: stmmac: add mutex lock to protect est parameters
  net: stmmac: ptp: update tas basetime after ptp adjust
