Subject: [PATCH net-next v4 0/7] add hwtstamp_get callback to phy drivers

PHY drivers are able to configure HW time stamping and are not able to
report configuration back to user space. Add callback to report
configuration like it's done for net_device and add implementation to
the drivers.

v3 -> v4:
* drop patches 5 and 6 from previous version as these drivers need logic
  upgrade to report configuration correctly. I'll send these updates as
  separate patchset
v2 -> v3:
* remove SIOCGHWTSTAMP in phy_mii_ioctl() as we discourage usage of
  deprecated interface
v1 -> v2:
* split the first patch to rename part and add new callback part
* fix netcp driver calling mii_timestamper::hwtstamp

Vadim Fedorenko (7):
  phy: rename hwtstamp callback to hwtstamp_set
  phy: add hwtstamp_get callback to phy drivers
  net: phy: broadcom: add HW timestamp configuration reporting
  net: phy: dp83640: add HW timestamp configuration reporting
  phy: mscc: add HW timestamp configuration reporting
  net: phy: nxp-c45-tja11xx: add HW timestamp configuration reporting
  ptp: ptp_ines: add HW timestamp configuration reporting
