Thanks, I will be more careful on next patch series version.

Yes, i.e. to select the default and better timestamp on a board.

On that case there is not really solution, but be aware that
CONFIG_PHY_TIMESTAMPING need to be activated to allow timestamping on the PHY.
Currently in mainline only few (3) defconfig have it enabled so it is really
not spread, maybe I could add more documentation to prevent further regression
issue when adding support of timestamp to a PHY driver.

Köry
