- reset-gpios: The GPIO phandle and specifier for the PHY reset signal.
- reset-delay-us: Delay after the reset was asserted in microseconds.
- reset-assert-us: Delay after the reset was asserted in microseconds.
If this property is missing the delay will be skipped.

- reset-deassert-us: Delay after the reset was deasserted in microseconds.
