Hi Vignesh,

No, because this GPIO actually is not used as a PHY reset.

After reviewing the hardware, it turned out that this signal is a
board-level enable signal required for the PHY to operate, rather than
a reset line.
The previous reset-assert-us and reset-deassert-us values were
associated with the incorrect modelling of this GPIO as a reset, and
are not longer needed.

Thank you!

Best Regards,
Stefano
