This delay is a function of the PHY clock speed and can range from 5-50 ms. This delay must be taken into account on core reset and force modes. A full explanation is provided in the patch commit log and code comments. This revision of the series increases the IDDIG delay to 100 ms. Some rockchip platforms seem to timeout even with 50 ms so I have doubled this.
