rx-internal-delay-ps:
description: |
RGMII Receive PHY Clock Delay defined in pico seconds. This is used for
PHY's that have configurable RX internal delays. If this property is
present then the PHY applies the RX delay.
So the property is optional. It being missing should not generate a
warning. Please just use the default of 2ns. This makes the usage the
same as the other drivers using phy_get_internal_delay().
