Subject[Patch net-next v14 01/13] dt-bindings: net: make internal-delay-ps based on phy-mode
Date
From: Prasanna Vengateshan <prasanna.vengateshan@microchip.com>

*-internal-delay-ps properties would be applicable only for RGMII interface
modes.

It is changed as per the request.

Ran dt_binding_check to confirm nothing is broken.
