[Patch net-next v14 01/13] dt-bindings: net: make internal-delay-ps based on phy-mode

From: Arun Ramadoss
Date: Thu Jun 30 2022 - 06:21:42 EST


From: Prasanna Vengateshan <prasanna.vengateshan@xxxxxxxxxxxxx>

*-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.
