[PATCH v3 1/5] dt-bindings: net: Add HPE GXP UMAC MDIO

From: nick . hawkins
Date: Wed Aug 16 2023 - 17:57:21 EST


From: Nick Hawkins <nick.hawkins@xxxxxxx>

Provide access to the register regions and interrupt for Universal
MAC(UMAC). The driver under the hpe,gxp-umac-mdio will provide an
interface for managing both the internal and external PHYs.
