+description:
+ HPE GXP 802.3 10/100/1000T Ethernet Unifed MAC controller.
+ Device node of the controller has following properties.

+properties:
+ compatible:
+ const: hpe,gxp-umac
+
+ use-ncsi:
+ type: boolean
+ description:
+ Indicates if the device should use NCSI (Network Controlled
+ Sideband Interface). Only one of the two MACs can support
+ NCSI and it requires there to be a physical connection on
+ the board to be present. This property indicates that
+ physical connection is present and should be used.
