Subject: [PATCH net-next v3 1/5] dt-bindings: net: renesas,rzn1-gmac:
 Document RZ/N1 GMAC support

From: Clément Léger <clement.leger@...tlin.com>

The RZ/N1 series of MPUs feature up to two Gigabit Ethernet controllers.
These controllers are based on Synopsys IPs. They can be connected to
RZ/N1 RGMII/RMII converters.

Add a binding that describes these GMAC devices.
