Subject: [PATCH net-next v6 1/7] dt-bindings: net: renesas,rzn1-gmac: Document RZ/N1 GMAC support
Date: Fri, 10 May 2024 09:38:08 +0200 [thread overview]
Message-ID: <20240510-rzn1-gmac1-v6-1-b63942be334c@bootlin.com> (raw)
In-Reply-To: <20240510-rzn1-gmac1-v6-0-b63942be334c@bootlin.com>
From: Clément Léger <clement.leger@bootlin.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.
