Subject: [PATCH net-next v2 11/13] arm64: dts: marvell: mcbin: enable the fourth network interface
Date:   Fri,  4 May 2018 15:56:41 +0200
Message-Id: <20180504135643.23466-12-antoine.tenart@bootlin.com>
In-Reply-To: <20180504135643.23466-1-antoine.tenart@bootlin.com>
References: <20180504135643.23466-1-antoine.tenart@bootlin.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

This patch enables the fourth network interface on the Marvell
Macchiatobin. It is configured in the 2500Base-X PHY mode. The SFP cage
is also described.
