Subject: [PATCH 1/2] ARM: sun8i: a83t: add dwmac-sun8i ethernet driver
Date:   Tue,  7 Nov 2017 21:13:25 +0100
Message-Id: <20171107201326.17401-1-clabbe.montjoie@gmail.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

The dwmac-sun8i is an ethernet MAC hardware that support 10/100/1000 speed.
This patch enable the dwmac-sun8i on the Allwinner a83t SoC Device-tree.
