Subject: [PATCH v2 1/2] ARM: sun8i: a83t: add dwmac-sun8i device node
Date: Thu, 9 Nov 2017 09:29:49 +0100 [thread overview]
Message-ID: <20171109082950.21124-2-clabbe.montjoie@gmail.com> (raw)
In-Reply-To: <20171109082950.21124-1-clabbe.montjoie@gmail.com>
The dwmac-sun8i is an ethernet MAC hardware that support 10/100/1000 speed.
This patch add support for it on the Allwinner a83t SoC Device-tree.
This patch add the emac device node and the related RGMII pins node.
