Subject: [PATCH 5/5] arm64: allwinner: h6: add support for the Ethernet on Pine H64
Date:   Sun, 22 Jul 2018 13:39:55 +0800
Message-Id: <20180722053955.25266-6-icenowy@aosc.io>
In-Reply-To: <20180722053955.25266-1-icenowy@aosc.io>
References: <20180722053955.25266-1-icenowy@aosc.io>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

The Pine H64 board has an Ethernet port, which is connected to a
RTL8211E PHY, then the PHY is connected to the MAC on H6 SoC.

Add support for the Ethernet port.
