Date: Wed, 7 Jun 2017 08:23:04 +0800 From: Icenowy Zheng <icenowy@...c.io> To: Maxime Ripard <maxime.ripard@...e-electrons.com>, Chen-Yu Tsai <wens@...e.org> Cc: linux-arm-kernel@...ts.infradead.org, devicetree@...r.kernel.org, linux-kernel@...r.kernel.org, linux-sunxi@...glegroups.com, Icenowy Zheng <icenowy@...c.io> Subject: [PATCH 2/3] arm64: allwinner: h5: enable dwmac-sun8i for Orange Pi Prime Add the required DT parts to enable Ethernet (dwmac-sun8i driver) on the Orange Pi Prime board. It uses an external Realtek RTL8211E PHY connected via RGMII to provide GbE network. This includes the regulator (which is controlled by a GPIO pin) and the actual Ethernet MAC node, referring the RGMII pins of the device.
