From mboxrd@z Thu Jan 1 00:00:00 1970 From: Chen-Yu Tsai Subject: [PATCH net-next v2 12/15] ARM: dts: sun8i: r40: Add device node and RGMII pinmux node for GMAC Date: Wed, 2 May 2018 00:12:24 +0800 Message-ID: <20180501161227.2110-13-wens@csie.org> References: <20180501161227.2110-1-wens@csie.org> Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Return-path: In-Reply-To: <20180501161227.2110-1-wens@csie.org> List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Sender: "linux-arm-kernel" Errors-To: linux-arm-kernel-bounces+linux-arm-kernel=m.gmane.org@lists.infradead.org To: Maxime Ripard , Michael Turquette , Stephen Boyd , Giuseppe Cavallaro , Rob Herring , Mark Rutland , Mark Brown Cc: devicetree@vger.kernel.org, netdev@vger.kernel.org, Chen-Yu Tsai , Corentin Labbe , linux-clk@vger.kernel.org, linux-arm-kernel@lists.infradead.org, Icenowy Zheng List-Id: devicetree@vger.kernel.org The R40 SoC has a GMAC (gigabit capable Ethernet controller). Add a device node for it. The only publicly available board for this SoC uses an RGMII PHY. Add a pinmux node for it as well. Since this SoC also has an old 10/100 Mbps EMAC, which also has an MDIO bus controller, the MDIO bus for the GMAC is labeled "gmac_mdio".
