From mboxrd@z Thu Jan 1 00:00:00 1970 From: Andrew Jeffery Subject: [PATCH net-next v2 1/4] dt-bindings: net: Add aspeed,ast2600-mdio binding Date: Wed, 31 Jul 2019 15:09:56 +0930 Message-ID: <20190731053959.16293-2-andrew@aj.id.au> References: <20190731053959.16293-1-andrew@aj.id.au> Mime-Version: 1.0 Content-Transfer-Encoding: 8bit Return-path: In-Reply-To: <20190731053959.16293-1-andrew@aj.id.au> Sender: netdev-owner@vger.kernel.org To: netdev@vger.kernel.org Cc: Andrew Jeffery , davem@davemloft.net, robh+dt@kernel.org, mark.rutland@arm.com, joel@jms.id.au, andrew@lunn.ch, f.fainelli@gmail.com, hkallweit1@gmail.com, devicetree@vger.kernel.org, linux-arm-kernel@lists.infradead.org, linux-aspeed@lists.ozlabs.org, linux-kernel@vger.kernel.org List-Id: devicetree@vger.kernel.org The AST2600 splits out the MDIO bus controller from the MAC into its own IP block and rearranges the register layout. Add a new binding to describe the new hardware.
