Date: Tue, 17 Dec 2013 21:21:49 +0100 Message-Id: <1387311713-1926-1-git-send-email-andrew@lunn.ch> X-Mailer: git-send-email 1.7.10.4 Sender: linux-ide-owner@vger.kernel.org Precedence: bulk List-ID: X-Mailing-List: linux-ide@vger.kernel.org Describe the binding for the Marvell MVEBU SATA phy. This driver can be used at least with Kirkwood, Dove and maybe others. Additionally, update the SATA binding with the properties to link to the phy nodes.
