From 23af610e09f78822ade4067a400ff9ceb5b020ea Mon Sep 17 00:00:00 2001
From: Oliver Schinagl <oliver@schinagl.nl>
Date: Tue, 3 Dec 2013 12:10:11 +0100
Subject: [PATCH] ARM: sun4i: dts: Add ahci / sata support
This patch adds sunxi sata support to A10 boards that have such a connector.
Some boards also feature a regulator via a GPIO and support for this is also
added.
