From cf454a47b64ef78ff85b097c8cb404120c14e6a5 Mon Sep 17 00:00:00 2001
From: Hans de Goede <hdegoede@redhat.com>
Date: Fri, 3 Jan 2014 10:27:51 +0100
Subject: [PATCH] ARM: sun7i: dt: Add ahci / sata support
This patch adds sunxi sata support to A20 boards that have such a connector.
Some boards also feature a regulator via a GPIO and support for this is also
added.
