[PATCH 3/3] ARM: sunxi: dts: Add ahci support to a few A10 and A20 boards

From: oliver
Date: Wed Dec 04 2013 - 07:17:53 EST

From: Oliver Schinagl <oliver@xxxxxxxxxxx>

This patch adds sunxi sata support to A10 and A20 boards that have such
a connector. Some boards also feature a regulator via a GPIO and support
for this is also added.
