Subject: [PATCH 3/3] ARM: sunxi: dts: Add ahci support to a few A10 and A20 boards
From: Oliver Schinagl <oliver@...inagl.nl>
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.
Signed-off-by: Olliver Schinagl <oliver@...inagl.nl>
