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

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
