- From: Hans de Goede <[email protected]>
- Date: Fri, 3 Jan 2014 10:27:51 +0100
- Subject: [PATCH] ARM: sun7i: dts: 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.
