[PATCH] ARM: dts: sunxi: enable otg port on the sun7i-a20-olinuxino-lime2

[Olliver Schinagl]

From: Olliver Schinagl <o.schinagl at ultimaker.com>

This patch enables the musb-otg USB controller on the Lime2. The Lime2
differs from the Lime1 series in pins used for usb0 power.

Tested on a OlinuXino Lime2-4GB.
