From: Olliver Schinagl <o.schinagl@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.

NAK. This does much more than enabling the otg port.

Neither wholesale re-writing the regulator node or hooking up the 
dcdc2 regulator to the operating points definition is required in order 
to enable the otg port.  

At the very least you need to split your patches and describe them 
properly rather than trying to get additional changes that are likely 
to cause further discussion through unnoticed using a misleading 
subject.

Rgds,
Iain

Yeah I just noticed as well that for some reason i've sent a merged patch :(

I all ready fixed it locally this morning and will re-send the patches. 
I wonder what I did though ..

Sorry again,

Olliver
