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

[Olliver Schinagl]

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

This patch enables the recently introduced OTG support for the OLinuXino Lime2.
Tested with a keyboard and some USB mass-storage flash-drives and various
hotplug.

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

[Olliver Schinagl]

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.

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

[Iain Paton]

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,
