This patch adds the new AXP209 node on the OLinuXino Lime2.
The previously submitted otg enablement patch is needed to avoid merge
conflicts.

The Olimex OLinuXino Lime2 uses the same AXP209 as was recently
introduced this driver for its power regulation.

Why are you removing that regulator?

This is outside of the operating voltages of the CPU.

You're changing the boundaries, why?

This is really just a placeholder, rather than an actual regulator.

>From the bindings:

- <input>-supply: a phandle to the regulator supply node. May be omitted if
                  inputs are unregulated, such as using the IPSOUT output
                  from the PMIC.

The old boundaries seem to be from a very old dts, where we were
listing the regulators' supported voltage range, instead of what
the SoC could take.

Olliver you should explain all this in the commit log, probably
starting with something like "update the dts to use axp209.dtsi
, comply with axp20x bindings, and set proper voltage ranges for
the regulators".

Is it very old? just checked the cubies in maxime's sunxi next and those where still there. I actually wrote these patches ages ago and forgot to submit them whats worse is on my behave, i didn't properly check for changes. Now that you mention it however, i do recall the discussion about these values. I will update them accordingly with the correct values.

Sorry,
Olliver
