Subject: device tree binding for poly-phased regulators

Hi!

Documentation/devicetree/bindings/mfd/axp20x.txt nicely describes the
capabilities of the X-powers PMICs; however, it seems polyphasing is
left to comments only.

May I suggest to add a property "poly-phased", just to get the discussion
started? It could be a simple property in the current case for the axp803
and axp806 ("poly-phased with you-know-which") or a phandle in the future.

BTW the axp803 datasheet is quite terse in that respect: is there one
"master" reulator whose settings are copied or does a driver have to keep
them in sync.

Anyway, comments welcome!

	Torsten
