Ideally not all of them, turning the ones that aren't needed off is
definately on my list of things to do (together with the other
pheripherals, leds, hw. keys etc).
For the first patch i do prefer to keep them on so we can have get some
more testing with this board before fine-tuning those things (fwiw,
the rockchip evb board and others with essentially the same pmic setup
all also have them always-on)
