great, just take into account the deep vs. shallow suspend modes :-)
The original regulator-state changes did happen when we had this suspend
instability (counter and gpioint stuff) and I did go with the values similar to
the rk3288-evb, as this was the only one resuming at all at the time. So I
guess I never looked to closesly what it did, as long as the system came out
of suspend sucessfully again :-)
