> These settings are based on the "Recommended Sleep Sequences for

>
> These settings assume most of the regulators are under control of
> Linux, and twl4030 only cuts off VDD1 and VDD2 during off-idle as
> Linux cannot do it.
>
> For any board specific changes to these, let's patch them in as
> changes to the generic data in the follow-up patches. This keeps
> the board specific changes small.
>
> Note that this does not consider the twl5030 errata 27 and 28.
> That can be added later on after it has been tested. For more
> information about errata 27 and 28, please see:
