Need to think about it a bit more, but I think we can have generic
scripts based on the tables in "Recommended Sleep Sequences for
the Zoom Platform" pdf at:

http://omappedia.com/wiki/File:Recommended_Sleep_Sequences_Zoom.pdf

Then we can have a function that patches in board specific stuff
as needed as changes to the generic rconfig table.

I'll take a look at that, let's see how that works. If that works,
the board specific increments to the generic data should be pretty
small and the data can easily live in the twl4030-power.c with no
need to stuff it into the .dts files.

BTW, the situation is also a bit different from the original N900
kernel as we now have runtime PM and drivers can easily manage their
regulators.

Regards,

Tony
