Hello Kevin,

On most OMAP3 platforms, the twl4030 IRQ line is connected to the

Boards that hook up the twl4030 differently can easily override this
in their board-specific DTS file.
This allows RTC wake from off-mode to work again on OMAP3-based
platforms with twl4030. Tested on 3530/Beagle, 3730/Beagle-xM,
3530/Overo, 3730/Overo-STORM.

Here you are making the TWL4030 to explicitly depend on OMAP3. Could
this chip be
used by another target? If the case, I would put this piece of code in
the files
including twl4030. Otherwise it's ok here.

I will test this afternoon on an Overo.
