The short answer is that we currently only support wakeup on the rqOnOff input. Some products support waking up with the touch panel or ADSmartIO keypad inputs.
The longer answer is that the StrongARM can wake up from a change in any one of 28 GPIO lines (16 on XScale PXA255: signal transition on GP0-15). This feature is configured with the PWER (Power Manager Wakeup Enable) register. If you would like us to enable this feature for your application email us details about what you have in mind.
