OK, so do we believe this list is complete?
Wakup from deep sleep CPU state can be:
1. wifi
2. GSM
3. usb
4. buttons (both AUX and power)
5. motion sensor
Andy, anything else wired up to the EINT[15:0] range?

Somebody in the thread at some point said:
Andy, Werner -
today Tony and I wondered whether Motion Sensor activity can wakeup
the
CPU from deep sleep.
Right now we believe wakeup from deep sleep CPU can be caused by:
1. wifi
2. GSM
3. usb
Anything else? We think bluetooth, motion sensors cannot.
I didn't look at this mechanism until now, but it appears from the
Samsung datasheet that any of the EINT[15:0] interrupts can wake from
what they call "SLEEP", ie, CPU powered down.
One of the motion sensors interrupts maps to this range (the "top" one
on GPF0 --> EINT[0]) and one doesn't (the bottom one on GPG8 -->
EINT[*16*]).
If I understood it then you could probably do something with that if
the
idea is shaking it awake or so on.
