Hi Alexandre,

I applied this patch on top of linux-next. I am able to wake up from rtc
from suspend to memory on am33-bbb.
Also i tried your commands:
echo +5 > /sys/class/rtc/rtc0/wakealarm ; echo mem > /sys/power/state

That also worked fine.
For am335x-boneblack as well this patch works.
Ok, thanks a lot for confirming, I'll try to fix my setup, I'm probably
just missing the m3 firmware.
Yes. Just try:
echo mem > /sys/power/state
and try waking up from uart and if that fails then we need to look at m3
firmware. If this works only then move to rtcwake.
