Are you enabling UART wakeups?

They are disabled by default, so you need to:

echo enabled > /sys/devices/platform/omap/omap_uart.2/tty/ttyO2/power/wakeup

No, I was actually not enabling the UART wakeups.  But I tried it now
but it still doesn't work. :(

You definitely need that.

I have no_console_suspend in bootargs.  Without it, it didn't work with
3.2 either.

If you want to use no_console_suspend -- which is not recommended -- then 
you'll need 

http://www.spinics.net/lists/linux-omap/msg65786.html

but best simply not to use no_console_suspend.
