Hello,
I'm using OMAP3530 with custom board. I have enabled all power mode features as described in PSP wiki, but it still fails to enter any state different from state0.

On trying to enable uart as wakeup source I get the following:
echo enabled > /sys/devices/platform/omap/omap_uart.2/power/wakeup
cat /sys/devices/platform/omap/omap_uart.2/power/wakeup
#> disabled
echo 1 > /sys/devices/platform/omap/omap_uart.2/sleep_timeout
console hangs
Thanks for any suggestions,
Ran
