With v3.16-rc4 the PM features for omap3 should be working
finally for device tree based booting. At lest beaglexm and
3xxevm should work.
Maybe you are using legacy booting path to idle the UARTs still?
FYI, I'm doing this to find the UART entries:
uarts=$(find /sys/class/tty/ttyO*/device/power/ -type d)
for uart in $uarts; do
echo 3000 > $uart/autosuspend_delay_ms
done
uarts=$(find /sys/class/tty/ttyO*/power/ -type d)
for uart in $uarts; do
echo enabled > $uart/wakeup
echo auto > $uart/control
done
echo 1 > /sys/kernel/debug/pm_debug/enable_off_mode

Tony
