N900 sleep mode (in 4.5-rc0, if that matters)

Hi! I enabled the sleep leds, and am using following script to set the machine up for power management: #!/bin/bash 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/
