The clocks are disabled after an inactivity timer (default 5 seconds of idle.) I've tested the UART idle parts on n810 which seem to work, but hitting retention on n810 seems broken in current linux-omap. Tony merged a patch[2] from me last week which was crashing going into retention, but even with that I'm not able to wakeup from retention. This could be something as simple as the wakeup event sources are not configured correctly for n810, but I did not debug further.
