That core_pwrdm shows only up on dra7. However with both drivers (mine and the current omap serial) the UART went down after three secs (as expected) and didn't accept any characters while writing on the console. If I wrote something on it via network (like echo a > /dev/ttyO0) it came back and was working as long as I kept it busy. The thing is that RX does not wake it up. Any idea?
To wakeup from UART you need: 1) Append no_console_suspend to bootargs 2) echo enabled > /sys/devices/ocp.3/4806a000.serial/tty/ttyO0/power/wakeup -- To unsubscribe from this list: send the line "unsubscribe linux-serial" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
