Disable Wake-up from UART0

[PRAMOD MAURYA]

Hi All;
-------


I want disable/enable deep sleep using the following command:

echo enabled > /sys/devices/44000000.ocp/44e09000.serial/power/wakeup
echo "disabled > /sys/devices/44000000.ocp/44e09000.serial/power/wakeup


When i disable WAKE-UP from uart then interface face is disable but it still wake-up from the UART0::

echo "disabled > /sys/devices/44000000.ocp/44e09000.serial/power/wakeup

This is the setting of the currnt wakeup sources:

cat /sys/kernel/debug/wakeup_sources

name             ................

wakeup.gpiokey   ................

44e3e00.rtc      ................

alarmtimer       ................

as you see there is no UART to see!! but i am still able to wake the system up from UART ??
