*Enable support for UART console input expired mechanism*

Type: ``bool``

Help
====

.. code-block:: none

    This option allows a notification to the power management module that
    the module for UART console is in use now. If the interval of console
    module doesn't receive any input message exceeds expired timeout, such
    as UART_CONSOLE_INPUT_EXPIRED_TIMEOUT, the power management module is
    allowed to enter sleep/deep sleep state and turn off the clock of UART
    console module. This mechanism gives a window in which the users can
    organize input message if CONFIG_PM is enabled.
