CONFIG_UART_CONSOLE_INPUT_EXPIRED

Enable support for UART console input expired mechanism

Type: bool

Help

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.
