CONFIG_UART_USE_RUNTIME_CONFIGURE

Enable runtime configuration for UART controllers

Type: bool

Help

Enable runtime configuration of UART controllers.
This allows applications to call uart_configure() to
configure the UART controllers at runtime, and calling
uart_config_get() to retrieve configuration. If this is
disabled, UART controllers rely on UART driver's
initialization function to properly configure
the controller.

Say y if unsure. Disable this to reduce footprint for
applications that do not require runtime UART configuration.
