- comment "Capabilities"
- config SERIAL_HAS_DRIVER
- bool
- help
- This is an option to be enabled by individual serial driver
- to signal that there is a serial driver. This is being used
- by other drivers which are dependent on serial.
- config SERIAL_SUPPORT_ASYNC
- bool
- help
- This is an option to be enabled by individual serial driver
- to signal that the driver and hardware supports async operation.
- config SERIAL_SUPPORT_INTERRUPT
- bool
- help
- This is an option to be enabled by individual serial driver
- to signal that the driver and hardware supports interrupts.
- config UART_USE_RUNTIME_CONFIGURE
- bool "Enable runtime configuration for UART controllers"
- default y
- 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.
- config UART_ASYNC_API
- bool "Enable new asynchronous UART API [EXPERIMENTAL]"
- depends on SERIAL_SUPPORT_ASYNC
- help
- This option enables new asynchronous UART API.
- config UART_INTERRUPT_DRIVEN
- bool "Enable UART Interrupt support"
- depends on SERIAL_SUPPORT_INTERRUPT
- help
- This option enables interrupt support for UART allowing console
- input and other UART based drivers.
- config UART_LINE_CTRL
- bool "Enable Serial Line Control API"
- help
- This enables the API for apps to control the serial line,
- such as baud rate, CTS and RTS.
- Implementation is up to individual driver.
- Says no if not sure.
- config UART_DRV_CMD
- bool "Enable driver commands API"
- help
- This enables the API to send extra commands to drivers.
- This allows drivers to expose hardware specific functions.
- Says no if not sure.
