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 SERIAL_INIT_PRIORITY int "Serial init priority" default KERNEL_INIT_PRIORITY_DEVICE help Serial driver device initialization priority. 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. comment "Serial Drivers" source "drivers/serial/Kconfig.b91" source "drivers/serial/Kconfig.ns16550" source "drivers/serial/Kconfig.mcux" source "drivers/serial/Kconfig.mcux_flexcomm" source "drivers/serial/Kconfig.mcux_iuart" source "drivers/serial/Kconfig.mcux_lpsci" source "drivers/serial/Kconfig.mcux_lpuart" source "drivers/serial/Kconfig.miv" source "drivers/serial/Kconfig.imx" source "drivers/serial/Kconfig.stellaris" source "drivers/serial/Kconfig.native_posix" source "drivers/serial/Kconfig.usart_sam" source "drivers/serial/Kconfig.uart_sam" source "drivers/serial/Kconfig.stm32" source "drivers/serial/Kconfig.nrfx" source "drivers/serial/Kconfig.altera_jtag" source "drivers/serial/Kconfig.cc13xx_cc26xx" source "drivers/serial/Kconfig.cc32xx" source "drivers/serial/Kconfig.cmsdk_apb" source "drivers/serial/Kconfig.sifive" source "drivers/serial/Kconfig.esp32" source "drivers/serial/Kconfig.esp32c3_rom" source "drivers/serial/Kconfig.esp32s2_rom" source "drivers/serial/Kconfig.gecko" source "drivers/serial/Kconfig.leuart_gecko" source "drivers/serial/Kconfig.msp432p4xx" source "drivers/serial/Kconfig.numicro" source "drivers/serial/Kconfig.sam0" source "drivers/serial/Kconfig.psoc6" source "drivers/serial/Kconfig.pl011" source "drivers/serial/Kconfig.rv32m1_lpuart" source "drivers/serial/Kconfig.litex" source "drivers/serial/Kconfig.rtt" source "drivers/serial/Kconfig.xlnx" source "drivers/serial/Kconfig.xmc4xxx" source "drivers/serial/Kconfig.lpc11u6x" source "drivers/serial/Kconfig.npcx" source "drivers/serial/Kconfig.apbuart" source "drivers/serial/Kconfig.rcar" source "drivers/serial/Kconfig.xec" source "drivers/serial/Kconfig.test" endif # SERIAL
