General informations

The Linux kernel configuration item CONFIG_SERIAL_8250_FINTEK has multiple definitions:

Support for Fintek variants found in drivers/tty/serial/8250/Kconfig

The configuration item CONFIG_SERIAL_8250_FINTEK:

• prompt: Support for Fintek variants
• type: bool
• depends on: CONFIG_SERIAL_8250 && CONFIG_HAS_IOPORT
• defined in drivers/tty/serial/8250/Kconfig
• found in Linux kernels: 6.5–6.12, 6.13-rc+HEAD
• modules built: 8250_fintek

Help text

Selecting this option will add support for the RS232 and RS485 capabilities of the Fintek F81216A LPC to 4 UART as well similar variants.

If this option is not selected the device will be configured as a standard 16550A serial port, however the device may not function correctly without this option enabled.

If unsure, say N.
