-config NS16550_SERIAL
- bool "NS16550 UART or compatible"
- depends on DM_SERIAL
- default y if X86 || PPC || ARCH_ROCKCHIP
- help
- Support NS16550 UART or compatible with driver model. This can be
- enabled in the device tree with the correct input clock frequency.
- If the input clock frequency is not defined in the device tree,
- the macro CONFIG_SYS_NS16550_CLK defined in a legacy board header
- file will be used. It can be a constant or a function to get clock,
- eg, get_serial_clock().
