dts: added constraints for baudrates of UARTs in Nordic SOCs (6d34d6be) · Commits · Wenxi XU / zephyr

UARTs in Nordic devices only support a specified list of baud rates. Choosing a different baud rate without this patch will cause a runtime error, whereas with the constraint, this mistake is already found in dts construction with a useful error message. Signed-off-by:
