Anton Vorontsov 24d481ecae 8250: Now honours baud rate lower bounds ... A platform clock drives 8250 ports in most SOC systems, the clock might run at high frequencies, and so it's not always possible to downscale uart clock to a desired value. Currently the 8250 uart driver accepts not supported baud rates, and what is worse, it is doing this silently, and then passes not accepted values to a new termios, so userspace has no chance to catch this kind of errors (userspace verifies that settings were accepted by reading back and comparing the settings). This patch fixes the issue by passing minimum baud rate to the uart_get_baud_rate() call, the call should take care of all bounds, so userspace should now report: # stty -F /dev/ttyS0 speed 300 115200 stty: /dev/ttyS0: unable to perform all requested operations p.s. uart_get_baud_rate() falls back to 9600, which still might be too low for some 10 GHz platforms, but that's a separate issue, and we can wait with fixing this till we find such a platform.
