This adds three new functions (or in one case to be more exact makes it always available) tty_termios_copy_hw Copies all the hardware settings from one termios structure to the other. This is intended for drivers that support little or no hardware setting tty_termios_encode_baud_rate Allows you to set the input and output baud rate in a termios structure. A driver is supposed to set the resulting baud rate from a request so most will want to use this function to set the resulting input and output rates to match the hardware values. Internally it knows about keeping Bxxx encoding when possible to maximise compatibility. tty_encode_baud_rate As above but for the tty's own current termios structure I suspect this will initially need some tweaking as it gets enabled by driver patches over the next few mm cycles so consider this lot -mm only for the moment so it can stabilize and end up neat before it goes to base. I've tried not to break any obscure architectures - if you get a speed you can't represent the code will print warnings on non updated termios systems but not break. Once this is merged and seems sane I've got a growing pile of driver updates to use it - notably for USB serial drivers.
