If you don't support parity or charactive size then you should be forcing
those bits in the tty->termios so that the caller sees what settings they
get. tty_termios_copy_hw is close to what you need except that you can
support IGNPAR.
You also want to provide the actual baud rate chosen (see how 8250.c does
it using tty_termios_encode_baud_rate().

NAK
TTY_MAJOR 64+ is the 8250 driver and ttyS is the 8250 driver name. You
should be using a dynamic major (0) for all new drivers and you need to
pick a different and unused ttyXXX format name.
