What about a step by step approach. First we add this code to the
8250_core, and then I remove all the specific driver
TIOCSRS485 handling and manage it through serial_core.c
Right now these are the drivers using it:
drivers/tty/serial/8250/8250_core.c: case TIOCSRS485:
drivers/tty/serial/atmel_serial.c: case TIOCSRS485:
drivers/tty/serial/crisv10.c: case TIOCSRS485:
drivers/tty/serial/max310x.c: case TIOCSRS485:
drivers/tty/serial/mcf.c: case TIOCSRS485: {
drivers/tty/serial/omap-serial.c: case TIOCSRS485:
rivers/tty/serial/sc16is7xx.c: case TIOCSRS485:
Regards!
