A uart driver controls the hardware, which talks to the serial core, which talks to the tty layer (the serial core is a tty driver). > For instance, take a look of serial_core.c > (http://lxr.linux.no/source/drivers/serial/serial_core.c#L2059).Both are > related but I cannot understand the relationship and which one you > should use in which case. > To register a serial device driver should I use: tty_register_driver() > or uart_register_driver ? Depends on what exactly your hardware looks like. If it is a uart like chip, use the serial core. Otherwise, use the tty core. But I'm really supprised that we don't support your device already, what kind is it? thanks, greg k-h -- Kernelnewbies: Help each other learn about the Linux kernel.
