UART TL 16C550C on custom mpc5200 board

UART TL 16C550C on custom mpc5200 board

[Achim Machura]

Hello,

i'm working on a custom 5200 board with kernel 2.4.25.
I have to integrate an UART 16C550C in /dev/ttyXX.
Does everyone knows an existing driver i can modify for use with this chip?

thanks

Achim

You don't have to modify much; just  configure  the  interrupts,  add
definitions  of  STD_SERIAL_OP  for  all  ports to your board file in
arch/ppc/platforms/, and make sure that there is no conflict in major
numbers between drivers/char/serial.c and any other serial driver  in
your system.

Best regards,
