UART DRIVER on 2.6.15

UART DRIVER on 2.6.15

[Ladislav Klenovič]

Hi,
just a simple question, is uart driver for kernel 2=2E6=2E15 complete=2E=
=20
There are some parts like:
 void scc1_lineif(struct uart_cpm_port *pinfo)
{
        /* XXX SCC1: insert port configuration here */
        pinfo->brg =3D 1;
}
=2E=2E=2E=2E
that seems to incomplete=2E Am I able to do something with SCC1 with th=
e current cpm_uart code?

Maybe stupid question, is there any way (is it possible) to import old =
uart driver from kernel 2=2E4=2Ex to kernel 2=2E6=2Ex

Regards,
Ladislav Klenovic

It is clear, that per-board tune-up is too specific to be kept within drivers/ and now it is accomplished in the board setup code. 

Just have a look at arch/ppc/platforms/mps866ads_setup.c The thing you'll have to do is implement the pin tune-up for your board in a function, and set the callback pointer to it - it will be executed at the time UART initializes its resources.
