OMAP-L138: Are open source Linux 2.6.31 Drivers available for TI external dual asynchronous UART (such as TL16C2550)

Other Parts Discussed in Thread: TL16C2550, OMAP-L138

Can anyone help me determine if there are Linux drivers available for TI dual UART devices such as TL16C2550 ( http://focus.ti.com/docs/prod/folders/print/tl16c2550.html ). I have a customer using the OMAP-L138 on a prorietary hardware design that ran into some pin multiplexing issues that needed to add some external UART chips to the asynchronous interface. If TI specific drivers do not exist if there are standard UART drivers that we could use as a starting point for similar UART's that would be better than nothing!

AMENDED: Here is some more information I have found. It looks like "16550" support is in the standard "8250" driver (http://en.wikipedia.org/wiki/16550_UART) which can be found here:

8250.c – ( http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.31.y.git;a=blob;f=drivers/serial/8250.c;h=fb867a9f55e94957e1a59ec5cb1f78b85865797e;hb=HEAD )

8250.h – ( http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.31.y.git;a=blob;f=drivers/serial/8250.h;h=520260326f3dfeb64b67643e1a27938e733d71fc;hb=HEAD )

I still need to know if the OMAP-L138 platform supports these external TL16C2550 UART's on the asynchronous bus though.
