This is a note to let you know that I've just added the patch titled

serial: 8250: add uart_config entry for PORT_RT2880

to my tty git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty.git
in the tty-linus branch.

The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.)

The patch will hopefully also be merged in Linus's tree for the next -rc kernel release.

If you have any questions about this process, please let me know.

Subject: serial: 8250: add uart_config entry for PORT_RT2880

This adds an entry to the uart_config table for PORT_RT2880 enabling rx/tx FIFOs. The UART is actually a Palmchip BK-3103 which is found in several devices from Alchemy/RMI, Ralink, and Sigma Designs.
