Hi,

First and foremost, thank you for doing this job. It is indeed always a
good idea to submit work to the community.

In a separate patch please. You will also have to sent it to
linux-fbdev-devel mailing list.

Anyway, I think the driver is not the place to add this configuration.
You will have to configure it in the board file:
default_lcdcon2 field of the atmel_lcdfb_info structure.
Check the arch/avr32/boards/atngw100/mrmr.c file as an example.
