OMAP/serial: Add support for driving a GPIO as DTR.
OMAP hardware doesn't provide a phyisical DTR line, but some configurations may need a DTR line which tracks whether the device is open or not. So allow a gpio to be configured as the DTR line. Signed-off-by: NeilBrown <neilb@suse.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
