Why is a this new field added (and not described in the changelog.) Kevin [1] commit 9574f36fb801035f6ab0fbb1b53ce2c12c17d100 Author: NeilBrown <neilb@suse.de> Date: Mon Jul 30 10:30:26 2012 +1000 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.
