OK this v5 is applied.

Laxman does this GPIO also have open drain and/or open source
handling?

Then you might want to look into supporting that too as I just added
support for native single-endedness to gpiolib, c.f.:
http://marc.info/?l=linux-gpio&m=146011780301280&w=2

It would be nice if you also implement .get_direction() which
makes debugfs and initial reading of the state of the lines
more accurate.
