While doing this, its better to keep the header files you are adding in
sorted order.

You dont need to include this file here.

You don't actually register GPIO for hawkboard?

This the SoC changes can be done in 3/7 itself. I have done that in my
v3.11/gpio branch. Can you fix the issues I pointed out and reply to
this mail with an updated 5/7?
