Hi
Yes i need to add the gpio-controller and #gpio-cells. But i'm not
exactly sure what gpio-cells means and its difficult to find in
documentation.
I found this in the documentation:
#gpio-cells: The first cell is the GPIO number and the second cell is
used to specify the GPIO polarity.
This device only supports inputs so the gpio-cells option needs to be
<1> or ??
#gpio-cells = <1>;

What about all the standard gpio controller properties?
