I have just tested the dts again. My configruation is a tact switch
connecting the line to ground. The line is internally pulled up. When i
used:
gpios = <&gpio3 9 0x0>;
The letters apperead when i released the button, not when i pressed it.
When i changed to:
gpios = <&gpio3 9 0x1>;
The letters apperad on a button press. It seems like is the way around.
1 means falling edge and 0 is rising edge. Is this correct?

This is 3.8+.
So is gpio2 = &gpio3? Then in my case, if my button lines are internally
pulled up and the keys short them to gnd, should i use:
gpios = <&gpio3 9 0x0>; ?
Correct
