Hi Linaro,

I am trying to attach interrupt handlers to the push buttons on the arndale board. Your patch adds in dts information on the push buttons

menu {

•                   label = "SW-TACT2";
  

•                   gpios = <&gpx1 4 1>;
  

•                   linux,code = <139>;
  

•                   gpio-key,wakeup;
  

•           };
  
  

I assume that <139> is the GPU number in base 10. Is this correct ?

No, that is the key code for MENU button, as defined in include/uapi/linux/input.h.

Also what is the significance of gpx1 and 4 1 ?

This tells us that we are using GPX1[4] gpio for this operation.
