Hi Sanjay, the issue still exists on vexpress Android build #331

https://android-build.linaro.org/builds/~linaro-android/vexpress-
linaro/#build=331

The GPIO column is empty there. The version of PowerDebug now shows
0.7.2, have your patch been merged?

** Description changed:

  On ARM Versatile Express A9 board with Linaro Android image:
  
  https://android-build.linaro.org/builds/~linaro-android/vexpress-
  linaro-13.09-release/#build=6
  
  Information is unavailable on "Clocks" & "Gpio" after launched
  powerdebug version 0.7.1, error output shows as below:
  
  root@vexpress:/ # powerdebug
  failed to initialize clock details (check debugfs)
  error: unable to open directory /sys/class/gpio
  failed to initialize gpios
  root@vexpress:/ #
  
  Please refer to attachment to get snapshot pictures.
  
  Note:
  
  Please run powerdebug in ADB shell, which the output is well formatted,
  however the failure is same as run in serial console.
  
  Latest update for this bug is the behaviour shows as described in
  comment #9, only GPIO information is unavailable.
