  The gpio-hammer is used from userspace as an example of how
  to retrieve a GPIO handle for one or several GPIO lines and
  hammer the outputs from low to high and back again. It will
  pulse the selected lines once per second for a specified
  number of times or indefinitely if no loop count is
  supplied.

  Example output:
  $ gpio-hammer -n gpiochip0 -o5 -o6 -o7
  Hammer lines [5, 6, 7] on gpiochip0, initial states: [1, 1, 1]
  [-] [5: 0, 6: 0, 7: 0]
