Linus Walleij 2a144dd091 tools/gpio: add the gpio-hammer tool ... 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] Tested-by: Michael Welling <mwelling@ieee.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>		2016-06-15 09:29:04 +02:00
