tools: gpio: rename nlines to num_lines

2020-09-30T08:57:17Z

Rename nlines to num_lines to be consistent with other usage for fields describing the number of entries in an array. Signed-off-by: Kent Gibson Reviewed-by: Andy Shevchenko Signed-off-by: Bartosz Golaszewski

tools: gpio-hammer: Apply scripts/Lindent and retain good changes

2020-03-25T08:50:46Z

"retain good changes" means that I left the help string split up instead of having this weird thing where it tries to merge together the last three lines and it looks **really** bad Signed-off-by: Gabriel Ravier Signed-off-by: Bartosz Golaszewski

tools: gpio-hammer: fix spelling mistake: "occurences" -> "occurrences"

There is a spelling mistake in an error message. Fix it. Signed-off-by: Colin Ian King Signed-off-by: Bartosz Golaszewski

tools: gpio-hammer: Avoid potential overflow in main

2020-03-25T08:50:45Z

If '-o' was used more than 64 times in a single invocation of gpio-hammer, this could lead to an overflow of the 'lines' array. This commit fixes this by avoiding the overflow and giving a proper diagnostic back to the user Signed-off-by: Gabriel Ravier Signed-off-by: Bartosz Golaszewski

tools/gpio: add the gpio-hammer tool

2016-06-15T07:29:04Z

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 Signed-off-by: Linus Walleij
