tools/gpio: add install section

2016-06-23T09:07:13+00:00

Allow user to call install target. Signed-off-by: Andy Shevchenko Acked-by: Alexandre Courbot Tested-by: Alexandre Courbot Signed-off-by: Linus Walleij

tools/gpio: move to tools buildsystem

2016-06-23T09:07:13+00:00

There is a nice buildsystem dedicated for userspace tools in Linux kernel tree. Switch gpio target to be built by it. Signed-off-by: Andy Shevchenko Acked-by: Alexandre Courbot Tested-by: Alexandre Courbot Signed-off-by: Linus Walleij

tools/gpio: add the gpio-event-mon tool

2016-06-15T07:29:29+00:00

The gpio-event-mon is used from userspace as an example of how to monitor GPIO line events. It will latch on to a certain GPIO line on a certain gpiochip and print timestamped events as they arrive. Example output: $ gpio-event-mon -n gpiochip2 -o 0 -r -f Monitoring line 0 on gpiochip2 Initial line value: 1 GPIO EVENT 946685798487609863: falling edge GPIO EVENT 946685798732482910: rising edge GPIO EVENT 946685799115997314: falling edge GPIO EVENT 946685799381469726: rising edge Signed-off-by: Linus Walleij

tools/gpio: add the gpio-hammer tool

2016-06-15T07:29:04+00:00

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

tools/gpio: create GPIO tools

2016-02-09T10:09:48+00:00

This creates GPIO tools under tools/gpio/* and adds a single example program to list the GPIOs on a system. When proper devices are created it provides this minimal output: Cc: Johan Hovold Cc: Michael Welling Cc: Markus Pargmann Signed-off-by: Linus Walleij
