Add to error messages the error description by concatenating output of strerror() function to error messages print out by gpio-utils.c on IOCTL failures. Rationalize error messages, while at there, making all of them look the same. Signed-off-by: Jacopo Mondi Signed-off-by: Linus Walleij

tools/gpio: add gpio basic opereations

2016-10-24T14:33:11+00:00

Add basic gpio operations. User could get/set gpio value for specific line of gpiochip. Reference "tools/gpio/gpio-hammer.c" or "tools/testing/selftest/gpio/gpio-mockup-chardev.c" for how to use it. Signed-off-by: Bamvor Jian Zhang Reviewed-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
