kernel/tools/gpio/gpio-utils.c, branch linux-5.1.yHosts the 0x221E linux distro kernel.https://universe.0xinfinity.dev/distro/kernel/atom?h=linux-5.1.y2017-10-06T22:03:14Ztools: gpio: Print error string on IOCTL failures2017-10-06T22:03:14ZJacopo Mondijacopo+renesas@jmondi.org2017-09-28T13:01:44Zurn:sha1:d327a224ba2cbe234d82fd560ff8e5bb38b0bb4b
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.

tools/gpio: add gpio basic opereations2016-10-24T14:33:11ZBamvor Jian Zhangbamvor.zhangjian@linaro.org2016-10-14T02:48:25Zurn:sha1:e1acec0e750012edb2a2122b397a40f783c2aa1e
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.

tools/gpio: create GPIO tools2016-02-09T10:09:48ZLinus Walleijlinus.walleij@linaro.org2015-10-21T13:45:54Zurn:sha1:6d591c46bce037696d173bd5c8461b2b4bb680ad
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:
