selftests: gpio: override clean in lib.mk to fix warnings

2017-04-25T15:47:28Z

Add override for lib.mk clean to fix the following warnings from clean target run. Makefile:11: warning: overriding recipe for target 'clean' ../lib.mk:55: warning: ignoring old recipe for target 'clean' Signed-off-by: Shuah Khan

selftests: gpio: add config fragment for gpio-mockup

2017-04-21T17:25:41Z

The gpio test requires to insert the gpio mockup module (CONFIG_GPIO_MOCKUP). The gpio mockup driver depends on gpiolib (CONFIG_GPIOLIB). CONFIG_GPIO_SYSFS is selected automatically by the gpio mockup driver. Tested on x86_64 and arm64 with defconfig and kselftest-merge. Signed-off-by: Fathi Boudra Signed-off-by: Shuah Khan

selftest/gpio: add gpio test case

2016-12-13T14:26:37Z

This test script try to do whitebox testing for gpio subsystem(based on gpiolib). It manipulate gpio device through chardev or sysfs and check the result from debugfs. This script test gpio-mockup through chardev by default. User could test other gpio chip by passing the module name. Some of the testcases are turned off by default to avoid the conflicting with gpiochip in system. In details, it test the following things: 1. Test direction and output value for valid pin. 2. Test dynamic allocation of gpio base. 3. Add single, multi gpiochip to do overlap check. Run "tools/testing/selftests/gpio/gpio-mockup.sh -h" for usage.
