selftests: gpio: Use "grep -E" instead of "egrep"

2022-11-25T17:57:23Z

The latest version of grep claims the egrep is now obsolete so the build now contains warnings that look like: egrep: warning: egrep is obsolescent; using grep -E fix this up by moving the related file to use "grep -E" instead. sed -i "s/egrep/grep -E/g" `grep egrep -rwl tools/testing/selftests/gpio` Here are the steps to install the latest grep: wget http://ftp.gnu.org/gnu/grep/grep-3.8.tar.gz tar xf grep-3.8.tar.gz cd grep-3.8 && ./configure && make sudo make install export PATH=/usr/local/bin:$PATH Signed-off-by: Tiezhu Yang Signed-off-by: Shuah Khan

selftests: gpio: add test cases for gpio-sim

2021-12-17T11:26:13Z

Add a set of tests for the new gpio-sim module. This is a pure shell test-suite and uses the helper programs available in the gpio selftests directory. These test-cases only test the functionalities exposed by the gpio-sim driver, not those handled by core gpiolib code. Signed-off-by: Bartosz Golaszewski
