I would like to create an automated test-suite for libgpiod, but the gpio-mockup driver is quite limited when it comes to current user space functionality - I can't test neither line event notifications nor finding GPIO lines by name.
This series proposes to extend the gpio framework by allowing to inject line events from the kernel code and by providing a debugfs interface for that to the gpio-mockup driver. We also allow the user to request that the mockup driver name the lines. The first patch contains only minor clean-ups. Patches 2/7-4/7 implement the in-kernel mechanism for injecting events, while patch 5/7 extends the mockup driver to provide a relevant debugfs interface. Patch 6/7 adds a new module param allowing to request naming of the lines. The last patch contains some coding style tweaks.
