[PATCH v2 0/3] gpio: add kunit tests for GPIO core

Posted by Bartosz Golaszewski 4 days, 15 hours ago

This series adds a first batch of kunit tests for GPIO core. I intend to
gradually add more coverage for functionalities that can't really be
tested from user-space with the existing kernel selftests or libgpiod
tests.

Merging strategy: with an Ack from kunit maintainers, this can go
through the GPIO tree for v7.2.

  taken
