| 2024-06-12 | Documentation: gpio: Clarify effect of active low flag on line edges | Kent Gibson | |
| The documentation does not make sufficiently clear that edge polarity is based on changes to the logical line values, and that the physical polarity of edges is dependent on the active low flag. Clarify the relationship between the active low flag and edge polarity for the functions that read edge events. Suggested-by: David C.

| Add documentation for the GPIO character device userspace API. Added to the userspace-api book, but also provide a link from the admin-guide book, as historically the GPIO documentation has been there.
