[PATCH 0/5] gpio: notify user-space about config changes in the kernel

From: Bartosz Golaszewski
Date: Fri Oct 04 2024 - 10:44:17 EST


We currently only emit events on changed line config to user-space on
changes made from user-space. Users have no way of getting notified
about in-kernel changes. This series improves the situation and also
contains a couple other related improvements.

Bartosz Golaszewski (5):
gpiolib: use v2 defines for line state change events
gpiolib: unify two loops initializing GPIO descriptors
gpio: cdev: update flags at once when reconfiguring from user-space
gpiolib: simplify notifying user-space about line requests
gpiolib: notify user-space about in-kernel line state changes
