joycond is a daemon which uses the evdev devices provided by hid-nintendo (formerly known as hid-joycon) to implement joycon pairing.
This is the Android-specific AIDL-based fork for LineageOS.
hid-nintendo is currently upstream in mainline Linux, but this is intended for the updated downstream k4.9 version.
This version is intended to be controlled by Android userspace control panels and props. The latest version is built to allow in-place updating of layouts and settings.
