Charging a Battery with Zephyr
summary
Zephyr now contains an upstreamed charger driver API with three handlers: get_property, set_property and charge_enable handler, plus a sample application that runs an infinite charging task loop polling the charger online status, switching on charging, reading charge type/health and ending on full. Device tree uses battery.yaml for static pack specs, properties are extensible for vendor fields, and an online notifier supports interrupt-based chips; limiting charge to 85% is done in application by setting the appropriate property.
