Charging a Battery with Zephyr
summary
Zephyr now includes an upstreamed charger driver API with three handlers (get_property, set_property, charge_enable) plus a shared battery DT binding (battery.yaml), a sample charger sample application that runs a charging task loop and polls charger status, and an online notifier for interrupted chips. It programs concrete charge profiles (conditioning, CC, CV, termination), sets protections (OCL, OVL, temp), allows vendor extensions to properties, and supports limiting charge (e.g., 85%) in application code; future work targets a generic GPIO charger driver and charger telemetry.
