/**
 * @file Power.cpp
 * @brief This file contains the implementation of the Power class, which is
 * responsible for managing power-related functionality of the device. It
 * includes battery level sensing, power management unit (PMU) control, and
 * power state machine management. The Power class is used by the main device
 * class to manage power-related functionality.
 *
 * The file also includes implementations of various battery level sensors, such
 * as the AnalogBatteryLevel class, which assumes the battery voltage is
 * attached via a voltage-divider to an analog input.
 *
 * This file is part of the Meshtastic project.
 * For more information, see: https://meshtastic.org/
