/*
 * MFD core driver for the X-Powers' Power Management ICs
 *
 * AXP20x typically comprises an adaptive USB-Compatible PWM charger, BUCK DC-DC
 * converters, LDOs, multiple 12-bit ADCs of voltage, current and temperature
 * as well as configurable GPIOs.
 *
 * This file contains the interface independent core functions.
