   2 * MFD core driver for the X-Powers' Power Management ICs
   3 *
   4 * AXP20x typically comprises an adaptive USB-Compatible PWM charger, BUCK DC-DC
   5 * converters, LDOs, multiple 12-bit ADCs of voltage, current and temperature
   6 * as well as configurable GPIOs.
   7 *
   8 * This file contains the interface independent core functions.
