    max17047 is improved version of max17042 chip. It has few HW bug
    fixes with minor changes in register set.

    max17050 is same as max17047 chip except its silicon packging. So from
    driver's point of view there is no difference btw max1047 and max1050.

    This patch adds the support to dynamically detect the chip type and
    adds steps to initialize the max17047 chip.

  • f3a71a6eb   max17042: Add POR init procedure from Maxim appnote ... Browse Code »

    Add power on reset (POR) init procedure defined by the maxim
    appnote. Using this procedure ensures that the part is
    configured/initialized correctly at POR and improves early accuracy of
    the fuel gauge and informs the fuel gauge with the battery
    characterization parameters. The battery characterization parameters
    come from the maxim characterization procedure.

    The MAX17042 is a fuel gauge with an I2C interface for lithium-ion
    betteries. Unlike its predecessor MAX17040, MAX17042 uses 16bit
    registers. Besides, MAX17042 has much more features than MAX17040; e.g.,
    a thermistor, current and current accumulation measurement, battery
    internal resistance estimate, average values of measurement, and others.

    This patch implements a driver for MAX17042.
    In this initial release, we have implemented the most basic features of
    a fuel gauge: measure the battery capacity and voltage.
