max17042_battery: Add support for max17047/50 chip 2012-05-06T03:28:11+00:00 Ramakrishna Pallala ramakrishna.pallala@intel.com 2012-05-05T09:04:26+00:00 9a8422d205ea142a27c2573e5ca3d2cc87d75260 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.

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.
