Subject[PATCH v3 0/6] power: supply: max17040 support compatible devices
Date
The max17040 fuel gauge is part of a family of 8 chips that have very similar
mode of operations and registers.

This patch set adds:
- compatible strings for all supported devices and handles the minor
differences between them;
- handling for devices reporting double capacity via maxim,double-soc;
- handling for setting rcomp, a compensation value for more accurate reading,
affected by battery chemistry and operating temps;
- suppot for SOC alerts (capacity changes by +/- 1%), to prevent polling every
second;
- improved max17040 driver with regmap and devm_

The datasheets of the supported devices are linked [0] [1] [2] [3].
