Subject[PATCH v4 0/7] power: supply: max17040 support compatible devices
From: Iskren Chernev <>

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
- improved max17040 driver with regmap and devm_

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



Changes in v4:
- split refactor patch into devm_ and regmap patches (as suggested by
Sebastian Reichel)
- correct handling of soc alert for double-soc devices
- rebased on 5.9-rc, incorporating upstream work
