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].
