The Samsung Galaxy S5 uses a maxim17048 fuelgauge. The maxim,rcomp value
is taken from downstream kernel. Model data and temperature-based
compensation are not yet supported in the mainline driver, but the
readings seem fine nevertheless.

The LG Nexus 5 uses a maxim17048 fuelgauge. The maxim,rcomp value is
taken from downstream dt. Temperature-based compensation is not yet
supported in the mainline driver, but the readings seem fine nevertheless.
