[PATCH 2/2] ARM: dts: qcom: msm8974-lge-nexus5: Add fuel gauge

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
