ARM: dts: qcom: msm8974-lge-nexus5: Add fuel gauge (45dfa741) · Commits · 戴 / test

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. Signed-off-by:
