ARM: dts: qcom: msm8974-klte: Add fuel gauge (da8d4699) · Commits · 戴 / test

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. Signed-off-by:
