Checking at both msm8909-pm8916.dtsi and msm8916.dtsi from downstream it is indicated that "batt_id" channel has to be scaled with the default function: chan@31 { label = "batt_id"; reg = <0x31>; qcom,decimation = <0>; qcom,pre-div-channel-scaling = <0>; qcom,calibration-type = "ratiometric"; qcom,scale-function = <0>; qcom,hw-settle-time = <0xb>; qcom,fast-avg-setup = <0>; }; Change LR_MUX2_BAT_ID scaling accordingly.
