Subject: [PATCH 1/2] iio:adc:qcom-spmi-vadc: add default scale to LR_MUX2_BAT_ID channel
Date: Wed, 13 Jan 2021 16:18:07 +0100 [thread overview]
Message-ID: <20210113151808.4628-2-jonathan.albrieux@gmail.com> (raw)
In-Reply-To: <20210113151808.4628-1-jonathan.albrieux@gmail.com>
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.
