Subject: [PATCH 2/2] arm64: dts: qcom: pm8916: Add batt_id channel node
Date: Wed, 13 Jan 2021 16:18:08 +0100 [thread overview]
Message-ID: <20210113151808.4628-3-jonathan.albrieux@gmail.com> (raw)
In-Reply-To: <20210113151808.4628-1-jonathan.albrieux@gmail.com>
Working on a battery charger and fuel gauge driver it happened to
have the need to read from VADC_LR_MUX2_BAT_ID channel. Here is
the declaration from downstream msm8916.dtsi:
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>;
};
Add VADC_LR_MUX2_BAT_ID accordingly.
