[PATCH 0/2] Allow VADC_LR_MUX2_BAT_ID channel proper reading

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>;
	};

Those two patches set channel scaling accordingly and add it to
pm8916 device tree.

Jonathan Albrieux (2):
  iio:adc:qcom-spmi-vadc: add default scale to LR_MUX2_BAT_ID channel
  arm64: dts: qcom: pm8916: Add batt_id channel node

Add VADC_LR_MUX2_BAT_ID accordingly.
