+Qualcomm Battery Measurement System
+
+The Qualcomm Battery Measurement System is found inside of Qualcomm PM8941
+PMICs. It provides OCV and coulomb counter registers that allow the kernel
+to infer a capacity level.
+
+Required properties:
+- compatible: Should contain "qcom,pm8941-bms".
+- reg: Specifies the SPMI address and length of the
+ controller's registers.
+- interrupts: OCV threshold interrupt.
+- io-channels: Should contain IIO channel specifier for the
+ ADC channel that reports battery temperature.
+- io-channel-names: Should contain "temp".
+- qcom,fcc-temp-legend: An array containing the temperature, in degC,
+ for each column of the FCC lookup table.
+- qcom,fcc-lut: An array of FCC values in mah, one entry for each
+ temperature defined in in qcom,fcc-temp-legend.
+- qcom,ocv-temp-legend: An array containing the temperature, in degC,
+ for each column of the OCV lookup table.
+- qcom,ocv-capacity-legend: An array containing the capacity for each
+ row of the OCV lookup table.
+- qcom,ocv-lut: An array of OCV values in mV, one entry for each
+ capacity defined in qcom,ocv-capacity-legend.
+
+Example:
+
+ pm8941_vadc: vadc@3100 {
+ compatible = "qcom,spmi-vadc";
+ reg = <0x3100>;
+ interrupts = <0x0 0x31 0x0 IRQ_TYPE_EDGE_RISING>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+ #io-channel-cells = <1>;
+
+ bat_temp {
+ reg = <VADC_LR_MUX1_BAT_THERM>;
+ };
+ };
+
+ bms@4000 {
+ compatible = "qcom,pm8941-bms";
+ reg = <0x4000>;
+ interrupts = <0x0 0x40 0x4 IRQ_TYPE_EDGE_RISING>;
+ interrupt-names = "ocv_thr";
+
+ io-channels = <&pm8941_vadc VADC_LR_MUX1_BAT_THERM>;
