Battery Data is a collection of batteryprofile data made available to the QPNP Charger and BMS drivers via devicetree.
バッテリデータはバッテリ構成データの集合であり、デバイスツリーを介してQNP充電器とBMS駆動で使用される.
Batter-dataには、バッテリプロファイルノードとして作成される任意の数のサブノードが含まれます.

qcom,battery-data node required properties( ):
- qcom,rpull-up-kohm : The vadc pullupresistor's resistance value in kOhms.
Vadc
- qcom,vref-batt-therm-uv : The vadcvoltage used to make readings.
ForQualcomm VADCs this should be 1800000uV.
qcom,battery-data node optional properties:
- qcom,batt-id-range-pct : The area ofvariation between upper and lower bound
forwhich a given battery ID resistance is valid. This
valueis expressed as a percentage of the specified kohm
resistanceprovided by qcom,batt-id-kohm.
qcom,battery-data can also include anynumber of children nodes. These children
nodes will be treated as battery profiledata nodes.Batter-dataには、バッテリプロファイルノードとして作成される任意の数のサブノードが含まれます.
