| This charger is a sub-node of one of the 8941 PMIC blocks, and is specified |
| as a child node in DTS of that node. See ../mfd/qcom,spmi-pmic.txt and |
| ../mfd/qcom-pm8xxx.txt |
| |
| Example: |
| |
| pm8941@0 { |
| coincell@2800 { |
| compatible = "qcom,pm8941-coincell"; |
| reg = <0x2800>; |
| |
| qcom,rset-ohms = <2100>; |
| qcom,vset-millivolts = <3000>; |
| }; |
| }; |
