| Qualcomm Coincell Charger:
|
| The hardware block controls charging for a coincell or capacitor that is
| used to provide power backup for certain features of the power management
| IC (PMIC)
|
| - compatible:
| Usage: required
| Value type: <string>
| Definition: must be: "qcom,pm8941-coincell"
|
| - reg:
| Usage: required
| Value type: <u32>
| Definition: base address of the coincell charger registers
|
| - qcom,rset-ohms:
| Usage: required
| Value type: <u32>
| Definition: resistance (in ohms) for current-limiting resistor
| must be one of: 800, 1200, 1700, 2100
|
| - qcom,vset-millivolts:
| Usage: required
| Value type: <u32>
| Definition: voltage (in millivolts) to apply for charging
| must be one of: 2500, 3000, 3100, 3200
|
| - qcom,charger-disable:
| Usage: optional
| Value type: <boolean>
| Definition: defining this property disables charging
|
| 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>;
| };
| };
