+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>;
+ };
+ };
