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: definining 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>;

		};

	};
