Spreadtrum SC2731 PMIC battery charger binding
|
|
Required properties:
|
- compatible: Should be "sprd,sc2731-charger".
|
- reg: Address offset of charger register.
|
- phys: Contains a phandle to the USB phy.
|
|
Optional Properties:
|
- monitored-battery: phandle of battery characteristics devicetree node.
|
The charger uses the following battery properties:
|
- charge-term-current-microamp: current for charge termination phase.
|
- constant-charge-voltage-max-microvolt: maximum constant input voltage.
|
See Documentation/devicetree/bindings/power/supply/battery.txt

Example:
|
|
bat: battery {
|
compatible = "simple-battery";
|
charge-term-current-microamp = <120000>;
|
constant-charge-voltage-max-microvolt = <4350000>;
|
......
|
};
