Binding for sc8990 Li-Ion Charger
|
|
This driver will support the sc89890. There are
|
other ICs in the same family but those have not been tested.
|
|
Required properties:
|
- compatible: "sc,sc89890"
|
- reg: integer, i2c address of the device.
|
- interrupts: interrupt line;
|
- sc,battery-regulation-voltage: integer, maximum charging voltage (in uV);
|
- sc,charge-current: integer, maximum charging current (in uA);
|
- sc,termination-current: integer, charge will be terminated when current in
|
constant-voltage phase drops below this value (in uA);
|
- sc,precharge-current: integer, maximum charge current during precharge
|
phase (in uA);
|
- sc,minimum-sys-voltage: integer, when battery is charging and it is below
|
minimum system voltage, the system will be regulated above
|
minimum-sys-voltage setting (in uV);
|
- sc,boost-voltage: integer, VBUS voltage level in boost mode (in uV);
|
- sc,boost-max-current: integer, maximum allowed current draw in boost mode
|
(in uA).
|
|
Example:
|
|
sc89890 {
|
compatible = "sc,sc89890";
|
reg = <0x6a>;
|
|
interrupt-parent = <&gpio0>;
|
interrupts = <RK_PD5 IRQ_TYPE_EDGE_FALLING>;
|
|
sc,battery-regulation-voltage = <4200000>;
|
sc,charge-current = <1000000>;
|
sc,termination-current = <50000>;
|
sc,precharge-current = <128000>;
|
sc,minimum-sys-voltage = <3600000>;
|
sc,boost-voltage = <5000000>;
|
sc,boost-max-current = <1000000>;
|
sc,ibatcomp-micro-ohms = <10>;
|
};
