-Binding for Richtek rt9455 battery charger
-
-Required properties:
-- compatible: it should contain one of the following:
- "richtek,rt9455".
-- reg: integer, i2c address of the device.
-- interrupts: interrupt mapping for GPIO IRQ, it should be
- configured with IRQ_TYPE_LEVEL_LOW flag.
-- richtek,output-charge-current: integer, output current from the charger to the
- battery, in uA.
-- richtek,end-of-charge-percentage: integer, percent of the output charge current.
- When the current in constant-voltage phase drops
- below output_charge_current x end-of-charge-percentage,
- charge is terminated.
-- richtek,battery-regulation-voltage: integer, maximum battery voltage in uV.
-- richtek,boost-output-voltage: integer, maximum voltage provided to consumer
- devices, when the charger is in boost mode, in uV.
-
-Optional properties:
-- richtek,min-input-voltage-regulation: integer, input voltage level in uV, used to
- decrease voltage level when the over current
- of the input power source occurs.
- This prevents input voltage drop due to insufficient
- current provided by the power source.
- Default: 4500000 uV (4.5V)
-- richtek,avg-input-current-regulation: integer, input current value in uA drained by the
- charger from the power source.
- Default: 500000 uA (500mA)
-
-Example:
-
-rt9455@22 {
- compatible = "richtek,rt9455";
- reg = <0x22>;
-
- interrupt-parent = <&gpio1>;
- interrupts = <0 IRQ_TYPE_LEVEL_LOW>;
-
- richtek,output-charge-current = <500000>;
- richtek,end-of-charge-percentage = <10>;
- richtek,battery-regulation-voltage = <4200000>;
- richtek,boost-output-voltage = <5050000>;
-
- richtek,min-input-voltage-regulation = <4500000>;
- richtek,avg-input-current-regulation = <500000>;
