| 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>; |
| }; |
